  Don't overflow when paging more than 128 extensions
  
  The number of available slots for calls in app_page was hardcoded to 128.
  Proper bounds checking was not in place to enforce this limit, so if more than
  128 extensions were passed to the Page() app, Asterisk would crash.  This patch
  instead dynamically allocates memory for the ast_dial structures and removes
  the (non-functional) arbitrary limit.
  
  This issue would have special importance to anyone who is dynamically creating
  the argument passed to the Page application and allowing more than 128
  extensions to be added by an outside user via some external interface.
  
  The patch posted by a_villacis was slightly modified for some coding guidelines
  and other cleanups.  Thanks, a_villacis!
