Fix lock errors on startup.
In messages.c, there are several places in the code where we create a
tmp_tech_holder and pass that into an ao2_find call. Unfortunately, we
weren't initializing the rwlock on the tmp_tech_holder, which the hash
function was locking. It's apparently harmless, but still not the best
code.
This patch extracts all that copy/pasted code into two functions,
msg_find_by_tech and msg_find_by_tech_name, which properly initialize
and destroy the rwlock on the tmp_tech_holder.

Allow WebSocket connections on more URL's
This patch adds the concept of ast_websocket_server to
res_http_websocket, allowing WebSocket connections on URL's more more
than /ws.
The existing funcitons for managing the WebSocket subprotocols on /ws
still work, so this patch should be completely backward compatible.

Create the basic bridge subclass of struct ast_bridge.
This bridge class is the normal bridge for most calls. It adds management
of the DTMF feature hooks for each channel while they are in this bridge.
When the basic two party bridge expands into a multi-party bridge, the
various parties can drop out of the bridge without destroying it.
The new bridging API does not allow casual knowledge of what channels are
bridged with a particular channel because there can be more than one.
With this restriction, the support of the [applicationmap] ActivatedBy
feature option no longer makes sense and cannot be supported. The
ActivatedBy option is now just ignored. The feature can only be activated
by the channel it is attached to and not by its peer.

Prevent res_timing_pthread from blocking callers
There were several reports of deadlock when using
res_timing_pthread. Backtraces indicated that one thread was blocked
waiting for the write to the pipe to complete and this thread held
the container lock for the timers. Therefore any thread that wanted
to create a new timer or read an existing timer would block waiting
for either the timer lock or the container lock and deadlock ensued.
This patch changes the way the pipe is used to eliminate this source
of deadlocks:
1) The pipe is placed in non-blocking mode so that it would never
block even if the following changes someone fail...
2) Instead of writing bytes into the pipe for each "tick" that's
fired the pipe now has two states--signaled and unsignaled. If
signaled, the pipe is hot and any pollers of the read side
filedescriptor will be woken up. If unsigned the pipe is idle. This
eliminates even the chance of filling up the pipe and reduces the
potential overhead of calling unnecessary writes.
3) Since we're tracking the signaled / unsignaled state, we can
eliminate the exta poll system call for every firing because we know
that there is data to be read.

sla: remove redundant locking.
sla.lock was already locked in the only place that sla_check_reload() was called.
Remove the redundant locking of sla.lock done in this function. Less recursive

This patch adds a RESTful HTTP interface to Asterisk.
The API itself is documented using Swagger, a lightweight mechanism for
documenting RESTful API's using JSON. This allows us to use swagger-ui
to provide executable documentation for the API, generate client
bindings in different languages, and generate a lot of the boilerplate
code for implementing the RESTful bindings. The API docs live in the
rest-api/ directory.
The RESTful bindings are generated from the Swagger API docs using a set
of Mustache templates. The code generator is written in Python, and
uses Pystache. Pystache has no dependencies, and be installed easily
using pip. Code generation code lives in rest-api-templates/.
The generated code reduces a lot of boilerplate when it comes to
handling HTTP requests. It also helps us have greater consistency in the
REST API.

Fix crash when AMI redirect action redirects two channels out of a bridge.
The two party bridging loops were changing the bridge peer pointers
without the channel locks held. Thus when ast_channel_massquerade()
tested and used the pointer there is a small window of opportunity for the
pointers to become NULL even though the masquerade code has the channels
locked.

Get local channel optimization working again using the new bridging model.
The primary method of optimization is to merge bridges together. The
optimizing local channels continuously check for empty queues in the
local;1 and local;2 channels. Once it is found that the queues are empty
and the bridges allow merging, either BridgeA or BridgeB is merged into
the other bridge.
A future additional way to optimize out local channels in more
circumstances is to swap the Local;2 channel in BridgeB with the only peer
channel (A) in BridgeA. This optimization strategy would be needed if
BridgeB prohibits bridge merges.
A -- BridgeA -- Local;1-Local;2 -- BridgeB -- B
