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.

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.

This option finds all connected connector and then sets its preferred
mode on it. If no preferred mode is available, first mode is used.
This option must be set w/o any mode or plane.
This allows for a quick test on all connected outputs.
Loosely based on the work by Ezequiel Garcia <ezequiel@collabora.com>
Changes since Ezequiel's work:
- implement atomic codepath
- set all connectors
- pick correct crtc
- don't set -r by default
- nearly identical output in atomic and non-atomic codepaths
v2:
- Use the crtc->crtc_id, instead of the plane's current crtc_id

Add function to derive floating value of vertical
refresh rate from drm mode using pixel clock,
horizontal total size and vertical total size.
Use this function to find suitable mode having vrefresh
value which is matching with user provided vrefresh value.
If user doesn't provide any vrefresh value in args then
update vertical refresh rate value in pipe args using this
function.
Also use this function for printing floating vrefresh while
dumping all available modes.
This will give more accurate picture to user for available modes
differentiated by floating vertical refresh rate and help user
select more appropriate mode using suitable refresh rate value.
V4:
1) While setting mode, print mode name and vrefresh using struct
drmModeModeInfo instead of struct pipe_args.
2) Revert back to using a float value instead of float *
for vrefresh arg in connector_find_mode().
V3:
1) Change name of function used to derive refresh rate.
V2:
1) Don't use inline function for deriving refresh rate from mode.
2) If requested mode not found, print refresh rate only
if user had provided it in args.

For the scenario where user may require to modeset with a mode
supporting a fractional value for vertical refresh-rate,
appropriate mode can be selected by searching for mode
having matching fractional vertical refresh rate using
below equation.
vrefresh = (1000 * pixel clock) / (htotal * vtotal) Hz.
We do this way since driver doesn't return float value of vrefresh
as it use int for vrefresh in struct drm_mode_info, but we can derive
the actual value using pixel clock, horizontal total size and
vertical total size values.
So for e.g. if user want to select mode having 59.94 Hz as refresh rate
then with this patch it be can done as shown in below command,
given there is an appropriate mode is available :
modetest -M xlnx -s 39:1920x1080-59.94@BG24 -v
NOTE: Above command was tested on xilinx DRM driver with DP
monitor which was supporting mode having 59.94 Hz refresh rate.
V2: Update commit message
V3: Update with below changes as per review comments :
1) Use epsilon for vrefresh comparison
2) Use implicit type-casting wherever possible
V4: Keep patch version history on main commit message

The existing format modifier definitions were merged prematurely, and
recent work has unveiled that the definitions are suboptimal in several
ways:
- The format specifiers, except for one, are not Tegra specific, but
the names don't reflect that.
- The number space is split into two, reserving 32 bits for some
"parameter" which most of the modifiers are not going to have.
- Symbolic names for the modifiers are not using the standard
DRM_FORMAT_MOD_* prefix, which makes them awkward to use.
- The vendor prefix NV is somewhat ambiguous.
Fortunately, nobody's started using these modifiers, so we can still fix
the above issues. Do so by using the standard prefix. Also, remove TEGRA
from the name of those modifiers that exist on NVIDIA GPUs as well. In
case of the block linear modifiers, make the "parameter" smaller (4
bits, though only 6 values are valid) and don't let that leak into any
of the other modifiers.
Finally, also use the more canonical NVIDIA instead of the ambiguous NV
prefix.
This is based on commit 5843f4e02fbe86a59981e35adc6cabebee46fdc0 from
Linux v4.16-rc1 and also updates modetest to use the new defines.
