per-desc item.  Merge into one function since 'force_exact' is no longer
needed. (key_byname): Use new classify_user_id function, and new exact
flag in KEYDB_SEARCH_DESC.

* keyring.h, keyring.c (keyring_search): Return an optional index to show
which KEYDB_SEARCH_DESC was the matching one.

* keydb.h, keydb.c (keydb_search): Rename to keydb_search2, and pass the
optional index to keyring_search.  Add a macro version of keydb_search
that calls this new function.

* export.c (do_export_stream): If the keyid! syntax is used, export only
that specified key.  If the key in question is a subkey, export the
primary plus that subkey only.
