Conditional NP2 textures in Direct3D do not support D3DTADDRESS_WRAP
texture addressing. Similarly, GL_ARB_texture_rectangle textures do
not support GL_REPEAT. This patch adds a test which shows that _WRAP
clamps to the texture edge and implements that.

We have to destroy potential fbo renderbuffers, and make sure the
texture is gone

Include d3dx8mesh.h in d3dx8.h and add some commented out ones as reminders.

We still fallback to an idle server, but this prevents a client from
connecting to a named pipe server that isn't listening.

ntdll: The FileMailslotSetInformation and FileCompletionInformation cases of NtSetInformationFile don't need the fd.

So don't do an extra server call to get the fd to avoid a performance
penalty and to make these cases work when an fd isn't available.
