Assorted changes from FreeBSD. Might be some slight compatibility hiccoughs with some sources - might need to #include a bit more before <net/if.h>.

Version 5.23. Tagged as 'TCPIPLibs-5_23'

Altered the definition of struct tftphdr so that it declares it in a way that the compiler does not pad out a non-word aligned union.  This would breaks backward compatibility - except that nothing using this structure before would have worked anyway.

Not tagged.

Version 5.22. Tagged as 'TCPIPLibs-5_22'

Version 5.21. Tagged as 'TCPIPLibs-5_21'

Header changes required by Internet 5.27. Note that these changes affect the layout of several structures peeked by such tools as InetStat. These will need recompiling for Internet 5.27.

Version 5.20. Tagged as 'TCPIPLibs-5_20'

See LibraryDoc for details.

Version 5.19. Tagged as 'TCPIPLibs-5_19'

Detail:
  Service_InternetStatus/DHCPInform is issued whenever a response to a
    DHCPINFORM is received.
  Modules which claim sub-reason code 3 (DynamicBootStart) can now alter
    R2 (if they claim the reason code) to contain the return value for
    the Internet module's ioctl handler.  Previously, the Internet module
    always returned EADDRUNAVAIL if the service call was claimed, which
    meant that callers had to use other means to determine whether the
    dynamic boot had completed (eg. by querying the DHCP module directly)
Admin:
  Documentation file LibraryDoc updated with details.
  Required by Internet 5.25 and later.
  Required by DHCP 0.05 and later.

Version 5.18. Tagged as 'TCPIPLibs-5_18'

if_multiaddrs moved to end of struct ifnet to save binary compatibility grief with all those horrid little progs like inetstat and ifconfig that inspect the Internet module's internal structures directly.

Version 5.17. Tagged as 'TCPIPLibs-5_17'

Added if_multiaddrs member to struct ifnet to allow Internet module to keep track of required multicast addresses. Similar to ac_multiaddrs in struct arpcom, but we require logical addresses, not just MAC addresses, for DCI.

Version 5.16. Tagged as 'TCPIPLibs-5_16'

Changed all remaining occurrences of __const with const to match the other references to it in unistd.h.  This fixes compilation in

-pcc mode.

Version 5.15. Tagged as 'TCPIPLibs-5_15'

Detail:
  A new function has been declared for generating initial sequence
    numbers for the Internet module's TCP implementation.  More details
    in Internet module logs.
Admin:
  Required by Internet 5.22
    (CVS: RiscOS/Sources/Networking/AUN/Internet  tag: Internet-5_22)

Version 5.14. Tagged as 'TCPIPLibs-5_14'

Detail:
  The low-level malloc and free calls made by the RPC and XDR libraries
    can now be intercepted if an application defined the two functions
    _rpclib_malloc and _rpclib_free with appropriate prototypes as per
    malloc and free.  This means that you can override the default
    behaviour of stuffing the data into the RMA if you want to, but that
    the default of using the RMA is retained.
Admin:
  Tested with the NFS module.
  Required by NFS 3.00 and later (CVS tag: NFS-3_00)

Version 5.13. Tagged as 'TCPIPLibs-5_13'

No longer #defines away const, volatile etc when compiling -pcc.

Version 5.12. Tagged as 'TCPIPLibs-5_12'

Admin:
  Required by Internet 5.21, DHCP 0.01, IPConfig 0.15.

Version 5.11. Tagged as 'TCPIPLibs-5_11'

  Added remaining options from RFC2132.
Detail:
  The Internet module contained the DHCP option numbers for various
    extensions defined in RFC2132.  The protocols/dhcp.h header file
    now holds those, plus the remaining missing ones from the RFC.
Admin:
  Built Internet 5.21 against new header file to verify it still works.

Detail
    In net/if.h struct if_data was defined within struct ifnet, but also
    referred to later outside of struct ifnet.  This is fine in C since
    the scope of strutures persists to the end of the translation unit, but
    in C++ it persists until the end of the block.

    This problem is solved by moving the definition of struct if_data out
    of struct ifnet and into the outermost level, as it is in the current
    FreeBSD sources.

    In sys/mbuf.h there were two defintions of struct mbuf; one was for ANSI C
    and one was for K&R C, and the appropriate one was chosen by testing whether
    __STDC__ was defined or not.  The ANSI C version of the structure has
    const members in it, which C++ does not allow unless the structure/class
    has a constructor (since const members can only be initialised in a
    constructor's initialiser-list).  The C++ standard says that use of
    __STDC__ is implementation defined, which means we can't rely on picking up
    the non-ANSI C version of the structure in C++ code.

    A third definition of the structure has been added, which is used if
    __cplusplus is defined.  It retains the const members, but declares a
    private constructor, which keeps the compiler happy with respect to the
    const members.  Under the terms of the C++ standard, this is still a
    'P.O.D.' (Plain Old Data) structure, so it is guaranteed to have the same
    storage layout as the C one.  In addition, the m_sys* members have been
    made private, since the client should never access these.
Admin
    Tested with the ATM driver to verify the the changes work with C++.
    Tested with PPP to ensure that things still work for C.
    Version incremented to 5.10 and tagged.

Version 5.10. Tagged as 'TCPIPLibs-5_10'

Updated details of the Service_InternetStatus service call, including all the new reason codes I've added for the DHCP module to integrate into the rest of the system.

Detail:
  Added a new ioctl (SIOCGWHOIAMD) for the private use of the
    DHCP module.
  Defined structure for ioctl data in protocols/dhcp.h.  The
    "ifr_flags" field is the union part that is used to pass
    action flags to Internet.
  Updated comment that protocol is defined by RFC2131 & RFC2132.
Admin:
  Software which includes protocols/dhcp.h may need modification
    to ensure that net/if.h is included too, as it requires a
    definition of struct ifreq.  No software in Renaissance is
    believed to be affected currently.
  Required by Internet 5.20
    (Internet-5_20 in RiscOS/Sources/Networking/AUN/Internet)
  Required by DHCP 0.00
    (DHCP-0_00 in RiscOS/Sources/Networking/DHCP)


Version 5.09. Tagged as 'TCPIPLibs-5_09'

  Correct spelling of macro
Detail:
  OPTION_DHCPMESSAGETYPE now spelt correctly! (not "DCHP")
  DHCPINFORM message type added for completeness as per RFC2131.
Admin:
  Not tagged yet.

Detail:
  Makefile now defines COMPAT_INET4 not DOMPAT_INET4 (!)
  Makefile no longer lists the ALF file contents after building them.
  64-bit bit XDR routines now pass pointers to the fields in the 64-bit
    structure, not the fields themselves.  Previously this meant that
    attempting to XDR_DECODE any 64-bit quantity would cause a data
    abort.
Admin:
  Tested as underlying support library for updated NFS module which
    implements NFSv3.

Version 5.08. Tagged as 'TCPIPLibs-5_08'

  Port discovery function now prototyped!
Detail:
  64-bit support has been added to XDR for any protocols that might
    need it (eg. NFS3)
  getrpcport now has a prototype (rpc/netdb.h)
Admin:
  Tested by building the NFS3 lower-level support files from the
    protocol definition file and verified that the rpcgen generated
    code would compile and link without error.
  This version represents issue 1 of 1215,201/DR and 1215,202/DR.
  This version (5.07) is associated with AMR 5201.

Version 5.07. Tagged as 'TCPIPLibs-5_07'

  New InternetStatus service call reason codes added and documented.
Detail:
  clnt_tcp.c added and TCP support recompiled in to other parts of RPC
    library.  Requested by Imagic.
  New macro definitions for InternetStatus_DynamicBootStart and
    InternetStatus_DynamicBootReply added to sys/dcistructs.h
  Documentation for new service calls added to LibraryDoc.
Admin:
  rusers application built against new RPC library to prove rpc/tcp
    support is present and correct.
  Required by Internet 5.19 and later.
    (CVS: RiscOS/Sources/Networking/AUN/Internet (tag: Internet-5_19)
  Required by IPConfig 0.09 and later.
    (CVS: RiscOS/Sources/Networking/IPConfig (tag: IPConfig-0_09)
  Required by development builds of LanManFS 2.00 and later.
    (CVS: RiscOS/Sources/Networking/Omni/Protocols/LanManFS;
          earliest tag: LanManFS-1_87_1_1_1_1_2_12 or LanManFS-2_00)


Version 5.06. Tagged as 'TCPIPLibs-5_06'

  New InternetStatus service call reason codes added and documented.
Detail:
  clnt_tcp.c added and TCP support recompiled in to other parts of RPC
    library.  Requested by third party.
  New macro definitions for InternetStatus_DynamicBootStart and
    InternetStatus_DynamicBootReply added to sys/dcistructs.h
  Documentation for new service calls added to LibraryDoc.
Admin:
  rusers application built against new RPC library to prove rpc/tcp
    support is present and correct.
  Required by Internet 5.19 and later.
    (CVS: RiscOS/Sources/Networking/AUN/Internet (tag: Internet-5_19)
  Required by IPConfig 0.09 and later.
    (CVS: RiscOS/Sources/Networking/IPConfig (tag: IPConfig-0_09)
  Required by development builds of LanManFS 2.00 and later.
    (CVS: RiscOS/Sources/Networking/Omni/Protocols/LanManFS;
          earliest tag: LanManFS-1_87_1_1_1_1_2_12 or LanManFS-2_00)


Version 5.06. Tagged as 'TCPIPLibs-5_06'

Detail:
  rpc/rpc.h now wraps all the sub-includes with C++ protection.
  rpc/svc.h prototypes ANSI-ised (rpc/rpc.h includes it, so despite services
    not being supported under RISC OS, it still needs to be there)
  rpc/xdr.h declares struct XDR as equivalent to XDR.
Admin:
  At least this version is required by code generated by rpcgen.

Version 5.05. Tagged as 'TCPIPLibs-5_05'

Prototypes upgraded to ANSI-style.  This is required so that C++ source code can include them (third party needs this)

  Removed duplicate headers from inside rpclib - now uses the exported headers
    which should avoid inconsistencies developing.
  No longer uses cc400 during builds.
Detail:
  Nearly every header is changed.  Parameter prototypes cross-checked against
    actual source code, Solaris 2.6 headers, and comments in the rpclib headers.
  Build improvement: no longer uses "cc400" to compile clnt_udp.c.  Previously
    this was done because newer compilers were alleged to generate broken code.
    The example quoted was the NFS module's free display.  The fault actually
    lies in the NFS module passing the wrong parameters to xdr_string!  Future
    builds of NFS will require TCPIPLibs-5_04 or later.
Admin:
  Built.  Tested by building NFS against it.  Verified free space display works
    properly (needs NFS 2.36).  Tested inclusion of all RPC headers from C++
    source file worked without warnings or errors.

Version 5.04. Tagged as 'TCPIPLibs-5_04'

Version 5.03. Tagged as 'TCPIPLibs-5_03'

notmember - relating to multicast reception & toolong - oversized IP packets.
Former is used in Internet 5.16+

Increased default maximum size of interface receive queue from 50 to 100 entries, since this has been causing data to be discarded in STB systems.

This header file contains a structure containing pointers to function, one of which declares a formal parameter named "new".  This has been renamed to "new_mbuf" to remove the compiler warning about the use of C++ reserved words in C code.

This update not tagged.

Version 5.02. Not tagged

Fixed macro names in DHCP header file.

Version 5.02. Tagged as 'TCPIPLibs-5_02'

* DCIVERSION incremented to 404
* MulticastRequest SWI number added
* Flags for MulticastRequest SWI added
* Selective multicast bit added to Inquire SWI flags
* Multicast filter capability flags added to Filter SWI flags
* Added new types to the stats interface type list
* Added half/full duplex bits to link status bits list
* Created link polarity bits list

Version 5.01. Tagged as 'TCPIPLibs-5_01'

Version 5.00. Tagged as 'TCPIPLibs-5_00'

Fixed broken macro definitions & broken comments and added the same comment about byte-order of the magic cookie as was previously put in bootp.h.
