Summary:                    [patch] Add a new function to check if a
extension[,priority] exits in a context
Description: 
this is a wrapper to ast_exists_extension and/or ast_findlabel_extension

this will be used to avoid goto falling off the map/hanging up ... if
there is no extension 

ie

exten =>t,n,
GotoIf(${ISEXTEN(ivr-${IVRCONT},${NEWUEXTEN})}?ivr-${IVRCONT},${NEWUEXTEN},1)

will work or continue on to next priority or alternate

id like to propose
 
ast_exists_context function in pbx.c unless there alternatives doing this
will allow access to the cache and ast_context that are exposed.

im not arround much at the moment silly season and all will do this
tommorow unless there objections.

i vote for DP_EXISTS shorter and the letters are worn off my keyboard
already ;)

another use of this function is to circumvent users pressing duplicates in
the IVR thinking there first press did not go through. check and if there
proceed with double otherwise if exits proceed with single press ....

thx for the intrest
