rpcrt4: Flesh out more of the IRpcChannelBuffer vtable to make the test_delegating_Invoke test succeed on Windows.

uninstaller: Iterate keys in HKEY_CURRENT_USER also as some programs install their uninstall information there.

winhelp: Correctly deal with various TopicBlockSize/Compression combinations. Simplify HLPFILE_Uncompress_Topic function.

I'm resending this patch because my reply to Henri's concern came too late. 
Henri noted that I am enabling lights that do not exist. Existing tests show 
that if no light is assigned to the index, LightEnable creates a light with a 
set of default parameters, so the tests should be fine.

Subject: [PATCH] WineD3D: Enabling too many lights is silently ignored

This patch adds tests for all d3d versions that show that Windows
pretends that enabling more lights than supported succeeds. D3D_OK is
returned, and the light is reported as enabled.

What is not tested in this patch is the rendering output of this
situation, thus the FIXME is still written.

wined3d: Fix handling of a special case in IWineD3DImpl_FillGLCaps() and adjust type of loop variable.

d3dx8: Initialise temp in D3DXQuaternionInverse to avoid a uninitialised variable warning with some versions of gcc.

In one condition (fMustAlloc == TRUE), base_ptr_val may be uninitialised
and so cause a valgrind warning. Reversing the check is harmless and
doesn't result in a performance decrease.
