jit: avoid integer wraparound in stack size definition ( #42 )
...
pcre2_jit_stack_create() allows the user to indicate how big of a
stack size JIT should be able to allocate and use, using a size_t
variable which should be able to hold bigger values than reasonable.
Internally, the value is rounded to the next 8K, but if the value
is unreasonable large, would overflow and could result in a smaller
than expected stack or a maximun size that is smaller than the
minimum..
Avoid the overflow by checking the value and failing early, and
while at it make the check clearer while documenting the failure
mode.
