Rewrite configuration parser, drop dependency on GSC

* bootstrap: Replaced with a modified version from gnulib.
* configure.ac: Bump version to 1.9.90
(--without-preprocessor): New option
Require Mailutils 2.0
(AC_CONFIG_FILES): Remove lib, add gconf

* gconf/: New directory. Contains general-purpose configuration file
parser, distilled from Dico and Mailutils.

* src/Makefile.am (wydawca_SOURCES): Add interval.c
* src/pp-setup, src/update-2.0.awk: New files.
* src/config.c: Full rewrite.
* src/exec.c (start_prog): Use getdtablesize unconditionally.
* src/mail.c: Keep templates in a hash table.
Template references begin with a single @
* src/process.c, src/triplet.c, src/verify.c: Reflect changes to struct
directory_pair

* src/wydawca.c: Change configuration parsing.
* src/wydawca.h (enum access_method_id): New constants
(struct directory_pair): Replace four access methods with an array.

* Makefile.am (SUBDIRS): Remove lib, add gconf
* .gitignore, NEWS, doc/.gitignore, src/.gitignore
