Reviewed-by: Eric Anholt <eric@anholt.net>

v3d: use the GPU to record primitives written to transform feedback

We can use the PRIMITIVE_COUNTS_FEEDBACK packet to write various primitive
counts to a buffer, including the number of primives written to transform
feedback buffers, which will handle buffer overflow correctly.

There are a couple of caveats with this:

Primitive counters are reset when we emit a 'Tile Binning Mode Configuration'
packet, which can happen in the middle of a primitives query, so we need to
read the buffer when we submit a job and accumulate the counts in the context
so we don't lose them.

We also need to do the same when we switch primitive type during transform
feedback so we can compute the correct number of recorded vertices from
the number of primitives. This is necessary so we can provide an accurate
vertex count for draw from transform feedback.

v2:
 - When computing the number of vertices for a primitive, pass in the base
   primitive, since that is what the hardware will count.
 - No need to update primitive counts when switching primitive types if
   the base primitives are the same.
 - Log perf warning when mapping the primitive counts BO for readback (Eric).
 - Only emit the primitive counts packet once at job end (Eric).
 - Use u_upload mechanism for the primitive counts buffer (Eric).
 - Use the XML to generate indices into the primitive counters buffer (Eric).

panfrost: Allocate shaders in their own BOs

Instead of all shaders being stored in a single BO, have each shader in
its own.

This removes the need for a 16MB allocation per context, and allows us
to place transient blend shaders in BOs marked as executable (before
they were allocated in the transient pool, which shouldn't be
executable).

v2: - Store compiled blend shaders in a malloc'ed buffer, to avoid
      reading from GPU-accessible memory when patching (Alyssa).
    - Free struct panfrost_blend_shader (Alyssa).
    - Give the job a reference to regular shaders when emitting
      (Alyssa).

v3: - Split out the allocation flags change (Rob).

util/hash_table: Fix hashing in clears on 32-bit

Some hash functions (eg. key_u64_hash) will attempt to dereference the
key, causing an invalid access when passed DELETED_KEY_VALUE (0x1) or
FREED_KEY_VALUE (0x0).

When in 32-bit arch a 64-bit key value doesn't fit into a pointer, so
hash_table_u64 internally use a pointer to a struct containing the
64-bit key value.

Fix _mesa_hash_table_u64_clear() to handle the 32-bit case by creating a
temporary hash_key_u64 to pass to the hash function.

anv: support GetSwapchainGrallocUsage2ANDROID for Android

New function supports gralloc1 usage flags that get set separately
for producer and consumer. As we still need to support old method too,
let's share common code and use android_convertGralloc0To1Usage helper.
Bump the VK_ANDROID_native_buffer version to indicate support for the
new call.

Changes were tested on Android Celadon P with Basemark GPU and various
Sascha Willems Vulkan demos.
