Re-indentation of keydb.c and error code changes.

2011-04-29 Werner Koch <wk@g10code.com>
* keydb.c (keydb_get_keyblock, keydb_add_resource): Use gpg_error.
(keydb_get_keyblock): Return VALUE_NOT_FOUND instead of -1.
(keydb_update_keyblock, keydb_insert_keyblock)
(keydb_delete_keyblock): Ditto.
(keydb_locate_writable): Ditto.
(keydb_search_reset): Ditto.
(keydb_search2): Return GPG_ERR_NOT_FOUND instead of -1. Change
all callers.
(keydb_search_first, keydb_search_next, keydb_search_kid)
(keydb_search_fpr): Ditto.
2011-04-28 Werner Koch <wk@g10code.com>
* ecdh.c (pk_ecdh_encrypt_with_shared_point): Remove memory leak
