  doc: Sort the ISO C and POSIX Function Substitutes by header file.
  
  * doc/gnulib.texi (Function Substitutes): Add one section per header
  file.
  * doc/posix-functions/*.texi: Each of these files is now a subsection.

  Portability problems not fixed by Gnulib:
  @itemize
  @item
  This function is missing on some platforms:
  NetBSD 3.0, OpenBSD 3.8, Minix 3.1.8, HP-UX 11.00, Cygwin 1.5.x.
  @item
  On Windows and 32-bit AIX platforms, @code{wchar_t} is a 16-bit type and therefore cannot
  accommodate all Unicode characters.
  @item
  On Windows, this function does not take a buffer size as second argument.
  @item
  This function does not support size specifiers as in C23 (@code{w8},
  @code{w16}, @code{w32}, @code{w64}, @code{wf8}, @code{wf16}, @code{wf32},
  @code{wf64}) on some platforms:
  glibc 2.37, musl libc, macOS 14, FreeBSD 13.2, NetBSD 10.0, OpenBSD 7.5, AIX 7.3, Solaris 11.4, Cygwin 3.5.3, mingw, MSVC, Android 9.0.
  @item
  This function does not support the @samp{b} directive, required by ISO C23,
  on some platforms:
  glibc 2.34, musl libc, macOS 14, FreeBSD 13.2, NetBSD 10.0, OpenBSD 7.5,
  AIX 7.3, HP-UX 11, Solaris 11.4, Cygwin 3.5.3, mingw, MSVC 14, Android 9.0.
  @item
  This function does not support the @samp{B} directive on some platforms:
  glibc 2.34, musl libc, macOS 14, FreeBSD 13.2, NetBSD 10.0, OpenBSD 7.5, AIX 7.3, Solaris 11.4, Cygwin 3.5.3, mingw, MSVC, Android 9.0.
  @item
  printf @code{"%#.0x"} or @code{"%#.0X"} with a zero argument yields an
  incorrect result (non-empty) on some platforms:
  Mac OS X 10.6.
  @item
  The @code{%m} directive is not portable, use @code{%s} mapped to an
  argument of @code{strerror(errno)} (or a version of @code{strerror_r})
  instead.
  @item
  In the C or POSIX locales, the @code{%c} and @code{%s} conversions may fail
  on some platforms:
  glibc 2.35.
  @item
  When formatting an integer with grouping flag, this function inserts thousands
  separators even in the "C" locale on some platforms:
  NetBSD 5.1.
