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/.

The PCRE APIs
-------------
PCRE is written in C, and it has its own API. There are three sets of functions,
one for the 8-bit library, which processes strings of bytes, one for the
16-bit library, which processes strings of 16-bit values, and one for the 32-bit
library, which processes strings of 32-bit values. The distribution also

32-bit library, which processes strings of 32-bit values. The distribution also
includes a set of C++ wrapper functions (see the pcrecpp man page for details),

The following error may occur when compiling with native compilers in the Tru64
operating system:

#error "cannot include iosfwd -- define __USE_STD_IOSTREAM to override default

This may be followed by other errors, complaining that 'namespace "std" has no
member'. The solution to this is to add the line
#define __USE_STD_IOSTREAM 1

The RunTest script runs the pcretest test program (which is documented in its
own man page) on each of the relevant testinput files in the testdata
directory, and compares the output with the contents of the corresponding

were selected. For example, the tests for UTF-8/16/32 support are run only if
--enable-utf was used. RunTest outputs a comment when it skips a test.

from pcretest. Other files whose names begin with "test" are used as working
files in some tests.
Some tests are relevant only when certain build-time options were selected. For
example, the tests for UTF-8/16/32 support are run only if --enable-utf was
used. RunTest outputs a comment when it skips a test.
Many of the tests that are not skipped are run up to three times. The second
run forces pcre_study() to be called for all patterns except for a few in some
tests that are marked "never study" (see the pcretest program for how this is
done). If JIT support is available, the non-DFA tests are run a third time,
this time with a forced pcre_study() with the PCRE_STUDY_JIT_COMPILE option.
This testing can be suppressed by putting "nojit" on the RunTest command line.
The entire set of tests is run once for each of the 8-bit, 16-bit and 32-bit
libraries that are enabled. If you want to run just one set of tests, call
RunTest with either the -8, -16 or -32 option.
RunTest uses a file called testtry to hold the main output from pcretest.
Other files whose names begin with "test" are used as working files in some
tests. To run pcretest on just one or more specific test files, give their
numbers as arguments to RunTest, for example:
If valgrind is installed, you can run the tests under it by putting "valgrind"
on the RunTest command line. To run pcretest on just one or more specific test
files, give their numbers as arguments to RunTest, for example:
RunTest 2 7 11
You can also specify ranges of tests such as 3-6 or 3- (meaning 3 to the
end), or a number preceded by ~ to exclude a test. For example:
Runtest 3-15 ~10
This runs tests 3 to 15, excluding test 10, and just ~13 runs all the tests
except test 13. Whatever order the arguments are in, the tests are always run
in numerical order.
You can also call RunTest with the single argument "list" to cause it to output
a list of tests.
