configure.ac: rewrite WARN_CFLAGS initialization
As the old machinery was not prepared for adding compiler options
conditionally when the compiler supports them, replace it with
a new machinery that implements this.
* m4/warnings.m4: New file.
* m4/warn_lang_flags.m4: Likewise.
* m4/.gitignore: Add exclusions for them.
* m4/japhar_grep_cflags.m4 (JAPHAR_GREP_CFLAGS): Remove.
* configure.ac: Call pam_WARN_LANG_FLAGS. Remove all uses
of JAPHAR_GREP_CFLAGS.
