- 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
