It is possible to hit a race condition in create_from_prime, when trying
to import a BO that's currently being freed. In case of prime sharing
we'll succesfully get a handle, but fail on get_tiling call, potentially
confusing the caller (and requiring different locking scheme than with
sharing using flink). Wrap fd_to_handle with struct_mutex to force
a more consistent behaviour between prime/flink, convert fprintf to DBG
when handling errors.
(From Chris:
The race is that the kernel returns us the same file-private handle as
the first thread, but that first thread is about to call gem_close
(thereby removing the handle from the file completely) and does so
between us acquiring the handle and taking the mutex. If we take
the mutex, then we acquire the refcnt on the bo prior to the first
thread completing its unref (and so preventing the early close). Or we
acquire the handle after the earlier close, in which case we are the new
owner.

In case of YF/YS tiled buffers libdrm need not know about the tiling
format because these buffers don't have hardware support to be tiled
or detiled through a fenced region. But, libdrm still need to know
about buffer alignment restrictions because kernel uses it when
resolving the relocation.
Mesa uses drm_intel_gem_bo_alloc_for_render() to allocate Yf/Ys buffers.
So, use the passed alignment value in this function to initialize the
align variable in drm_intel_bo. Note that we continue ignoring the
alignment value passed to drm_intel_gem_bo_alloc() to follow the
previous behavior.
V2: Add a condition to avoid allocation from cache. (Ben)

In order to use userptr, the kernel tracks the owner's mm with a
mmu_notifier. Setting that is very expensive - it involves taking all
mm_locks and a stop_machine(). This tracking lives only for as long as
the client is using userptr objects - so if the client allocates then
frees a userptr in a loop, we will be executing that heavyweight setup
everytime. To ammoritize this cost, just leak the test bo and the single
backing page we use for detecting userptr.

Update kernel interface with new I915_GETPARAM ioctl entries for
subslice total and EU total. Add a wrapping function for each
parameter. Userspace drivers need these values when constructing
GPGPU commands. This kernel query method is intended to replace
the PCI ID-based tables that userspace drivers currently maintain.
The kernel driver can employ fuse register reads as needed to
ensure the most accurate determination of GT config attributes.
This first became important with Cherryview in which the config
could differ between devices with the same PCI ID.
The kernel detection of these values is device-specific. Userspace
drivers should continue to maintain ID-based tables for older
devices which return ENODEV when using this query.
v2: remove unnecessary include of <stdbool.h> and increment the
I915_GETPARAM indices to match updated kernel patch.

When using Mesa and LibVA in the same process, one would like to be
able bind buffers from the output of the decoder to a GL texture
through an EGLImage.
LibVA can reuse buffers allocated by Gbm through a file descriptor. It
will then wrap it into a drm_intel_bo with
drm_intel_bo_gem_create_from_prime().
The problem at the moment is that both library get a different
drm_intel_bufmgr object when they call drm_intel_bufmgr_gem_init()
even though they're using the same drm file descriptor. As a result,
instead of manipulating the same buffer object for a given file
descriptor, they get 2 different drm_intel_bo objects and 2 different
refcounts, leading one of the library to get errors from the kernel on
invalid BO when one of the 2 library is done with a shared buffer.
This patch modifies drm_intel_bufmgr_gem_init() so, given a file
descriptor, it will look for an already existing drm_intel_bufmgr
using the same file descriptor and return that object.

Export include dir from libdrm
BZ: 116218
Google introduced new method of specifying include path(s)
between modules. This allows a module to include header from a
library without directly specifyining by includer the path where
headers are located.
The method requires from library that holds headers to export
include path(s) in LOCAL_EXPORT_C_INCLUDE_DIRS variable.
These exported include path(s) are automatically added to
include path(s) of modules that have name of the library in the
LOCAL_SHARED_LIBRARIES or LOCAL_STATIC_LIBRARIES list.
This change sets LOCAL_EXPORT_C_INCLUDE_DIRS to folders that
contain headers file that used by other modules in order to
export these paths.
