Improved URI parser that keeps track of the path information and doesn't
modify the input string. (keyserver_spawn): Tell keyserver plugins about
the path.
preferred keyserver on "keyserver" command line. Sanity check keyserver
URL before accepting it.
* keyserver-internal.h, g10.c (main), keyserver.c (parse_keyserver_uri):
Add an option to require the scheme:// and change all callers.
(free_keyserver_spec): Make public.
and properly handle a partial match against an option with an argument.
* keyserver-internal.h, keyserver.c (parse_keyserver_options): Use new
optsep and argsplit functions.
keyserver.c (parse_keyserver_uri): Parse keyserver URI into a structure.
Cleanup for new "guess my keyserver" functionality, as well as refreshing
via a preferred keyserver subpacket.
show_prompt, keyserver_search_prompt, keyserver_spawn): Go to version 1 of
the keyserver protocol. This is a better design, similar to
--with-colons, that allows for keys with multiple user IDs rather than
using multiple keys. It also matches the machine readable pksd format.
Also use a prettier --search-keys listing format that can fill different
size windows (currently set at 24 lines).
