Rewrite Makefile rules for lex and bison

The aim is to get rid of the explicit rules and use the Autmake framework
as much as possible, without hurting the flexibility.  To this effect, the
gylwrap tool is rewritten from scratch (in Perl).  In compatibility
mode it takes the same arguments as the standard ylwrap.  Additional
configuration is supplied in the configuration file gylwrap.conf, located
in the directory where the input file resides.

* mu-aux/gylwrap: Rewrite from scratch.
* configure.ac (MU_YLWRAP): New subst variable.
* libmailutils/base/.gitignore: Update.
* libmailutils/base/Makefile.am: Update.
* libmailutils/base/gylwrap.conf: New file.
* libmailutils/cfg/.gitignore: Update.
* libmailutils/cfg/Makefile.am: Use new YLWRAP
* libmailutils/cfg/cfg.h: Remove.
* libmailutils/cfg/gylwrap.conf: New file.
* libmailutils/cfg/lexer.l: Include mailutils/yyloc.h directly.
* libmailutils/cfg/parser.y: Likewise.
* libmu_sieve/Makefile.am: Use new YLWRAP
* libmu_sieve/gylwrap.conf: New file.
* libmu_sieve/sieve.y: Rename to libmu_sieve/sieve-gram.y
* libmu_sieve/sieve.l: Rename to libmu_sieve/sieve-lex.l
* mail/Makefile.am: Use new YLWRAP
* mh/.gitignore: Update.
* mh/Makefile.am: Use new YLWRAP
* mh/gylwrap.conf: New file.
* mh/mh_alias.y: Rename to mh/mh_alias_gram.y
* mh/mh_alias.l: Rename to mh/mh_alias_lex.l
* mh/pick.y: Rename to mh/pick-gram.y
* mimeview/.gitignore: Update.
* mimeview/Makefile.am: Use new YLWRAP
* mimeview/mimetypes.y: Rename to mimeview/grammar.y
* mimeview/gylwrap.conf: New file.
* mimeview/mimetypes.l: Rename to mimeview/lexer.l
* po/POTFILES.in: Update
