callcenter_break agent <uuid> can be called with an uuid that represents
an outbound session created to call an agent.

The current behavior of mod_callcenter is to keep watching this channel
until it is hangup, once the hangup happens the bridge-agent-end and
member-queue-end events are fired, agent is released on the database
so it can receive more calls and member is also updated on database.

If you do not want to the agent channel hangup to release the agent you can
call this app with the agent session uuid and the agent will be released and
available to receive more calls. This is useful when the agent is located on a
remote freeswitch box and transfer the call internally, the original leg between
the first FreeSWITCH and the remote box remains live and the agent will only be
Available when the original call hangup.

FS-10167: Temporary commit to retain changes before removing concept of realm/subrealm as per discussions, will revisit this concept later when a real use-case presents itself, tests will not operate correctly in this build as realms are incomplete prior to removal

  FS-10617: [mod_sofia] Nightmare transfer: expose remote server's channel UUIDs as variables.

FS-10167: Added support for SSL/TLS, specifically enforcing TLS 1.2 currently but could be more configurable later.  Added support for obtaining SANS from X509 certificates within the default wss transport, SANS will be used for preapproved automatically registered identities, currently only being cached on server side for downstream connections providing the remote client upstream certificate SANS, but can also be used by a master to obtain initial master identities from it's own downstream certificate in the future (planned, but not yet implemented) as it is the exception with no upstream and MUST have downstream available. Also added the openssl executable to the projects being built in the libblade solution to provide a windows executable for certificate production when required.

FS-10613: [core] freeswitch using the the wrong PT value (using the transmit PT instead of the receive PT) #resolve

FS-10637: [core] FreeSWITCH crash in 'enterprise originate' API caused due to fix done for FS-10596  #resolve

Currently there is no easy way for ESL and dial plan users to easily correlate
the channel UUID of the call legs involved in a nightmare transfer. This patch
adds two new channel variables, which are set to the remote server call leg
UUIDs (transfer_refer_from, transfer_refer_for).

The UUIDs are passed from the remote server in custom headers (X-FS-Refer-From
and X-FS-Refer-For).
