Regex: Update PCRE to v8.35.

Browse Source 
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/.

This document describes the optional features of PCRE that can be selected when
the library is compiled. It assumes use of the <b>configure</b> script, where
the optional features are selected or deselected by providing options to
<b>configure</b> before running the <b>make</b> command. However, the same
options can be selected in both Unix-like and non-Unix-like environments using
the GUI facility of <b>cmake-gui</b> if you are using <b>CMake</b> instead of
<b>configure</b> to build PCRE.
PCRE is distributed with a <b>configure</b> script that can be used to build the
library in Unix-like environments using the applications known as Autotools.
Also in the distribution are files to support building using <b>CMake</b>
instead of <b>configure</b>. The text file
<a href="README.txt"><b>README</b></a>
contains general information about building with Autotools (some of which is
repeated below), and also has some comments about building on various operating
systems. There is a lot more information about building PCRE without using
Autotools (including information about using <b>CMake</b> and building "by
hand") in the text file called
<a href="NON-AUTOTOOLS-BUILD.txt"><b>NON-AUTOTOOLS-BUILD</b>.</a>
You should consult this file as well as the

file if you are building in a non-Unix-like environment.
