Update kernel interface with new I915_GETPARAM ioctl entries for
pooled EU and min no. of eus in a pool. Add a wrapping function
for each parameter. Userspace drivers need these values when decide
the thread count. This kernel enabled pooled eu by default for BXT
and for fused down 2x6 parts it is advised to turn it off.
But there is another HW issue in these parts (fused
down 2x6 parts) before C0 that requires Pooled EU to be enabled as a
workaround. In this case the pool configuration changes depending upon
which subslice is disabled and the no. of eus in a pool is different,
So userspace need to know min no. of eus in a pool.
V2: use return value as the query results.
ret < 0 when error, ret = 0 when not support, and ret > 0 indicate
query results.(Chris)
V3: Correct V2 errors.

Sorry, I don't understand the android build system enough to say *which*
version of clang this effects, but either "clang-2812033" or
"clang-3016494" (probably the later).
But when 'sample' is undefined (ie. unitialized variable), the result is
not as well defined as it is with gcc. Instead use a typeof() cast with
a defined value (ie. zero).
This fixes a crash that was reported on android.

Since release.sh creates and pushes a libdrm-$VERSION tag for us,
there's no need to also have the user manually generating a $VERSION
tag as well.
I also dropped the "optional" part of distcheck. You shouldn't have
pushed master with a version bump that hasn't passed distcheck.

Currently only some Android Makefiles are included in the release tarball.
To be more consistent one could either add the remaining files or don't
ship Android Makefiles altogether.
According to Emil the Android folk doesn't use our release tarballs.
Thus it makes sense to remove those files from distribution which also
means less work for maintenance in the future.

Eventually we'll want a separate bo-cache for ringbuffer bo's, since
ringbuffer bo's get vmap'd on the kernel side, it is preferrable to
re-use them as ringbuffers rather than something else. Plus should
help to add madvise support if it is a bit better decoupled from bo
allocation (next patch).

Provide a way to insert a reference (ie. OUT_IB()) to a target ring,
executing all the cmds in the target ring from the start.
Sometimes the ringmarker stuff is just overkill. And it will won't
really work properly once we support multiple physical cmdstream buffers
per fd_ringbuffer. So in the future the old ringmarker related APIs
will be deprecated in a few releases.
