Update and clean up autoconf template files.

This is needed for compatibility with newer autoconf:
* Removed macro GINAC_STD_CXX_HEADERS (we use AX_CXX_COMPILE_STDCXX).
* Updated m4/* files from upstream.
* Ran autoupdate on acinclude.m4 and configure.ac.

Tested successfully with autoconf 1.69 and 1.71.
acinclude.m4
