drm/vmwgfx: Fix compat shader namespace
Contrary to the host-backed shader interface that has a per-context
name-space for shaders, the compat shader namespace was per client
(or rather, per file). Fix this so that the compat shader namespace is per
context, and at the same time, make command buffer managed context resource
management generic.

drm/vmwgfx: Fix query buffer locking order violation
The query buffers were reserved while holding the binding mutex, which
caused a circular locking dependency.

drm/vmwgfx: Use a per-device semaphore for reservation protection
Don't use a per-master semaphore (ttm lock) for reservation protection, but
rather a per-device semaphore. This is needed since clients connecting using
render nodes aren't master aware.
The ttm lock used should probably be replaced with a reader-write semaphore
once the function down_xx_interruptible() is available.

drm/vmwgfx: Reemit context bindings when necessary v2
When a context is first referenced in the command stream, make sure that all
scrubbed (as a result of eviction) bindings are re-emitted. Also make sure that
all bound resources are put on the resource validate list.
This is needed for legacy emulation, since legacy user-space drivers will
typically not re-emit shader bindings. It also removes the requirement for
user-space drivers to re-emit render-target- and texture bindings.
Makes suspend and hibernate now also work with legacy user-space drivers on
guest-backed devices.
v2: Don't rebind on legacy devices.
