If a deadlock is detected, then the typical lock information will be
printed along with a backtrace of the stack for the offending threads.
Use of this requires compiling with DETECT_DEADLOCKS and having glibc
installed.
Furthermore, issuing the "core show locks" CLI command will print the
normal lock information as well as a backtraces for each lock. This
requires that DEBUG_THREADS is enabled and that glibc is installed.
All the backtrace features may be disabled by running the configure
script with --without-execinfo as an argument

Until this change, all verbose messages in Asterisk's log files reported logger.c
as the source of the message.

so compilers that don't understand that this code is NOTREACHED
will not complain (the fault is not much on the compiler but on the
declaration of pthread_exit on certain platforms)
s/certain platform/cygwin/ if you are really curious

build times - tested, there is no measureable difference before and
after this commit.
In this change:
use asterisk/compat.h to include a small set of system headers:
inttypes.h, unistd.h, stddef.h, stddint.h, sys/types.h, stdarg.h,
stdlib.h, alloca.h, stdio.h
Where available, the inclusion is conditional on HAVE_FOO_H as determined
by autoconf.
Normally, source files should not include any of the above system headers,
and instead use either "asterisk.h" or "asterisk/compat.h" which does it
better.
For the time being I have left alone second-level directories
(main/db1-ast, etc.).

ao2_callback() is a much more efficient way of performing an operation on every
item in the container. This change makes hashtest2 run in about 25% of the
time it ran before on my system.
In general, I would say that it makes the most sense to use an ao2_iterator if
the operation being performed is going to take a long time and you don't want
to keep the container locked while you work with each object. Otherwise,
the use of ao2_callback is preferred.
