Subject: [PATCH] Remove HAVE_STRING_H, HAVE_STDARG_H, and HAVE_STDLIB_H

These symbols are defined by the build system to check the presence of
the standard C89 headers. Since C89 is really widely adopted across
systems already, these checks are obsolete today and not needed.

http://port70.net/~nsz/c/c89/c89-draft.html#4.1.2

Some of these checks are also removed since PHP-7.4.
