Subject: [PATCH 125/127] CACHE_REQ_RESULT: Introduce
 cache_req_create_ldb_result_from_msg_list()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Similarly to what cache_req_create_ldb_result_from_msg() does this new
function creates a new ldb_result from a list of ldb_message.

It's going to be used in the follow-up patch where some messages from
ldb_result may be filtered and then a new ldb_result has to be created.
