match: avoid crash if subject NULL and PCRE2_ZERO_TERMINATED (#53)
* pcre2_match: avoid crash if subject NULL and PCRE2_ZERO_TERMINATED

When length of subject is PCRE2_ZERO_TERMINATED strlen is used
to calculate its size, which will trigger a crash if subject is
also NULL.

Move the NULL check before strlen on it would be used, and make
sure or dependent variables are set after the NULL validation
as well.

While at it, fix a typo in a debug flag in the same file, which
is otherwise unrelated and make sure the full section of constrain
checks can be identified clearly using the leading comment alone.

* pcre2_dfa_match: avoid crash if subject NULL and PCRE2_ZERO_TERMINATED

When length of subject is PCRE2_ZERO_TERMINATED strlen is used
to calculate its size, which will trigger a crash if subject is
also NULL.

Move the NULL check before the detection for subject sizes to
avoid this issue.

* pcre2_substitute: avoid crash if subject or replacement are NULL

The underlying pcre2_match() function will validate the subject if
needed, but will crash when length is PCRE2_ZERO_TERMINATED or if
subject == NULL and pcre2_match() is not being called because
match_data was provided.

The replacement parameter is missing NULL checks, and so currently
allows for an equivalent response to "" if rlength == 0.

Restrict all other cases to avoid strlen(NULL) crashes in the same
way that is done for subject, but also make sure to reject invalid
length values as early as possible.

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.

improve on 'auto' mode for DISABLE_PERCENT_ZT (#28)
Visual Studio 2013 includes support for %zu and %td, so let newer
versions of it avoid the fallback, and while at it, make sure that
the first check is for DISABLE_PERCENT_ZT so it will be always
honoured if chosen.

prtdiff_t is signed, so use a signed type instead, and make sure
that an appropiate width is chosen if pointers are 64bit wide.

Remove the need for the size_t cast and instead change the size
of the equivalent format identifier to avoid truncations.
