Add framework for code style- and syntax-checking rules. Almost all tests are initially disabled via the list in Makefile.cfg. * Makefile.am (EXTRA_DIST): Add .x-sc_avoid_if_before_free. Omit names of files that automake includes automatically. * .x-sc_avoid_if_before_free: New file. * build-aux/vc-list-files: Likewise. * build-aux/find-unnecessary-if-before-free: Likewise. * GNUmakefile, Makefile.cfg, Makefile.maint: New files.
