freedreno/msm: remove reset of linked rings

The msm_cmd isn't refcount'd, so with stateobj rb's that have
independent lifecycle, this is no longer a safe thing to do.
Really, now that there is a bo-cache for rb's, fd_ringbuffer_reset()
should be deprecated because it adds a bunch of pointless complexity.

freedreno: remove deprecated ringmarker API

It's usage in mesa was removed more than two years ago.  And it stands
in the way of some optimizations needed to reduce the overhead of hw
stateobjs (ie. CP_SET_DRAW_STATE, where the # of cmds in the submit
ioctl goes up significantly).

libdrm: Allow dynamic drm majors on linux

To determine whether a device node is a drm device node or not, the code
currently compares the node's major number to the static drm major device
number.

This breaks the standalone vmwgfx driver on XWayland dri clients,
https://cgit.freedesktop.org/mesa/vmwgfx
and any future attempt to introduce dynamic device numbers for drm.

So instead of checking for the device major, instead check for the presence
of the /sys/dev/char/<major>:<minor>/device/drm directory.

intel: add generic functions to check PCI ID

This will allow platforms to reuse kernel IDs instead of manually
keeping them in sync. In most of the cases we only need to extend
IS_9XX().  Current platforms that fit this requirement can be ported
over to use this macro. Right now it's a nop since it doesn't have any
PCI ID added.

The i915_pciids.h header is in sync with kernel tree on
drm-tip 2018y-08m-20d-21h-41m-11s.

v2: - move to a separate .c so we can have the array in a single
      compilation unit
    - use a single array for all gens
    - add real functions to get or check gen by pciid
    - define our own pci device struct rather than inherit the one
      kernel uses: we can throw away most of the fields

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.)

xf86drm: fallback to normal path when realpath fails
