Subject: [PATCH] meson: use C99 as the standard

autoconf uses either C99 or Gnu99. Meson does not provide a graceful way
to select gnu99 if possible or c99 (though there are several proposals
currently happening to get there), so I've selected c99 as the
conservative default. Without this, the compiler uses whatever it's
default happens to be, which may or may not work out correctly, and
hides bugs from CI that are present with c99 as the default.
