With --enable-pch=full there's not much difference between a "public"
header in <module>/inc and a private one in <module>/src/somewhere/inc .
And since the script searches recursively, this apparently helps to
find even more headers for lower pch levels.

E.g. #ifdef LIBO_INTERNAL_ONLY is always true for code that builds
with our PCHs.

Ported update_pch.sh to Python with improved performance
and features. The new script is invoked from the same
update_pch.sh which calls it for each library in
parallel, although it can be invoked directly.

The ported script (update_pch) updates all PCH files
in ~15 seconds where the old script took ~4500 seconds.
In addition, the new script supports 3-tiered headers
(system, module, and local) and is very flexible to
support other improvement. It has a per-library
optimal configuration settings that can be updated
using another new scripts (update_pch_autotune.sh)
which finds optimal per-PCH settings.

PCH files have been generated using the new scripts
which builds significantly faster (2-3x, depending
on module and configuration) and the intermediate
binaries are noticably smaller (by several GBs).

The new script stamps each generated PCH file with
the command that generated it to make it trivial
for users to update them, and also adds the command
to invoke another script (update_pch_bisect) that
helps find missing headers or conflicting headers
that may break the build after updating the PCH.

Finally update_pch has built-in unit-tests for
makefile parsing and other core functionality.

This may reduce some degree of dependency on boost.
Done by running a script like:

git grep -l '#include  *.boost/scoped_array.hpp.' \
 | xargs sed -i -e 's@#include  *.boost/scoped_array.hpp.@#include <memory>@'
git grep -l '\(boost::\)\?scoped_array<\([^<>]*\)>' \
 | xargs sed -i -e 's/\(boost::\)\?scoped_array<\([^<>]*\)>/std::unique_ptr<\2[]>/'

... and then killing duplicate or unnecessary includes,
while changing manually
m_xOutlineStylesCandidates in xmloff/source/text/txtimp.cxx,
extensions/source/ole/unoconversionutilities.hxx, and
extensions/source/ole/oleobjw.cxx.
