Thanks to Bamm Gabriana for the info.

rpcrt4: Use an alertable wait in rpcrt4_protseq_np_wait_for_new_connection to fix a small memory leak flagged by Valgrind.

This is called only by the RPCRT4_server_thread so we don't have to 
worry about application user APCs being run at improper times.

Destroy the windows that have been created when they are no longer needed.

oleaut32: Set the number of locks held on the safe arrays in the safe array tests to zero before destroying them, otherwise the operation will fail and leak memory.

oleaut32: Don't call SafeArrayAllocData in LPSAFEARRAY_UserUnmarshal if we called SafeArrayCreateEx instead of SafeArrayAllocDescriptor.

Otherwise, we'll leak memory.

The GL_ARB_vertex_program extension does not define a standard value for
output texture coordinates. This makes problems when using vertex
shaders with fixed function fragment processing because fffp divides the
texture coords by its .w component. This means that gl shaders have to
write to the .w component of texture coords. Direct3D shaders however
do not.

ddraw: Rename DDRAW_dump_flags_() to DDRAW_dump_flags_nolf() to clarify its difference from DDRAW_dump_flags().
