gpg: Take care of keydb_new returning NULL.

Browse source 
* g10/keydb.c (keydb_new): Print an error message if needed.  Also use
xtrycalloc because we return an error anyway.

keydb_new.

* g10/t-keydb.c (do_test): Ditto.

* g10/keyring.c (keyring_new): Actually return an error so that the
existing keydb_new error checking makes sense for a keyring resource.
(keyring_rebuild_cache): Take care of keyring_new returning an error.

Commit 04a6b903 changed keydb_new to return an error.  However the
error was not checked at most places which we fix with this patch.  To
make things easier keydb_new prints an error message itself.

file handle: it contains a local file position. This is used when
searching: subsequent searches resume where the previous search
left off. To rewind the position, use keydb_search_reset(). This
function returns NULL on error, sets ERRNO, and prints an error
diagnostic. */
