nvc0: take extra pushbuf space into account for pushbuf_space calls

See detailed explanation of why this is needed in commit eb60a89bc3a.
This spot was missed/overlooked. Basically as a result of the fact
that BEGIN_* ends up calling PUSH_SPACE, which in turn adds an extra 8
to the requested amount, we have to be mindful of that when doing bare
nouveau_pushbuf_space calls.

Reportedly this fixes some crashes when replaying a hitman trace taken
on radeonsi.

gallium/targets: don't leave an empty target directory(ies)

Some drivers do not support certain targets - for example nouveau
doesn't do VAAPI, while freedreno doesn't do of the video backends.

As such if we enter vdpau when building freedreno/ilo/etc, a vdpau/
folder will be created, empty library will be build and almost
immediately removed. Thus keeping an empty vdpau/ folder around.

There are two ways to fix this.

 * add substantial tracking in configure/makefiles so that we never end
up in targets/vdpau
 Downsides:
Error prone, as the configure checks and the 'include
gallium/drivers/foo/Automake.inc' can easily get out of sync.

 * remove the folder, if empty, alongside the empty library.
 Downsides:
In the latter case vdpau/ might be empty before the mesa build has
started, yet we'll remove it either way.

This patch implements the latter option, as the downside isn't that
significant, plus the patch is way shorter ;-)

v2: use has_drivers to track since TARGET_DRIVERS can contain space,
hence neither string comparison nor -n/-z works correctly.

util/disk_cache: compress individual cache entries

This reduces the cache size for Deus Ex from ~160M to ~30M for
radeonsi (these numbers differ from Grigori's results below
probably due to different graphics quality settings).

I'm also seeing the following improvements in minimum fps in the
Shadow of Mordor benchmark on an i5-6400 CPU@2.70GHz, with a HDD:

no-cache:                    ~10fps
with-cache-no-compression:   ~15fps
with-cache-and-compression:  ~20fps

Note: The with cache results are from the second run after closing
and opening the game to avoid the in-memory cache.

Since we mainly care about decompression I went with
Z_BEST_COMPRESSION as suggested on irc by Steinar H. Gunderson
who has benchmarked decompression speeds.

Grigori Goronzy provided the following stats for Deus Ex: Mankind
Divided start-up times on a Athlon X4 860k with a SSD:

No Cache                                 215 sec

Cold Cache zlib BEST_COMPRESSION         285 sec
Warm Cache zlib BEST_COMPRESSION         33 sec

Cold Cache zlib BEST_SPEED               264 sec
Warm Cache zlib BEST_SPEED               33 sec

Cold Cache no compression                266 sec
Warm Cache no compression                34 sec

The total cache size for that game is 48 MiB with BEST_COMPRESSION,
56 MiB with BEST_SPEED and 170 MiB with no compression.

These numbers suggest that it may be ok to go with Z_BEST_SPEED
but we should gather some actual decompression times before doing
so. Other options might be to do the compression in a separate
thread, this might allow us to use a higher compression algorithim
such as LZMA.

svga: fix crash regression since e027935a795

During the first update of the hw_clear_state atoms, we may not yet
have a current rasterizer state object.  So, svga->curr.rast may be
NULL and we crash.

Add a few null pointer checks to work around this.  Note that these
are only needed in the state update functions which are called for
'clear' validation.

mesa: Avoid read of uninitialized variable

The is_color_attachement variable is later read when handling two
separate error cases, where only one of the cases results in the
variable being initialized.

This can be avoided by giving the variable a safe default value.

mesa: Use _mesa_has_OES_geometry_shader() when validating draws

In validate_DrawElements_common() we need to check for OES_geometry_shader
extension to determine if we should fail if transform feedback is
unpaused. However current code reads ctx->Extensions.OES_geometry_shader
directly, which does not take context version into account. This means
that if the context is GLES 3.0, which makes the OES_geometry_shader
inapplicable, we would not validate the draw properly. To fix it, let's
replace the check with a call to _mesa_has_OES_geometry_shader().

Fixes following dEQP tests on i965 with a GLES 3.0 context:

dEQP-GLES3.functional.negative_api.vertex_array#draw_elements
dEQP-GLES3.functional.negative_api.vertex_array#draw_elements_incomplete_primitive

i965: Only flush the batchbuffer if we need to zero the SO offsets

If we don't have pipelined register access (e.g. Haswell before kernel
v4.2), then we can only implement EXT_transform_feedback by reseting the
SO offsets *between* batches. However, if we do have pipelined access to
the SO registers on gen7, we can simply emit an inline reset of the SO
registers without a full batch flush.

anv: do not subtract the base layer to compute depth in 3DSTATE_DEPTH_BUFFER

According to the PRM description of the Depth field:

  "This field specifies the total number of levels for a volume texture
   or the number of array elements allowed to be accessed starting at the
   Minimum Array Element for arrayed surfaces"

However, ISL defines array_len as the length of the range
[base_array_layer, base_array_layer + array_len], so it already represents
a value relative to the base array layer like the hardware expects.

v2: Depth is defined as a U11-1 field, so subtract 1 from
    the actual value (Jason)

This fixes a number of new CTS tests that would crash otherwise:
