Some platforms (such as Macs using OF) can have more information in the
uevent file thus reading only the first 128 might not be sufficient.
Bump it to 512, which "should be enough for everybody" ;-)

As well as allowing a hexadecimal PCI ID number, the
INTEL_DEVID_OVERRIDE environment variable can now contain one of a few
short codenames. The codenames are stored in a small table to map them
to a corresponding PCI ID. This makes it easier to use without having
to look up the PCI IDs manually.
The PCI IDs used are the same as those chosen for the -p option of
run.c in shader-db but SKL has been added as well.

Rather than cut/pasting these couple ioctl wrappers everywhere, just
stuff them as static-inline into a header.
This is probably mostly used from mesa, but some drivers, test apps, etc
may also want to use it from libdrm.
v2: handle EINTR, add sync_accumulate() based on #dri-devel discussion,
etc

A slightly confused copy'n'paste from the open path where we pass in

Walking a linear list to find a matching PRIME handle or flinked name
does not scale and becomes a major burden with just a few objects.
That said, the fixed size hash is not much better, it just buckets the
look into a few separate chains rather than one long one.

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.
