There is no valid reason for the guest to pass bad resource ids.
Because resource creation failures are not propagated back to the guest,
they are the most common reason for the guest to pass bad resource ids.
When that happens, failing earlier makes things easier to debug.

A vrend_context structure contains a current vrend_sub_context, which
in turn keeps references on various resources like textures, VBOs,
index buffers, etc. which are used for actual drawing operations.
Certain actions can change the current sub-context in use.
There is a split of what resources are cleaned up directly as part of
a context destruction and which are handled by the sub-context
destruction. VBOs, while referenced by sub-contexts, are cleaned up by
the context. To do that, it uses the at the time of destruction
current sub-context to access these. As a result, only the VBOs in the
active sub-context are cleaned up; every other sub-context referenced
by the context will keep references to the VBOs used.
The responsibility of VBO dereferencing is moved to the destruction of
the sub-context, so all VBOs, not just the one from the current
sub-context, are dereferenced during the destruction of a context.
Closes#198

This was regressed by commit 3a2a537c (vrend: hook up per-context
fencing internally), bisected by Gert.
When there is no sync thread, vrend_renderer_check_fences checks fences
on vrend_state.fence_list for signaled ones and call ctx->fence_retire
on them. Because fences belonging to the same context are ordered, as
an optimization, we ideally want to call ctx->fence_retire only on the
last fence of those belonging to the same context. (Note we are close to
that but not quite because we want to avoid complex changes until virgl
starts using per-context fencing, if ever)
The issue is in need_fence_retire_signal_locked. It has this check
if (fence->fences.next == &vrend_state.fence_list)
return true;
which says that, if the fence is the last one in vrend_state.fence_list,
call ctx->fence_retire (because it must be the last fence of some
context). The check is incorrect because not all fences on the list
have signaled when the sync thread is not used. It will fail when there
are also unsignaled fences on the list.
To fix the issue, we contruct a list of signaled fences first before
calling need_fence_retire_signal_locked. We could merge the paths with
and without sync thread further because the non-sync-thread path just
needs this extra step to construct a list of signaled fences. But we
will save that for future and focus on fixing the performance
regression.

Avoids compiling shader variants in the host driver if they will never
be used for rendering.
Wait to register shaders with the host GL driver until after shader
dependencies have been resolved and the selected set of variants is
known to be used for rendering.
The cost of this workaround is taht TGSI to GLSL conversion is still
performed for every variant (observed to happen twice for every
vertex/fragment shader in some cases), but this is expected to be much
cheaper than calling out to the host driver to compile unused variants.
Workaround for #180.

Shader programs are submitted for linking in the host driver twice as
frequently as for native applications due to circular shader
dependencies, immediate TGSI conversion, and explicit shader variant
selection ordering at draw-time.
Circular dependencies are resolved by re-running shader variant
selection twice before emitting calling glUseProgram() in the host.
The cost of this workaround is that GLSL is still emitted to the host
driver for compilation into intermediate/native instructions even for
unused shader variants, but the extraneous linking has been eliminated.
Workaround for #180.
