sensitive revkeys along with the revocation sig itself.
* keyserver.c (parse_keyserver_options): Simpler implementation that can
skip one pass over the options.
designated revoker means "sensitive", not "local". It's exportable under
the right circumstances.
* main.h, options.h, export.c (do_export_stream), g10.c (main), hkp.c
(hkp_export), keyserver.c (keyserver_spawn: Add a flag to skip attribute
packets and their signatures while exporting. This is to accomodate
keyservers (pksd again) that choke on attributes. Use keyserver-option
"include-attributes" to control it. This defaults to ON (i.e. don't
skip).
keyserver_work), hkp.c (hkp_ask_import, hkp_export, hkp_search): Use a
much more strict reading of RFC-2396 for the keyserver URIs. Specifically,
don't try and be smart about checking the value of ":port" so long as it
is all digits, and properly handle opaque data (those scheme specific
parts that do not start with "//").
FIXED_PHOTO_VIEWER and DISABLE_PHOTO_VIEWER.
* mainproc.c (check_sig_and_print): Use --show-photos to show photos when
verifying a sig made by a key with a photo.
* keyserver.c (parse_keyserver_uri): Properly parse a URI with no :port
section and an empty file path, but with a terminating '/'.
(keyserver_work): Honor DISABLE_KEYSERVER_HELPERS.
* hkp.c (hkp_ask_import): Display keyserver URI as a URI, but only if
verbose.
* exec.c, g10.c: USE_EXEC_PATH -> FIXED_EXEC_PATH
use the original keyserver URI for cosmetics rather than trying to
recreate it when needed.
* mainproc.c (check_sig_and_print): Properly disregard expired uids.
Make sure that the first uid listed is a real uid and not an attribute
(attributes should only be listed in the "aka" section). When there are
no valid textual userids, try for an invalid textual userid before using
any attribute uid.
