Summary:                    [patch] Functions INC and DEC
Description: 
Over the course of time, developing Asterisk dialplans becomes fairly
cumbersome, especially when writing While() loops in the dialplan. Mainly,
when we want to iterate a few times, the ever annoying Set(Var=$[${Var} +
1]) is really annoying.
INCrement and DECrement follow the old PASCAL functions, allowing to
increment and decrement a variable.

The functions are built to handle both numeric and alpha-numeric values.
If an alpha-numeric value is given, the functions will simply bail out and
issue a LOG_NOTICE accordingly.

In order to implement this, i've added some functionality to func_math.c
and added a new ast_is_numeric function to strings.h

Please find attached patches for TRUNK.

Hi Guys,

  New patch uploaded with fixes. I've decided to remove the strdupa and
remain with the locks. As I'm dealing with variables, I would like to
maintain the lock by myself and verify it's there till I finish the thing.

  I've also added another check into the mix, to verify that the functions
always unlocks, even in the case of an error.
