Asterisk applications register themselves with ast_application_register.
They should have a short, unique name, and an exec function which takes
as its arguments a channel and some data that might be useful for callback
stuff. Remember to keep track of how many and which channels are using
your application so that should the module need to be unloaded
(particularly force unloaded), you will be able to ast_softhangup all the
channels. An application should *never* call ast_hangup on the channel
that it is running on (although it could conceivably hang up other
channels that it allocates). See app_playback.c as an example of a simple
application.

All modules must have at least the following functions:
int load_module():
Do what you need to do when you get started. This function
returns 0 on sucess and non-zero on failure (it is not considered loaded
if it failes.
int unload_module():
The module will soon be unloaded. If any channels are using your
features, you should give them a softhangup in an effort to keep the
program from crashing. Generally, unload_module is only called when the
usecount is 0 or less, but the user can force unloading at their
discression, and thus a module should do its best to comply (although in
some cases there may be no way to avoid a crash). This function should
return 0 on success and non-zero on failure (i.e. it cannot yet be
unloaded).
char *description():
Return a description of the module's functionality.
int usecnt():
Return the number of channels, etc that are using you.
