Do not require Mailutils. Provide missing functions.

(AC_CONFIG_FILES): Add new subdirs. * gnulib.modules: Add more modules. Arrange entries alphabetically. * lib/Makefile.am: Rename library to libpies. * lib/libpies.h (mf_privs) (switch_to_privs, get_user_groups) (mf_priv_setup, mf_epriv_setup): Move to src/pies.h (config_array_to_argv, config_array_to_string) (config_cb_timeout): Remove. (tokendef): New struct. (strtotok_len, strtotok_len_ci) (strtotok, strtotok_ci, toktostr): New prototypes. * lib/nls.c: Remove call to mu_init_nls. * src/acl.c: New file. * src/addrfmt.c: New file. * src/diag.c: New file. * src/meta.c: New file. * src/url.c: New file. * src/userprivs.c: New file. * src/acl.h: New file. * src/pp-setup: New file. * src/Makefile.am (pies_SOURCES): Add acl.c, addrfmt.c, diag.c, meta.c, url.c, userprivs.c. (noinst_HEADERS): Add acl.h. (inc_DATA): Add pp-setup. * src/limits.c, src/meta1gram.y, src/meta1lex.h, src/meta1lex.l, src/pies.c, src/pies.h, src/progman.c, src/socket.c, src/userprivs.c: Remove calls to functions from Mailutils.
