allow 'show memory' and 'show memory summary' to distinguish memory allocations that were done for caching purposes, so they don't look like memory leaks

/*!
* \brief A wrapper for calloc() for use in cache pools
*
* ast_calloc_cache() is a wrapper for calloc() that will generate an Asterisk log
* message in the case that the allocation fails. When memory debugging is in use,
* the memory allocated by this function will be marked as 'cache' so it can be
* distinguished from normal memory allocations.
*
* The arguments and return value are the same as calloc()
