Search for items matching the @attributes in the @collection.
The @attributes should be a table of string keys and string values.
If %SECRET_SEARCH_ALL is set in @flags, then all the items matching the
search will be returned. Otherwise only the first item will be returned.
This is almost always the unlocked item that was most recently stored.
If %SECRET_SEARCH_UNLOCK is set in @flags, then items will be unlocked
if necessary. In either case, locked and unlocked items will match the
search and be returned. If the unlock fails, the search does not fail.
If %SECRET_SEARCH_LOAD_SECRETS is set in @flags, then the items will have
their secret values loaded and available via secret_item_get_secret().
This function may block indefinitely. Use the asynchronous version
in user interface threads.
