This patch is not in the upstream pjproject and does unsafe things with
the timer->_timer_id and timer->_grp_lock values in pj_timer_entry_reset()
outside of the timer heap lock.  pj_timer_entry_reset() is also called for
timers that are not about to be rescheduled in a few places.

When writing an RTCP report to json the code attempts to pack the "ssrc" and
"source_ssrc" unsigned integer values as a signed int value type. This of course
means if the ssrc's unsigned value is greater than that which can fit into a
signed integer value it gets converted to a negative number. Subsequently, the
negative value goes out in the json report.

This patch now packs the value as a json_int_t, which is the widest integer type
available on a given system. This should make it so the value no longer
overflows.

Note, this was caught by two failing tests hep/rtcp-receiver/ and
hep/rtcp-sender.

The script configure from Teluu expects shared libraries (.so) in a subfolder
called 'lib', when --with-xyz=PATH is specified. However for OpenSSL, the
default location is the root of the source folder = PATH. Furthermore, Asterisk
supports both, 'lib' and root. For consistency and because Asterisk is using
(only) OpenSSL in PJProject, it is enhanced to support both locations, just
like Asterisk.

Changing any Menuselect option in the `Compiler Flags` section causes a
full rebuild of the Asterisk source tree.  Every enabled option causes
a #define to be added to buildopts.h, thus breaking ccache caching for
every source file that includes "asterisk.h".  In most cases each option
only applies to one or two files.  Now we only define those options for
the specific sources which use them, this causes much better cache
matching when working with multiple builds.  For example testing code
with an without MALLOC_DEBUG will now use just over half the ccache
size, only main/astmm.o will have two builds cached instead of every
file.

Reorder main/Makefile so _ASTCFLAGS set on specific object files are all
together, sorted by filename.  Stop adding -DMALLOC_DEBUG to CFLAGS of
bundled pjproject, this define is no longer used by any header so only
serves to break cache.

The only code change is a slight adjustment to how main/astmm.c is
initialized.  Initialization functions always exist so main/asterisk.c
can call them unconditionally.  Additionally rename the astmm
initialization functions so they are not exported.

Asterisk patched the pjproject source to avoid crashing when pjproject
sip_msg headers are encountered with NULL vptr's, but the patch also
output error messages for some valid headers which simply did not need
to be added to the message itself, such as hidden route headers.

pjproject has since applied a similar patch to their baseline to avoid
crashes, but their version also avoids the spurious error logging.

Lets use their patch instead.

Asterisk modules that use PJPROJECT services have their compiler
optimization and possibly their symbolic debug options overridden by the
PJPROJECT configure script selected settings.

* We need to filter-out any -O and -g options in PJ_CFLAGS before echoing

Asterisk module settings when using bundled PJPROJECT.

pjproject by default currently will follow media forked during an INVITE
on outbound calls if the To tag is different on a subsequent response as
that on an earlier response.  We handle this correctly.  There have
been reported cases where the To tag is the same but we still need to
follow the media.  The pjproject patch in this commit adds the
capability to sip_inv and also adds the capability to control it at
runtime.  The original "different tag" behavior was always controllable
at runtime but we never did anything with it and left it to default to
TRUE.

So, along with the pjproject patch, this commit adds options to both the
system and endpoint objects to control the two behaviors, and a small
logic change to session_inv_on_media_update in res_pjsip_session to
control the behavior at the endpoint level.

The default behavior for "different tags" remains the same at TRUE and
the default for "same tag" is FALSE.

There have been some crashes in the past where something attempts
to use a pj_atomic after it's already been destroyed.  This patch
tries to prevent it by making sure that pj_atomic_destroy sets
its mutex to NULL when it's done.  The pj_mutex functions already check
for a NULL mutex and just return PJ_EINVAL.

Teluu also added some checks to the win32 implementation as well.

./configure --with-pjproject-bundled
did not display an explanation, when no download utility like wget, curl, or

This replaces AST_INLINE_API allocators in utils.h with real functions
implemented in astmm.c.  Associated macro's are also moved from utils.h
to astmm.h.

Remove menuselect conflicts between MALLOC_DEBUG and DEBUG_CHAOS as they
can now be combined.

This has multiple benefits:
* Simplifies asterisk/utils.h by removing inline functions and use of
  the logger.
* Removal of these inline functions decreases size of Asterisk and
  module binaries by 1% or more.
* Puts memory management functions together with and without
  MALLOC_DEBUG enabled, simplifying management of the code.
* Enables DEBUG_CHAOS for ASTMM_REDIRECT and bundled pjproject.

When an older GCC version is called with a too new warning option, GCC exited
with an error and Asterisk was not built. Therefore, the configure script tests
the installed compiler whether it supports that warning option. If not, Asterisk
does not pass it to the installed compiler. However, some compilers (like clang)
do not exit (error) but give just a warning in such a case. Because the compiler
did not exit, Asterisk passed the unknown-warning option.

When we fail over to a new target we create a new transaction
and it becomes the current INVITE transaction. This does not
prevent the previous transaction from raising state changes

incorrect state change and reduces when they would be raised
in the first place.

If a 183 with sdp response is receive without a To tag the sdp is not

If a transport is created with the same transport type, source
IP address, and source port as one that already exists the old
transport is moved into a linked list called "tp_list".

If this old transport is later shutdown it will not be destroyed
as the process checks whether the transport is valid or not. This
check does not look at the "tp_list" when making the determination
causing the transport to not be destroyed.

This change updates the logic to query not just the main storage
method for transports but also the "tp_list".
