Lots of changes since last version, at least the following:
* Updated OS timestamp, removed alpha status
* Negative INKEY OS version changed to &AA
* GraphicsV is now alocated vector number &2A
* ROM moved up to &FC000000
* Max application slot increased to 512 Mbytes (for now)
* Max size of RMA increased to 256 Mbytes
* RMA is now first-created dynamic area (so it gets lowest address after
top of application slot)
* OS_Memory 10 reimplemeted
* New OS_ReadSysInfo 6 values 18-22 added
* OS_ReadSysInfo 8 gains flag bit to indicate soft power-off
* Misc internal top-bit-set-address fixes
* *ChangeDynamicArea can take sizes in megabytes or gigabytes
* Magic word "&off" in R0 passed to OS_Reset powers down if possible
* Added acceleration: block copy; CLS; text window scroll up; rectangle
fill
* Disabled LED flashing in page mode (liable to crash)
* Masked sprite plot and VDU 5 text avoids reading the screen if possible
* Framestore made USR mode accessible
* Fix for VDU 5,127 bug - now relies on font definitions being in extreme
quarters of memory, rather than bottom half
* Allocated 64-bit OS_Convert... SWIs
* IIC errors use allocated error numbers
* Looks for Dallas RTC before Philips RTC because we're using a Philips
NVRAM device with the same ID
* Fix to bug that meant the oscillator in the Dallas RTC wasn't enabled
* Default mouse type (USB) changed to allocated number
* Ram disc max size increased to 128 Mbytes (Ursula merge) and made
cacheable for StrongARMs (not XScale)
* Branch through zero handler now works in USR mode, by use of a
trampoline in the system stack to allow PC-relative register storage
* Address exception handler changed to not use 0 as workspace
* OS_Memory 13 extended to allow specification of cacheability and access
privileges
* Added OS_Memory 16 to return important memory addresses
* RISCOS_MapInIO() takes cacheable flag in bit 3, access permissions in
bits 10 and 11, doubly-mapped flag in bit 20, and access permissions
specified flag in bit 21
* Bug fix in last version for application abort handlers didn't quite
work; register shuffle required
* "Module is not 32-bit compatible" error now reports the module name
* Default configured language changed from 10 to 11 (now Desktop again)
