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.

It seems that You're using some bad editor, as there are some spacing
changes.

You can do diff -w to ignore whitespace changes :)

Also, i would suggest not using MyVar in doc, but something in lowercase -
like <variable>, and the same name in syntax warning (of which i'm still
not sure that it should be warning :)

Btw, looking at the code of ast_is_numeric - does this work with negative
numbers? Are numbers >2^31 allowed in dialplan variables? If not, i would
go with simpler checking.
