This function provides control over the memory used by JIT as a run-time stack
when <b>pcre2_match()</b> or <b>pcre2_jit_match()</b> is called with a pattern
that has been successfully processed by the JIT compiler. The information that
determines which stack is used is put into a match context that is subsequently
passed to a matching function. The arguments of this function are:

mcontext a pointer to a match context
callback a callback function
callback_data a JIT stack or a value to be passed to the callback
