Use it here for the various notation commands.
* packet.h, main.h, keygen.c (keygen_add_notations), build-packet.c
(string_to_notation, sig_to_notation) (free_notation): New "one stop
shopping" functions to handle notations and start removing some code
duplication.
pka-lookups, not pka-lookup.
* options.h, gpg.c (main), keyedit.c [cmds], sig-check.c
(signature_check2): Rename "backsign" to "cross-certify" as a more
accurate name.
(check_signatures_trust), mainproc.c (check_sig_and_print,
pka_uri_from_sig), trustdb.c (init_trustdb): Some tweaks to PKA so that it
is a verify-option now.
--no-auto-key-locate.
* options.h, gpg.c (main): Keep track of each keyserver registered so
we can match on them later.
* keyserver-internal.h, keyserver.c (cmp_keyserver_spec,
keyserver_match), gpgv.c: New. Find a keyserver that matches ours and
return its spec.
* getkey.c (get_pubkey_byname): Use it here to get the per-keyserver
options from an earlier keyserver.
when fetching a URI.
* keyserver-internal.h, keyserver.c (keyserver_fetch): New. Fetch an
arbitrary URI using the keyserver helpers.
* gpg.c (main): Call it from here for --fetch-keys.
since we may unprotect it.
* main.h, g10.c (main), revoke.c (gen_desig_revoke): Add local user
support so users can use -u with --desig-revoke. This bypasses the
interactive walk over the revocation keys.
speaking this should be only in gpg_CPPFLAGS, but then we have to
compile everything twice for gpg and gpgv.
* apdu.c (open_pcsc_reader): Fix double free.
* gpg.c (main) [__APPLE__]: Default the PCSC driver to the OS X
location. Suggested by Patty A. Hardy.
