FS-7635: remove msvc 2005 2008 and 2010 non working build systems.  There are now multiple more recent (3 different ones) and some free versions of the compiler that can be used.

FS-7622 make sure to close the connections on destroy. Currently the connection is malloc'd from the module pool, so there is nothing to destroy.

Merge pull request #156 in FS/freeswitch from ~ITALOROSSI/freeswitch:FS-7138-mod_callcenter_reserve_agent_before_dialing to master

* commit 'bebd4c4e':
  FS-7138 - new mod_callcenter param: reserve-agents

Sets the agent state to Reserved before calling him. In this case,
the Agent is first updated to state Reserved ONLY if his previous
state was Waiting and status was Available/Available (On Demand).
The purpose is to avoid possible race conditions when external
applications are manipulating `agents` table.

Disabled by default.

* commit 'b7e70bf1':
  FS-7612: callflow section in json_cdr as array.

Updated SKINNY on-hook action to hang up all calls on a device, except those in a short list of call states (or perform a blind transfer).
Added a hook after completing the hangup operation to start ringing if there is an inbound call active on the device.
