New Revision: 407104

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=407104
Log:
app_stack: protect against missing parameters to STACK_PEEK and LOCAL_PEEK

STACK_PEEK requires 2 parameters and LOCAL_PEEK requires 1 parameter.  This
protects against situations where those parameters are blank or missing by
logging an error and returning.

(closes issue ASTERISK-23220)
