* getkey.c (merge_keys_and_selfsig): Divert merging of public keys
to the function used in key selection..
* keylist.c (is_uid_valid): Removed.
(list_keyblock): Splitted into ..
(list_keyblock_print, list_keyblock_colon): .. these.
functions. Changed them to use the flags set in the key lookup code.
(reorder_keyblock): New, so that primary user IDs are listed first.
* ringedit.c (keyring_copy): flush the new iobuf chaces before
rename or remove operations. This is mainly needed for W32.
