From 4d2537ae1136e6885c3b1214ebed6ccab2bdbec2 Mon Sep 17 00:00:00 2001
From: "Kevin P. Fleming" <kpfleming@digium.com>
Date: Thu, 5 May 2005 05:39:33 +0000
Subject: major re-work of dialplan functions, including:

 - locking of functions list during registration/unregistration/searching
 - rename of function description structure to be consistent with the rest of the API
 - addition of 'desc' element to description structure, for detailed description (like applications)
 - addition of 'show function' CLI command to show function details
 - conversion of existing functions to use uppercase names to match policy
 - creation of new 'pbx_functions.so' module to contain standard 'builtin' functions
 - removal of all builtin functions from pbx.c and apps and placement into new 'funcs' directory
