Added a new pj_timer_entry_reset function that resets a timer_entry
for re-use.

Changed direct settings of timer_entry fields to use
pj_timer_entry_init and pj_timer_entry_reset.

Fixed issues where timers were being rescheduled incorrectly.

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
fetch was installed beforehand, although an explanation existed in code. This
happened because the code expected the variable DOWNLOAD_TO_STDOUT to be empty.
However, the script ./configure set that variable always.

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
and causing the session to be prematurely disconnected if a
transport error occurs immediately.

This change backports a fix from PJSIP that eliminates the
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
negotiated. According to RFC 3261 section 12.1.2 while a To tag is required,
the client needs to still be able to handle the missing tag case for
backwards compatibility.

This patch, accepted by and applied to pjproject, makes it so if an incoming
180/183 with SDP comes in without a To tag it gets appropriately handled.

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".

Parsing the numeric header fields like cseq, ttl, port, etc. all
had the potential to overflow, either causing unintended values to
be captured or, if the values were subsequently converted back to
strings, a buffer overrun.  To address this, new "strto" functions
have been created that do range checking and those functions are
used wherever possible in the parser.

 * Created pjlib/include/limits.h and pjlib/include/compat/limits.h
   to either include the system limits.h or define common numeric
   limits if there is no system limits.h.

 * Created strto*_validate functions in sip_parser that take bounds
   and on failure call the on_str_parse_error function which prints
   an error message and calls PJ_THROW.

 * Updated sip_parser to validate the numeric fields.

 * Fixed an issue in sip_transport that prevented error messages
   from being properly displayed.

 * Added "volatile" to some variables referenced in PJ_CATCH blocks
   as the optimizer was sometimes optimizing them away.

 * Fixed length calculation in sip_transaction/create_tsx_key_2543
   to account for signed ints being 11 characters, not 9.

'--with-pjproject-bundled' is now the default when running

To make building without an internet connection easier, a new
./configure option '--with-download-cache' was added that sets
the cache for externals (like pjproject, the codecs and the DPMA),
AND the sounds files.  It can also be specified as an environment
variable named "AST_DOWNLOAD_CACHE".  The existing
'--with-sounds-cache' option / SOUNDS_CACHE_DIR env variable and
'--with-externals-cache' option / EXTERNALS_CACHE_DIR env variable
remain and if specified, will override '--with-downloads-cache'.

OpenSSL has 2 levels or error processing.  It's possible for the
top layer to return SSL_ERROR_SYSCALL but the lower layer return
no error, in which case processing should continue.  Only the top
layer was being examined though so connections were being torn
down when they didn't need to be.  This patch adds the examination
of the lower level codes, and if they return no errors, allows
processing to continue.

When connected_line_method is "invite", we're supposed to determine
if the client can support UPDATE and if it can, send UPDATE instead
of INVITE to avoid the SDP renegotiation.  Not only was pjproject
not setting the PJSIP_INV_SUPPORT_UPDATE flag, we were testing
that invite_tsx wasn't NULL which isn't always the case.

* Updated chan_pjsip/update_connected_line_information to drop the
  requirement that invite_tsx isn't NULL.

After configuring Asterisk with '--with-pjproject-bundled' the configure/build
process attempts to download pjproject from its download site. Currently, a
timeout of 10 seconds is used that will stop the download process if pjproject
has not been fully downloaded in that time. For some systems this was not enough
time and the process was timing out too early.

This patch raises the download timeout value to '60'. Also, this patch fixes
another bug where the DOWNLOAD_TIMEOUT variable was not being properly exported
due to a naming error. DOWNLOAD_MAX_TIMEOUT is now properly renamed to
