gpg: Allow selecting subkeys using a keyid.

Browse Source 
* g10/keyedit.c (menu_select_key): Take an additional argument, p.
Update callers.  If P is a hex string, then assume that P is a key id
or fingerprint and select subkeys with matching key ids or
fingerprints.
* doc/gpg.texi: Update documentation for the key subcommand.
