(closes issue #12467)

Reported by: atis
Tested by: murf

This upgrade adds the ~~ (concatenation) string operator to expr2.
While not needed in normal runtime pbx operation, it is needed when
raw exprs are being syntax checked. This plays into future syntax-
unification plans. By permission of atis, this addition in trunk 
and the reason of why things are as they are will suffice to close
this bug.

I also added a short note about the previous addition of "sip show sched"
to the CLI in CHANGES, which I discovered I forgot in a previous commit.

   * Added a CLI command, "devstate change", which allows you to set custom device
      states from the func_devstate module that provides the DEVICE_STATE() function
      and handling of the "Custom:" devices.
+  * New CLI command: "sip show sched" which shows all ast_sched entries for sip,
+    sorted into the different possible callbacks, with the number of entries
+    currently scheduled for each. Gives you a feel for how busy the sip channel
