This adds a function to get a drmDevicePtr from a dev_t identifier
of a device. This is useful for Wayland that uses these to identify
devices over the protocol.
This is done by taking the implementation of drmGetDevice2, and removing
the call to fstat to find the dev_t.

Add support for parsing IN_FORMATS property blobs. Providing libdrm
with this functionality helps to standardise how user-space reads
kernel blobs and decreases duplication on the client side.
drmModeFormatModifierBlobIterNext() allows the caller to view
formats and associated modifiers given a valid property blob.
An example is available inside the libdrm unit test, modetest.c.

No need to have two branches depending on DRM_MODE_PROP_EXTENDED_TYPE.
We can just use drmModeGetPropertyType instead.
This does introduce a slight change: previously, drm_property_type_is()
could be called with non-type flags such as IMMUTABLE. However no user
seems to do this (checked KWin/Mutter/Sway/Weston/Xorg).

There is this long standing nit of igt/tools/intel_error_decode asserting
when you feed it an error state from a GPU the local libdrm does not know
of.
To fix this I need a tweak in drm_intel_decode_context_alloc to make it
not assert but just return NULL (which seems an already possible return

Some changes were omitted, e.g., to nouveau_drm.h, i915_drm.h, and
msm_drm.h, as the nouveau and i915 changes looked to me as if they
could break compatibility or require other compatibility fixes to
libdrm which i can not judge. msm_drm.h broke the build, as there
are definitely changes needed to libdrm's msm support code.

As format modifiers can be encoded in quite complex forms, the static
table previously added is not sufficient to retrieve, extract and decode
the token formats to a human-readable string. This patch introduces a
vendor specific callback which could be used to perform an additional
search to match up with vendor encoding scheme, which, will be used
first, before resorting to searching the static table.
With it, add support for decoding the ARM format modifiers.
Signed-off-by: Marius Vlad <marius.vlad@collabora.com>
Introduces two new methods to retrieve a human readable representation of a
format modifier:
drmGetFormatModifierName() - returns a format modifier as a string,
from a token modifier
drmGetFormatModifierVendor() - returns the vendor as a string, from a
token modifier
and the fourcc_mod_get_vendor macro that returns the vendor.
New format modifiers added in drm_fourcc.h uapi kernel header should be
sync'ed up with libdrm and should include a human readable
representation for that format modifier, in order to display it
correctly as a string.
That happens with the help of a python script that reads up drm_fourcc
header file and outputs a static table comprised of token modifiers
alongside a vendor table (Suggested-by Simon Ser <contact@emersion.fr>).
The reason for doing it in libdrm is to have a unified place instead of each
user of libdrm having a way to keep track of the format modifiers.
With this patch, modetest has also been modified to make use of it.
