libdrm: Fix issue about differrent domainID but same BDF

For multiple GPUs which has the same BDF, but has different domain ID,
the drmOpenByBusid will return the wrong fd when startx.

The reproduce sequence as below:
1. Call drmOpenByBusid to open Card0, then will return the right fd0, and the
fd0 is master privilege;
2. Call drmOpenByBusid to open Card1. In function drmOpenByBusid, it will
open Card0 first, this time, the fd1 for opening Card0 is not master
privilege, and will call drmSetInterfaceVersion to identify the
domain ID feature, as the fd1 is not master privilege, then drmSetInterfaceVersion
will fail, and then won't compare domain ID, then return the wrong fd for Card1.

Solution:
First loop search the best match fd about drm 1.4.

xf86drm: Add drmIsMaster()

We can't use drmSetMaster to query whether or not a drm fd is master
because it requires CAP_SYS_ADMIN, even if the fd *is* a master fd.

Pick DRM_IOCTL_MODE_ATTACHMODE as a long-deprecated ioctl that is
DRM_MASTER but not DRM_ROOT_ONLY as the probe by which we can detect
whether or not the fd is master.

This is useful for code that might get master by open()ing the drm device
while no other master exists, but can't call drmSetMaster itself because
it's not running as root or is in a container, where container-root isn't
real-root.

v2: Use the AUTH_MAGIC request rather than MODE_ATTACHMODE, as it's more
    clearly related to master status.

v3: [Emil] Don't expose internals, check for -EACCES.

Seemingly the 64-bit int is always aligned to 8 in LP64.
But this is not hold in LP32.

Consequently sizeof(gralloc_drm_handle_t) are different
between LP64 (which is 18 ints) and LP32 (which is 16 ints).
As a result, 32-bit apps will crash in 64-bit OS since the

is true.

Fix it by always aligning 64-bit int to 8. Besides, to avoid
additional padding, just exchange the order of data_owner
and modifier. It aligns modifier to 8 natually.

Add basic CONTRIBUTING file

I picked up a bunch of the pieces from wayland's version:

https://gitlab.freedesktop.org/wayland/wayland/blob/master/CONTRIBUTING.md

The weston one is fairly similar. Then I rather massively trimmed it
down since in reality libdrm is a bit a dumping ground with very few
real rules. The commit rights and CoC sections I've copied verbatim
from igt respectively drm-misc. Weston/Wayland only differ in their
pick of how many patches you need (10 instead of 5). I think for
libdrm this is supremely relevant, since most everyone will get their
commit rights by contributing already to the kernel or mesa and having
commit rights there already.

Anyway, I figured this is good to get the rules documented, even if
there's mostly not many rules.

Note: This references maintainers in a MAINTAINERS file, which needs
to be created first.

Note: With the gitlab migration the entire commit rights process is
still a bit up in the air. But gitlab commit rights and roles are
hierarchical, so we can do libdrm-only maintainer/commiter roles
("Owner" and "Developer" in gitlab-speak). This should avoid
conflating libdrm roles with mesa roles, useful for those pushing to
libdrm as primarily kernel contributors.

v2: Comments from Emil:
- Recommend subject prefix.
- Fix copypaste fumbles, this isn't igt/wayland ...

v3: Comments from Marek:
- libdrm moved to mesa, update the document. Atm the entire account
  request situation is entirely not clear for gitlab and mesa
  projects, so that's a bit up in the air. Also, should probably send
  an announcement to dri-devel@, which didn't happen.
- amd folks don't submit their patches to dri-devel, document that.
  Probably applies to other drivers too.

v4: Comments from Rob:
- Also include kernel/userspace in the commit counts criteria, due to
  libdrm's special role as a glue library.

v5: Summarize the irc discussion on gitlab roles in the commit message
a bit.

v6: Some grammer stuff from Eric E.

v7: Use --local in git config (Eric E.)
