See <https://bugs.kde.org/show_bug.cgi?id=284384> "clang 3.1 -Wunused-value
warnings in valgrind.h, memcheck.h" for a way to silence these warnings when
building with clang.

starting with LO 3.4 we default to using libxslt for xslt transformations
in filters. the saxon/j based services is still available and can be
explicitly requested by filters using the 2nd userdata entry in the filter
configuration. There wasn't any place to edit this 2nd userdata entry,
and it wasn't exported or imported with the custom filter packages.

Supports importing the 2nd userdata parameter for xslt filter
definitions from manually edited custom XML filter settings.

UI currently not available.

And let $(prog), $(progpath), $(progurl) point to brand program/
instead of basis program/.

Remove the mutex member of ViewObjectContactOfUnoControl_Impl and use
the SolarMutex instead, because the current usage of 2 mutexes is just
too prone to deadlock.

The dependecy from the outdir lib to the component file is racy, because
we preserve timestamps when delivering: if the component file and the
workdir library are built in parallel, and the component file ends up
being newer, then the library will always be delivered because its
timestamp is always older.  Work around this by having the workdir
library depend on the component file.

Must use gb_Library_add_noexception_objects instead of
gb_Library_add_cxxobjects so that -DEXCEPTIONS_OFF is passed to the
compilation. (In this case, it affects code in
com/sun/star/uno/genfunc.hxx.)

warning C4928: illegal copy-initialization; more than one user-defined
conversion has been implicitly applied. So use a variable of the
correct type, should not affect the intent of the code.

The ScVbaFormatConditions class is used only as a target for casting,
it seems, and no objects of this type are created as such, I think.
So avoid MSVC warnings:

warning C4510: 'ScVbaFormatConditions' : default constructor could not
be generated

warning C4610: class 'ScVbaFormatConditions' can never be instantiated
- user defined constructor required

+ use the version 3.5 instead of 3.4
+ use /opt/lo-dev instead of /opt/libreoffice3.4
+ new options:
    + -d/--download just download the last build
    + -s/--headless use the headless mode when running the smoke test
    + -l/--loop do download/install/smoketest in a loop; do it jsut once
      by default
+ uninstall the old version when -i/--install option is used
+ mention PASSED/FAILED in the test log
+ restore compat symlinks to prebuilt binaries when they do not exits
+ complain when build.cfg is missing

The reference counting of ScDocShell is very confused. It starts off with ref
count of 1, assigning it to a ScDocShellRef gives it a refcount of 2, so
clearing it or its dtor gives a refcount of 1 again, so it doesn't auto-delete,
and so doesn't close its stream, so the attempt to remove its stream gives
E_ACCESS under windows.

Also removed apparently unused UNO_JAVA_COMPPATH ProfileItem.

This allows xmlsecurity to be built even when --disable-mozilla is provided.
