Growing the reloc list happens through calling anv_reloc_list_add() or
anv_reloc_list_append(). Make sure that we call these through helpers
that check the result and set the batch error status if needed.
v2:
- Handling the crashes is not good enough, we need to keep track of
the error, for that, keep track of the errors in the batch instead (Jason).
- Make reloc list growth go through helpers so we can have a central
place where we can do error tracking (Jason).
v3:
- Callers that need the offset returned by anv_reloc_list_add() can
compute it themselves since it is extracted from the inputs to the
function, so change the function to return a VkResult, make
anv_batch_emit_reloc() also return a VkResult and let their callers
do the error management (Topi)
v4:
- Let anv_batch_emit_reloc() return an uint64_t as it originally did,
there is no real benefit in having it return a VkResult.
- Do not add an is_aux parameter to add_surface_state_reloc(), instead
do error checking for aux in add_image_view_relocs() separately.

Most of the time we use macros that handle this situation transparently,
but there are some cases were we need to handle this explicitly.
This patch makes sure we don't crash, notice that error handling takes
place in the function that actually failed the allocation,
anv_batch_emit_dwords(), which will set the status field of the batch
so it can be used at a later moment to report the error to the user.
v2:
- Not crashing is not good enough, we need to keep track of the error
(Topi, Jason). Iago: now that we track errors in the batch, this
is being handled.
- Added guards in a few more places that needed it (Iago)
v3:
- Check result of anv_batch_emitn() for NULL before calling memset()
in emit_vertex_input() (Topi)

The anv_batch_set_error() helper will track the first error that happened
while recording a command buffer. The helper returns the currently tracked
error to help the job of internal functions that may generate errors that
need to be tracked and return a VkResult to the caller.
We will use the anv_batch_has_error() helper to guard parts of the driver
that are not safe to execute if an error has been generated while recording
a particular command buffer.

The vkCmd*() functions do not report errors, instead, any errors should be
reported by the time we call vkEndCommandBuffer(). This means that we
need to make the driver robust against incosistent and/or imcomplete
command buffer states through the command recording process, particularly,
avoid crashes due to access to memory that we failed to allocate previously.
The strategy used to do this is to track the first error ocurred while
recording a command buffer in the batch associated with it. We use the
batch to track this information because the command buffer may not be
visible to all parts of the driver that can produce errors we need to be
aware of (such as allocation failures during batch emissions).
Later patches will use this error information to guard parts of the driver
that may not be safe to execute.
v2: Move the field from the command buffer to the batch so we can track
errors from batch emissions (Jason)
v3: Registering errors in the command buffer's batch during
anv_create_cmd_buffer() is unnecessary, since the command buffer
is freed at the end of the function in that case (Topi)

This situation can happen if we failed to allocate memory for the shader.
v2:
- We shouldn't see NULL shaders in anv_shader_bin_ref so we should not check
for that (Jason). Make sure that callers don't attempt to call this
function with a NULL shader and assert that this never happens (Iago).
v3:
- All callers to anv_shader_bin_unref seem to check for NULL before calling,
so just assert that it is not NULL (Topi)

While a context only has a single glthread, the context itself can be
attached to several threads. Therefore the dispatch table must be

The threading for GL core is in place, but there are so few applications
actually using a core GL context that it would be nice to extend support
back. However, some of the features of compat GL (particularly user
vertex arrays) would be so expensive to track state for that we want to be
able to disable threading when we discover that the app is using them.

This patch splits the context's CurrentDispatch pointer into two
pointers, CurrentClientDispatch, and CurrentServerDispatch, so that
when doing multithread marshalling, we can distinguish between the
dispatch table that's being used by the client (to serialize GL calls
into the marshal buffer) and the dispatch table that's being used by
the server (to execute the GL calls).

Without doing some additional tracking, we won't know whether the data
will be immediate user data, or will be loaded from a PBO. The normal
teximage functions will be sync by default because they don't know up
front what the size of their image data is. But for compressed teximage,
we have the count information, so they would end up async by default.

Several API functions require special treatment in order to be marshalled
to a background thread. Others can't be safely executed in a background
thread and need to be executed synchronously (e.g. since they return data
through a pointer argument).
This annotation will be used when code generating thread marshalling code,
to ensure that each function is marshalled in the correct way.
Note that PixelMap functions are marked as synchronous for now since
their pointer may be relative to buffer on the GPU, so we'll need
special logic to marshal them properly.
