CE C/C++ Toolchain (v14.0)

The v14.0 toolchain adds many functions, fixes bugs, and applies optimizations here and there.
Merry Christmas! 🎄

This release is brought to you in particular thanks to @ZERICO2005 who did almost all of the work!

Highlights:

• Massive expansion of libc functionality: strto*, atoi/atol/atoll, strlcat, memmem, memrmem, strrstr, stpncpy, strspn/strcspn/strpbrk, etc., many implemented/optimized in handwritten assembly.
• Added sscanf and vsscanf
• Wide-character and C95 additions: wint_t, <wctype.h>, <cfenv>, numerous wmem* and wcs* helpers.
• C++ library updates: added <complex>, improvements to <type_traits>, fixes to C++98 headers.
• Math and floating-point: new/optimized dtof, (u)lltod, logbf, ldexpf behavior fixes, and scalbln(f/l).
• IO and tooling fixes: fclose correctness, stdio.h cleanup/rename helpers, fileioc performance and docs, gfx_AllocSprite bug fix.

Changelog

Added

• String/number conversion:
  • Assembly implementations: strtol/strtoul, strtoll/strtoull, atoi/atol/atoll.
  • New helpers: __strtoi, __strtoui.
• String utilities:
  • sscanf/vsscanf.
  • strlcat, stpncpy, memmem, memrmem, strrstr, strspn, strcspn, strpbrk, strchrnul.
• Wide-character and locale:
  • wint_t, <wctype.h>, C95 wmem* functions, wcslen/wcsnlen.
• C/C++ headers and types:
  • <cfenv>; PRI24 and SCN24 in <inttypes.h>.
  • <cstdarg> added; fixes for (c)stddef under C89/C++98.
  • Expanded <type_traits>.
  • C++ <complex> added.
• Math/FP:
  • Assembly dtof, (u)lltod, logbf; optimized ilogbf, copysignl.
  • Implemented scalbln(f/l).
  • fminf/fmaxf in assembly.
• Testing/tooling/infra:
  • lots of tests for the above!
  • git-blame-ignore-revs added.
  • updated some CI things

Fixed

• fclose correctness; stdio.h cleanup and rename alias.
• Fix and optimize clipping behavior for gfx_HorizLine and gfx_VertLine (by @calc84maniac, fixes #673).
• Fixed fontlib_GetGlyphWidth.
• gfx_AllocSprite return value bug.
• ti_Alloc(String/Equ) now handles NULL from allocator; nonnull attributes added.
• ti_SetArchiveStatus prototype/declaration corrected.
• errno/perror strings updated; additional errno defines for compatibility (partially by @coco875, see #640).
• Replaced broken OS strspn/strcspn/strpbrk with in-house implementations (by @calc84maniac, fixes #646).
• some float handling edge cases, and endptr for strto(f/d/ld), fixed.
• <fenv.h> function-macros fixed; introduced <cfenv>.
• convimg: fix transparent-index and palette-offset (by @mateoconlechuga)
• Misc. docs fixes

Performance and Optimizations

• Multiplication helpers: inlined/optimized __llmul_b, __llmul_add_b_overflow; llmulu_b improvements and cycle count fixes.
• memmove optimized; zero-filling in calloc faster under __TICE__.
• File I/O: fileioc optimized.
• i48/i64 routines: implemented i48div, optimized i48div and i64 bitwise ops; added cycle counts and formatting for i48 CRT routines.
• ZX0 decompressor optimized using eZ80 instructions.
• Misc. size opts

The next release should also be major, as @mateoconlechuga is working on some standard-ification of the toolchain tools especially linking-wise, and @Sightem on fixing newer LLVM compiler rebase efforts (v15 -> v17). Stay tuned!
