Re: [sr-dev] [kamailio/kamailio] mqueue: add support for db persistency (#2359)

Code patch looks ok, maybe some small cosmetic adjustments can be done later (e.g., vars declared at the beginning of blocks), so can be merged from that point of view. But there are some changes to file permissions, adding executable flag:

``` mode change 100644 => 100755 src/modules/mqueue/Makefile mode change 100644 => 100755 src/modules/mqueue/README mode change 100644 => 100755 src/modules/mqueue/api.h mode change 100644 => 100755 src/modules/mqueue/mqueue_api.c mode change 100644 => 100755 src/modules/mqueue/mqueue_api.h create mode 100755 src/modules/mqueue/mqueue_db.c create mode 100755 src/modules/mqueue/mqueue_db.h mode change 100644 => 100755 src/modules/mqueue/mqueue_mod.c ```

Which should not be needed.
