For some documents it was observed that the PDF-export switches the font after
text layout and before text drawing/measuring. This use case is quite atrocious
and unexpected and crashed our CoreText glue code. The other platforms survive
it though; to minimize the risk to them only the CoreText glue gets adapted to
survive this scenario.

putenv() has changed its semantic to no longer copy input buffers which
results in problems if the input buffers were only temporary. Using
setenv(), which still copies the input buffers solves the problem.

Fixed access bridge initialization issue in vcl.

i124573: Initialize flags to allow acess bridge initialization to fail gracefully (Merged from branch AOO410).

124553: <SwAcccessibleCell::SwAccessibleCell(..)> - correct initialization of new members introduced for IA2

#124467# merge from aoo410 branch, add check for image data offset against stream length, some further checks

#124453# merge from aoo410 branch, check if the resulting polygon has already exceeded the number of points (2^16) that can be handled by a tools polygon

When running into invalid Unicode surrogate pairs the text layout code on
Windows ran into massive problems like crashes. This change detects the
situation of an invalid surrogate pair and falls back to treat it as
a simple character instead of requesting a complex glyph fallback.

When exceptions are passed around in uno::Any types to be thrown later it
was observed on OSX64 that the type_info symbols of these exceptions were
not available anywhere. On most platforms the UNO bridge would synthesize
them by emulating how the platform's toolchain would do it. Forcing the
emission of the type_infos by the real toolchain is much better than
second guessing and reverse engineering its operation.

An even better approach would be to have the ucb throw the exceptions itself
instead of wrapping, rewrapping, unwrapping, etc. them. Once this is done
the dummyThrower helper function is no longer needed.
