  1. meson: Move C99 test earlier 

    That way, if any command-line options are needed, subsequent tests
will also use them.

  2. Raise C requirement to C11 

    This changes configure and meson.build to require at least C11,
instead of the previous C99.  The installation documentation is
updated accordingly.

configure.ac previously used AC_PROG_CC_C99 to activate C99.  But
there is no AC_PROG_CC_C11 in Autoconf 2.69, because it's too
old.  (Also, post-2.69, the AC_PROG_CC_Cnn macros were deprecated and
AC_PROG_CC activates the last supported C mode.)  We could update the
required Autoconf version, but that might be a separate project that
no one wants to undertake at the moment.  Instead, we open-code the
test for C11 using some inspiration from later Autoconf versions.  But
instead of writing an elaborate test program, we keep it simple and
just check __STDC_VERSION__, which should be good enough in practice.

In meson.build, we update the existing C99 test to C11, but again we
just check for __STDC_VERSION__.

This also removes the separate option for the conforming preprocessor
on MSVC, added by commit 8fd9bb1, since that is activated
automatically in C11 mode.

Note, we don't use the "official" way to set the C standard in Meson
using the c_std project option, because that is impossible to use
correctly (see <mesonbuild/meson#14717>).
