Expose the queue_mut for external users.
Supposed to only be used with a snapshot mechanism,
because it is partially a data incapsulation violation.
The container itself and lock mechanism is meant
to be reworked in the future, to not expose locks anymore.

A a mechanism to get the AmSession object
stored polymorphically on the EvQueueMap.
Follow the classes hierarchy:
AmEventQueueInterface -> AmEventQueue -> AmSession
to retrieve AmSession by down casting it from base class.
When retrieved, acquire the snapshot dedicated lock
to prevent other thread destroying this gotten AmSession.
As soon as AmSessionSnapshot is ready,
release the lock and let other (real owner) thread do anything with it.
Left corner cases:
- by the time the AmEventQueueInterface is retrieved and down-casted
into the AmSession, returned to the user and the snapshot lock
is acquired, this thread can simply destroy the AmSession object
- this is an undefined behavior

Use static_cast for the up-cast of AmSession.
Static cast is equivalent to the C-style implicit cast,
when doing an up-cast, but C-style cast is less clear.
So just use static_cast here.

Create the unique pointer based on the AmSession raw
pointer right away and assign, instead of doing
separately the declaration and initialization.

To make the Coverity Scan happy and also
make the code a bit more excplicit in terms of
managing the ownership over the session in
(`startSessionUAS()` and `startSessionUAC()`)
just add a code commentary describing what's going on.
Change-Id: I6383c50bf99cbacc29cd77085b787c51bdbee039
startSessionUAC():
Move the session smart pointer into the try statement,
on the same manner as done in `startSessionUAS()`.

Make it using spaces, instead of the EMACS based
tabulation/space combination, which makes it
messy for modern IDEs.

When building up the AmSession and assigning
the app parameters to it, do the move operation

Update the AmArg argument to const as these functions never change it,
and it may come from a const source. (The `string` counterpart in the
other overload is already const qualified.)

C++20 deprecates implicit conversion of enumerations
during math operations like division.
Instead deprecate enum CPS_SAMPLERATE which is used
in a role of pre-proc definition and add a `const float`
value of which is defined by the constructor and is
unchangable.
Also don't use straight-forward (old style) cast with `(<type>)`
but use C++ designed type casts like a static cast, for the
rest of operands in the formula.

Eliminate the `auto_ptr` usage for core/* ,
since this pointer type has been deprecated in C++11.
Use, as recommended, `unique_ptr` instead.

Remark: this commit is created as an attempt to keep PRO / CE sems repositories
consistent in terms of the provided code and functionality.
We need to have a possibility to detect emergency calls and let them
pass through the SEMS, even if the license limitation (CPSLimit) is triggered.
Also taking into account the global policy defined by the cfg parameter
'skip_cpslimit_emergency'.
If set to 'yes' (in the code will be treated as True)
then we do not drop emergency calls on CPSLimit triggering.
If set to 'no' - we treat emergency calls
as if they were usual calls in terms of checking CPSLimit license limitation.

If an INVITE has been forked and more than one branch is aimed at SEMS,
then the branch parameter of the top-via is necessary to distinguish the
different sessions.
By default, SEMS will now accept forked INVITEs.
This behavior can be switched off by setting "accept_forked_dialogs" to "no" (default=yes).
Conflicts:
core/AmSipDispatcher.cpp
- the session pointer should not be touched after the session has been started (could be immediately destroyed).
- return 481 on CANCEL if the transaction cannot be found.
- reply properly with 482 if the UAS dialog already exists.
SIGHUP - broadcast shutdown, usually sends BYE and stops all calls. The server does not terminate.
SIGINT - broadcast shutdown (usually sends BYE and stops all calls), and stop.
SIGTERM - stop the server, without broadcasting shutdown (no BYEs sent).
to prevent SEMS from stopping if there are hanging sessions,
a limit on the maximum shutdown time (actually time to wait
for sessions to stop) can be configured
default: 10 seconds
turn off by setting to 0
to use it, set USE_THREADPOOL in Makefile.defs and configure thread pool
size with session_processor_threads= parameter in sems.conf :
+# compile with session thread pool support?
+# use this for very high concurrent call count
+# applications (e.g. for signaling only)
+# if compiled with thread pool, there will be a
+# thread pool of configurable size processing the
+# signaling and application logic of the calls.
+# if compiled without thread pool support, every
+# session will have its own thread.
+#
+#USE_THREADPOOL = yes

- active sessions and other event receivers
get a SystemEvent::ServerShutdown,
default behaviour of AmSession is setStopped()
- session container waits for all sessions to be ended
- signaling server, rtp receiver, media processor, event dispatcher
are stopped and deleted

- removed AmSIPEventHandler (its functionalities are now in AmEventDispatcher).
- added possibility for each plug-in to receive out-of-dialog messages (any kind).
- added possibility to handle dialogs without creating a session (=AmSession).
