ole32: Move the logic in StgCreateDocfile for "if no share mode given then DENY_NONE is the default" to before the validateSTGM check.

Add a test that shows this behaviour is correct.

Remove a test on the access mode that is redundant because it is already 
done in validateSTGM.

Add test for a new error condition and tests for returning data from values of different registry value types.

DDSCL_NORMAL is not set at initialization. Instead of making this a
& DDSCL_NORMAL || == 0 check just set fullscreen mode always. WineD3D
will catch NOP changes anyway.

Cards at DirectX7 times did not support non power of 2 textures, and
some games check the capatiblity flags incorrectly. Rollcage expects the
D3DPTEXTURECAPS_POW2 (limitation) flag set and fails with the reference
rasterizer which support NP2 textures and doesn't have the cap set.

kernel32: Set the new definition for an activation context, and implement adding/releasing references to it.

Remove vbos from the input strided data from the fixed function
attributes explicitly and avoid writing beyond the end of a temporary
buffer when cloning a windows bug.

Spotted by Coverity.

Fixes the erros when using anisotropic mag filtering in the d3d7
filter demo.
