Can I ask for a small document, in either docs/ or funcs/, which
describes how such a function has to be added (well, just add it
to the Makefile), how to define a function internally (define it
as a "struct ast_custom_function"), what are the required fields
in the ast_custom_function are and (md5_function doesn't have the .desc for
example, while cdr_function has .write), which mutexes to lock when
playing around with the chan variable, when to load configuration
files (for apps this was done in load_module()) etc etc etc.

This is purely from a point of somebody who has been asked to convert
his implementation of apps/app_enumlookup.c to funcs/func_enum.c.
