Detail:
  Was (trying to) clear the M32 flag in {CONFIG}=32.
  Ref: https://www.riscosopen.org/forum/forums/1/topics/15080?page=1#posts-99441
  Makefile updated to only pass rlib's txt switch when building rlib.

Detail:
  alloc.c - Add aligned_alloc(). Since softloaded versions of the C library can't rely on OS_Module 24 being available there is a fallback implementation for older kernels.
  stdlib.c - Add quick_exit() and at_quick_exit(). Also fix bug in _Exit; a missing loop pre-decrement led to only checking a single (out of array bounds!) vector.
  time.c - Add timespec_get().
  cl_entry2 - 4 new functions added to the stubs.
  Reduce spare CLib static workspace to absorb the quick_exit() handlers, remove the unused words from armsys.c so they're all accounted for in one space.
Admin:
  In order that the functions can be defined in the stubs now (despite not having a compiler to support C11/C18) they are enabled when 'DDE' is defined so that C library builds work.

Detail:
  assert.h - definition of static_assert
  complex.h - definition of CMPLX[F|L]
  float.h - various implementation defines
  stdio.h - hide gets() as it's been withdrawn
  wchar.h - guard mbstate_t as it can also be in uchar.h, fix missing __valist definition

Detail:
  Remove undocumented 't' mode which forcibly timestamped files, since other operating systems use this to denote a text file (as opposed to 'b' binary mode).
  Add 'x' mode per ISO9899:2018
  * only applies to 'w' mode files (not 'r' or 'a')
  * file must not exist prior to creation
  * beyond that we rely on RISC OS' policy of only allowing a file to be opened once for writing as our exclusivity
  Also fix bug in check for 'Protected disc' error, which only trigged for fsnumber_ADFS (8).

  Tested in a ROM build with a simple test harness.
