Subject: [PATCH] obexd: Add messages backend initialization and finalization

This adds functions for initializing and freeing resources used by
message storage access backend and example implementation in the dummy
(or rather - filesystem) backend.

Dummy backend uses $MAP_ROOT (if set) and falls back to
$HOME/map-messages for its message storage. This directory should at
least contain basic folders required by the MAP specification. It
represents the root as seen from the perspective of MAP client. You can
prepare it as follows:

$ mkdir -p "$MAP_ROOT/telecom/msg/inbox"
$ mkdir "$MAP_ROOT/telecom/msg/sent"
$ mkdir "$MAP_ROOT/telecom/msg/deleted"
$ mkdir "$MAP_ROOT/telecom/msg/outbox"
