Implement MM_PREREQ() Autoconf macro
* macros/mm-common.m4.in: New configure input file.
(_MM_PRE_INIT): Move macro from mm-module.m4 to mm-common.m4.
(MM_PREREQ): Implement a version check macro akin to AC_PREREQ() and
similar macros. This may be used to ensure the presence of a minimum
version of the mm-common package at the time the configure script is
generated, should the need ever arise.
* configure.ac (AC_CONFIG_FILES): Add output file macros/mm-common.m4.
* Makefile.am (aclocal_macro_DATA): Install macros/mm-common.m4.
