Remove unused function checks from configure.ac & include/*.h.in

The code that used getisax to check for MMX support was moved to pixman
and removed from the X server by commit eb2d7fe02f9cbc.

The code that used HAVE_MKSTEMP was deleted by the Xprint removal in
commit 1c8bd318fbaf.

All alloca calls were removed by the patch series end in commit 5e363500c8,
and used custom X checks instead of the autoconf HAVE_ALLOCA anyway.

I can find no record of HAVE_GETUID, HAVE_GETEUID, HAVE_LINK, HAVE_MEMMOVE,
HAVE_MEMSET, HAVE_STRCHR, HAVE_STRRCHR, HAVE_GETOPT, HAVE_GETOPT_LONG,
HAVE_DOPRNT, or HAVE_VPRINTF ever being used, and the calls to those
functions are not wrapped in #ifdefs.
(Most of those are in our baseline requirements of C89 & Unix98 anyway.)
