* keyedit.c (keyedit_menu, menu_set_keyserver_url): Allow passing

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.
