Wayland buffers coming from wl_drm use the WL_DRM_FORMAT_* enums, which
are identical to GBM_FORMAT_*. Similarly, FD imports do not need to
convert between GBM and DRI FourCC, since they are (almost) completely
compatible.
This widens the formats accepted by gbm_bo_import() when importing
wl_buffers; previously, only XRGB8888, ARGB8888, RGB565 and YUYV were
supported.

The actual offset returned is uint32_t, however int64_t was used as the
return type from gbm_bo_get_offset to allow negative returns to signal
errors to the caller.
In case of an error getting the offset, the user will also be unable to
get the handle/FD, and thus have nothing to offset into. This means that
returning 0 as an error value is harmless, allowing us to change the
return type to uint32_t in order to avoid signed/unsigned confusion in
callers.

gbm: Get modifiers from DRI
To accomplish this, two new query tokens are added to the extension:
__DRI_IMAGE_ATTRIB_MODIFIER_UPPER
__DRI_IMAGE_ATTRIB_MODIFIER_LOWER
The query extension only supported 32b queries, and modifiers are 64b,
so we needed two of them.
NOTE: The extension version is still set to 13, so none of this will
actually be called.

The idea behind modifiers like this is that the user of GBM will have
some mechanism to query what properties the hardware supports for its BO
or surface. This information is directly passed in (and stored) so that
the DRI implementation can create an image with the appropriate
attributes.
A getter() will be added later so that the user GBM will be able to
query what modifier should be used.
Only in surface creation, the modifiers are stored until the BO is
actually allocated. In regular buffer allocation, the correct modifier
can (will be, in future patches be chosen at creation time.
v2: Make sure to check if count is non-zero in addition to testing if
calloc fails. (Daniel)
v3: Remove "usage" and "flags" from modifier creation. Requested by
Kristian.
v4: Take advantage of the "INVALID" modifier added by the GET_PLANE2
series.
v5: Don't bother with storing modifiers for gbm_bo_create because that's
a synchronous operation and we can actually select the correct modifier
at create time (done in a later patch) (Jason)
v6: Make modifier condition outside the check so that dri_use will work
properly (Jason)

mapImage/unmapImage functions or existing internal mapping for dumb

This new gbm entry point allows writing data into a gbm bo. The bo has
to be created with the GBM_BO_USE_WRITE flag, and it's only required to
work for GBM_BO_USE_CURSOR_64X64 bos.
The gbm API is designed to be the glue layer between EGL and KMS, but there
was never a mechanism initialize a buffer suitable for use with KMS
hw cursors. The hw cursor bo is typically not compatible with anything EGL
can render to, and thus there's no way to get data into such a bo.
gbm_bo_write() fills that gap while staying out of the efficient
cpu->gpu pixel transfer business.

The idea here is to be able to create an egl window surface from a
gbm_surface. This avoids the need for the surfaceless extension and
lets the EGL platform handle buffer allocation, while keeping the user
in charge of somehow presenting the buffers (using kms page flipping,
for example).
gbm_surface_lock_front_buffer() locks a surface's front buffer and
returns a gbm bo representing it. This bo should later be returned
to the gbm surface using gbm_surface_release_buffer().
GBM needs the buffer format in order to communicate with DRM and clients
for things like scanout.
So track the DRI format requested in the various back ends and use it to
return the DRI format back to GBM when requested. GBM will then map
this into the GBM surface type (which is in turn based on the DRM fb
format list).
