Update to PCRE 8.33, w/o the erts_ prefix added
Add erts_prefix to pcre_library and update erl_bif_re
Handle CRLF correctly in global regexp
Integrate patch for PCRE bug id 1370
Integrate new PCRE test suites

The relevant testoutputNN files were copied from the
PCRE distribution and some corrections were done to
run_pcre_tests.erl.

Also made test generator be more compiler friendly

The re_testoutput1_replacement_test and
re_testoutput1_split_test modules that are
generated by run_pcre_tests.erl (offline,
when a new version of PCRE is integrated in the VM)
took forever to compile, as one single huge function
contained all the tests. The autogenerated tests are now
split into ~50 functions, which reduces compile time to
approximately a third.

New automatic test suites are also generated from the
new testoutputNN files, and checked in.
Update PCRE doc part of re.xml to PCRE 8.33 state

This does not include any documentation of the new options,
namely 'ucp', 'never_utf', 'notempty_atstart', 'no_start_optimize' or
{capture, all_names, ...} and re:inspect/1.
Add new options to Erlang re interface and mend dupnames

Add notempty_atstart, no_start_optimize, ucp and
never_utf options from new PCRE version.

Use the new notempty_atstart in global matching.

Add inspect/2 function

Correctly handle dupnames when capturing a name, as
in Perl, get the leftmost matching occurence.
Also added all_names, to get all the names in the pattern
in alphabetical (name) order.
To be able to use this in global matching, an inspect
function that can dig out a namelist was added.
Add documentation of extensions to re module

The following compile options are documented:
no_start_optimize
ucp
never_utf
The following run options are documented:
notempty_atstart
{capture, all_names}
The following new functions are documented:
re:inspect/2
Add README for updating PCRE
Add return_errors option to re:run/3
Add match_limit and match_limit_recursion options

Added to re:run and sets the corresponding fields in 'extra' struct
for the PCRE match engine. The result can be viewed by also
setting 'report_errors' when matching.

Some housekeeping was also done...

The offset option also did not properly check for offset's >= 0.

Change nomatch to BADARG when pre-compiled mp() is faked:
By constructing a 5-tuple with faked content but the right data types,
you could do a re:run which returned nomatch when in fact the mp() was
bad. The cheapest solution is to check the return from pcre_exec
better.

Remove unreachable code in erts_bif_re.c:
Replaced tests for things that logically simply
cannot happen with ASSERT.
Add documentation of report_errors and match_limit(_recursion)
Add more tests for corner error cases in erl_bif_re.c
Correct UTF-8 in stdlib's notes.xml
Fix backslash in titles of manpages

A cludge which replaces one backslash with three in section headers when
generating manpages from xml files.
Clarify relation between erts_iolist_{size|to_buf}

Just some clarifying comments to future progremmers to keep the relation
between error returns from the two functions.
Workaround TR gnu/181328, GCC 4.2.1 20070831 on FreeBSD 9.1

The bug manifests so that initialization of an automatic variable
happens after a pointer to the variable is dereferenced, causing
build_exec_return to take the wrong branch by default.

The bug is verified to happen even outside the VM and
is reported to FreeBSD as trouble ID gnu/181328.

The workaround is a slight code rewrite which is optimized differently.

Also removed two warnings about dereferencing type-punned
pointers, which did not affect the bug.
