  FS-9011 [avmd] Add XML config

This is a generated file that was added by commit:

    commit 77f52bb6
    "FS-7928 FS-7618 systemd and package build improvements"

We were missing mod_smpp; mod_json_cdr needed to be placed differently
in the file such that it matches the output of the automated generator
we use to check the completeness of this file.

Add XML configuration file.
Bind reloadxml callback.
Add safe parsers of user's input.
Add show/set/load/reload API commands.

* commit 'b024c752':
  FS-9093: mod_cv: remove unneeded includes

OpenCV contains various modules which have inter-module dependencies.
While including freeswitch into buildroot we stumbled over the fact
that mod_cv.cpp includes more headers than needed[1].
hese OpenCV headers are generic headers which require more OpenCV
modules enabled than really used by Freeswitch.
This patch fixes the problem.
