These are momstly debugging tools for developers,
a bit documented in the header files (utils.h),
although more documentation is definitely necessary.
The performance impact is close to zero(*) so there is no
need to compile it conditionally.
(*) not completely true - thread destruction still needs
to search a list _but_ this can be easily optimized if we
end up with hundreds of active threads (in which case, though,
the problem is clearly elsewhere).

it doesn't report that all allocations are coming from utils.h. Also, add some
more information to the error message astmm reports when a memory allocation
failure occurs.

- attempt to log an error message if the __builtin_alloca inside of ast_strdupa
fails.
- document the fact that it is known and intended behavior for ast_strdupa to
cause Asterisk to crash if the alloca fails
- use __builtin_expect when checking for allocation failure in all of the
allocation wrappers
New Janitor Project! Anywhere that we check for a successful allocation after
a call to ast_strdupa is unnecessary and should be removed.

- Use a cleaner syntax for declaring the allocation macros
- Fix return value for ast_strdup/ast_strndup
- remove safe_strdup from app_macro, since ast_strup does the same thing
- fix a place in app_queue where ast_calloc+strncpy was used instead of
ast_strdup. If you are helping out with these conversions, please watch out
for other places where this is done.
- add a note to the coding guidelines about the fix to app_queue

add an automatically generated Asterisk log message if the allocation fails
for some reason. Otherwise, they are functionally the same, with the
exception of ast_strdup and ast_strndup. These functions have the added
ability to accept a NULL argument without error, which will just be ignored
without generating an error. The coding guidelines have also been updated to
reflect all of this information. (issue #4996)

convert chan_sip sip_pvt and sip_registry structures to use string fields
add 'const' qualifiers to a few API calls that don't modify their input strings
add an asprintf() wrapper to astmm

clean up some formatting
remove some commented out reference code
move unload_module in pbx_ael down to be with the rest of the standard module functions

make more LOW_MEMORY optimizations, and ensure that a non-inline version of each inlinable function is always available (for external modules)
move compiler-specific stuff into a separate header file

don't double-include pthread.h in utils.h, which can cause the
pthread_mutex_lock warning to not be generated on some systems
