* This quick update fixes build failures in libfontenc 1.1.5 on
platforms that require setting a #define such as _GNU_SOURCE,
_OPENBSD_SOURCE, or __EXTENSIONS__ to expose the reallocarray()
prototype in their headers.

* Fix spelling/wording issues
* gitlab CI: add a basic build test
* Import reallocarray() from libX11 (originally from OpenBSD)
* Convert code to use Xmallocarray() & Xreallocarray()
* configure: Use AC_USE_SYSTEM_EXTENSIONS to set GNU_SOURCE & other defines
