Arkshine d4de0e6f1e Regex: Update PCRE to v8.35. 
I was über lazy at first, so took libs from SM.
But actually it's quite easy to compile, so let's update to latest version \o/.

* PCRE testing program *
*************************************************/
/* This program was hacked up as a tester for PCRE. I really should have
written it more tidily in the first place. Will I ever learn? It has grown and
been extended and consequently is now rather, er, *very* untidy in places. The
addition of 16-bit support has made it even worse. :-(

/* This program now supports the testing of all of the 8-bit, 16-bit, and
32-bit PCRE libraries in a single program. This is different from the modules
such as pcre_compile.c in the library itself, which are compiled separately for
each mode. If two modes are enabled, for example, pcre_compile.c is compiled
twice. By contrast, pcretest.c is compiled only once. Therefore, it must not
make use of any of the macros from pcre_internal.h that depend on
COMPILE_PCRE8, COMPILE_PCRE16, or COMPILE_PCRE32. It does, however, make use of
SUPPORT_PCRE8, SUPPORT_PCRE16, and SUPPORT_PCRE32 to ensure that it calls only
supported library functions. */

using a single macro to do this in a generic way, because of the many different
argument requirements. We know that at least one of SUPPORT_PCRE8 and
SUPPORT_PCRE16 must be set. First define macros for each individual mode; then
use these in the definitions of generic macros.
**** Special note about the PCHARSxxx macros: the address of the string to be
printed is always given as two arguments: a base address followed by an offset.
The base address is cast to the correct data size for 8 or 16 bit data; the
offset is in units of this size. If the string were given as base+offset in one
argument, the casting might be incorrectly applied. */

terminated by CRLF, an advance of one character just passes the \r,
whereas we should prefer the longer newline sequence, as does the code in
pcre_exec(). Fudge the offset value to achieve this. We check for a
newline setting in the pattern; if none was set, use PCRE_CONFIG() to
