While I've closed off most races in a previous patch, a small race still existed
where importing then unreffing cound cause an invalid bo. Add a test for this case.
Racing sequence fixed:
- thread 1 releases bo, refcount drops to zero, blocks on acquiring nvdev->lock.
- thread 2 increases refcount to 1.
- thread 2 decreases refcount to zero, blocks on acquiring nvdev->lock.
At this point the 2 threads will clean up the same bo.

They have used them since day one, but the check was never there.
v2:
- Update the freedreno message (API is no longer experimental).
- Move the freedreno host_cpu detection next to the intel one.

Now that enabling freedreno doesn't automatically enable kgsl, lets
enable it by default. The drm/msm driver has been upstream for a
while now, and it's ABI is locked. So I don't think we need to keep
calling it experimental.

libdrm_freedreno currently supports two backends, 'msm' for the upstream
drm/msm driver, and 'kgsl' which supports (to some extent), the android/
downstream kgsl driver plus a sort of drm shim nonsense to get flink
names.
However, kgsl support is strictly on a best-effort basis. Different
android devices with different versions of kgsl may have different
abi's. And the existing kgsl interface (at least the parts of it that
we use) is completely broken for 64bit. Lets disable it by default lest
anyone actually try to use it.

By default all symbols will be hidden via the VISIBILITY_CFLAGS. The

This patch adds library and test application for g2d gpu(fimg2d).
The fimg2d hardware is a 2D graphics accelerator(G2D) that
supports Bit Block Transfer(BitBLT).
The library includes the following primitive drawing operations:
.solid fill - This operation fills the given buffer with
the given color data.
.copy - This operation copies contents in source buffer to
destination buffer.
.copy_with_scale - This operation copies contents in source buffer
to destination buffer scaling up or down properly.
.blend - This operation blends contents in source buffer with
the ones in destination buffer.
And the above operations uses gem handle or user space address
allocated by malloc() as source or destination buffer.
And the test application includes just simple primitive drawing
tests with the above library.
And the guide to test is as the following,
"#exynos_fimg2d_test -s connector_id@crtc_id:mode"
With this above simple command, four primitive drawing operations
would be called step by step and also rendered on the output device
to the given connector and crtc id.

The libdrm_freedreno helper layer for use by xf86-video-freedreno,
fdre (freedreno r/e library and tests for driving gpu), and eventual
gallium driver for the Adreno GPU. This uses the msm gpu driver
from QCOM's android kernel tree.
Note that current msm kernel driver is a bit strange. It provides a
DRM interface for GEM, which is basically sufficient to have DRI2
working. But it does not provide KMS. And interface to 2d and 3d
cores is via different other devices (/dev/kgsl-*). This is not
quite how I'd write a DRM driver, but at this stage it is useful for
xf86-video-freedreno and fdre (and eventual gallium driver) to be
able to work on existing kernel driver from QCOM, to allow to
capture cmdstream dumps from the binary blob drivers without having
to reboot. So libdrm_freedreno attempts to hide most of the crazy.
The intention is that when there is a proper kernel driver, it will
be mostly just changes in libdrm_freedreno to adapt the gallium
driver and xf86-video-freedreno (ignoring the fbdev->KMS changes).
So don't look at freedreno as an example of how to write a libdrm
module or a DRM driver.. it is just an attempt to paper over a non-
standard kernel driver architecture.
v1: original
v2: hold ref's to pending bo's (because qcom's kernel driver doesn't),
various bug fixes, add ringbuffer markers so we can emit IB's to
portion of ringbuffer (so that gallium driver can use a single
ringbuffer for both tile cmds and draw cmds.

This fixes all the out-of-tree build-failures with manpages and uses a
.man_fixup file to avoid overriding man-pages on every build.
Manpages are only built if xsltproc is found and the stylesheets are
available locally. You can disable building manpages with
--disable-manpages so the quite expensive xsltproc procedure can be
skipped.

There can be scenarios, especially when re-importing an existing buffer,
where you end up with multiple 'struct omap_bo's wrapping a single GEM
object handle. Which causes badness when the first of the evil-clones
is omap_bo_del()'d.
To do this, introduce reference counting and a hashtable to track the
handles per fd.
First, to avoid bo's slipping through the crack if multiple 'struct
omap_device's are created for one drm fd, a hashtable mapping drm
fd to omap_device, and the omap_device itself is reference counted.
Per omap_device, we keep a handle_table mapping GEM handle to omap_bo.
When buffers are imported from flink name or dmabuf fd, the handle
table is consulted, and if an omap_bo already exists, it's refcnt is
incremented and it is returned. For good measure, to avoid the
handle_table being deleted before the omap_bo is freed, the omap_bo
holds a reference to the omap_device.
TODO: check the overhead of the hashtable. If too much we could maybe
get away with only tracking exported and imported bo's in the table.
TODO: all the import/export flink/dmabuf operations are generic DRM
ioctls. Really all this functionality could be handled by a generic
drm_bo and drm_device "base class" that could be extended by omap,
exynos, etc. That would also allow more common userspace code by
avoiding artificial libdrm_omap dependencies.
