new-style modules using static symbols.
Everything will still work as before, but new-style modules
can now be defined by putting a '#define STATIC_MODULE' somewhere
before including module.h, then declaring STATIC_MODULE the
various methods (load, unload, key...) that the module is
supposed to supply, and adding a 'STD_MOD(MOD_1, reload_fn, NULL, NULL)'
macro call at the end.
A module compiled in this way will be loaded RTLD_NOW|RTLD_LOCAL
so symbol pollution is reduced, and symbols are resolved immediately.
Removing just the '#define STATIC_MODULE' will restore the old
behaviour.
In order for a module to be loaded RTLD_NOW|RTLD_LOCAL, it must not
export any symbol[1], and all the modules it depends on (e.g. res_*)
must be loaded already.
[1] Mechanisms are in place, and will be enabled later, to still
allow such modules to 'export' symbols and resolving the dependencies
irrespective of the load order.

collecting common functions in a single place and removing
them from the individual handlers.
The full description is on mantis,
http://bugs.digium.com/view.php?id=6375
and only the ogg_vorbis handler needs to be converted to
the new structure.
As a result of this change, format_au.c and format_pcm_alaw.c
should go away (in a separate commit) as their functionality
(trivial) has been merged in another file.

in pbx_exec is always 1 so it can be removed.
This change also takes away ast_exec_extension(), and lets all
switch functions (exists, canmatch, exec, matchmore) all use the same
prototype, which makes the code a bit cleaner.

ast_walk_indications(), to walk through the list of indications.
The new method returns an unlocked record, which is no different from the
behaviour of other existing methods in indications.c
(i.e. they all need to be fixed, with refcounts or some similar
method).
Note that ast_walk_indications() uses the pointer argument only as a
search key, so its implementation is completely safe.
In turn, this change allows the removal of AST_MUTEX_DEFINE_EXPORTED.

#define DEFAULT_SAMPLE_RATE 8000

to the main header, and remove equivalent ones from plc.[ch]
This will simplify the cleanup of the codec/ and formats/ files.

which is the basis for several simplifications and fixes
to the CLI interfaces.
The core is in cli.c, some documentation on a new function
to help command completion is in cli.h, and one line of
glue code in the other two files.
Next step is to bring in the patches described in #6066 and
other simplifications.

and updated to today's version.
The core of the patch is only two files, loader.c
and include/asterisk/module.h, with the other files
touched only to adapt non-standard usages of the
reference counts and localuser lists.

writing of common constructs like
chan = !ast_strlen_zero(cdr->channel) ? cdr->channel : "<unknown>";
(or the if/then/else form) into
chan = S_OR(cdr->channel, "<unknown>");
The name can be changed if we find a better (and not too long) one;
currently, it is S as String, OR as it mimics the behaviour of
the || operator, but applied to strings.

can override them.
On passing, fix a potential problem in the top level Makefile:
if a static library is not referenced by any of the core objects,
it is not linked in the main program, and will not be available
to modules, which leads to failure at runtime when the modules
are loaded.
This is the case of stdtime/localtime.o, which supplies some core
symbolx, but is only linked in as a library. Fix the problem by
linking in the object.
NOTE: this is intended as a temporary aid to replace the
existing say.c with a newer implementation. Once the
task is completed, we may decide whether or not the ast_say*()
functions should be pluggable or not and possibly revert
part of this change.

In this specific case the problem triggered on app_amd.c,
but it keeps coming out from time to time so it is better
to fix it in a more central place.
