[mesa v3 5/9] nouveau: fix screen creation failure paths

[Ben Skeggs]

From: Ben Skeggs <bskeggs@redhat.com>

The winsys layer would attempt to cleanup the nouveau_device if screen
init failed, however, in most paths the pipe driver would have already
destroyed it, resulting in accesses to freed memory etc.

This commit fixes the problem by allowing the winsys to detect whether
the pipe driver's destroy function needs to be called or not.

[mesa v3 6/9] nouveau: remove use of deprecated nouveau_device_wrap()

[Ben Skeggs]

From: Ben Skeggs <bskeggs@redhat.com>

Switching to the newer libdrm entry-points tells libdrm that it's OK to
make use of newer kernel interfaces.

We want to be able to isolate any bugs to either the interfaces changes,
or the use of NVIF itself.  As such, this commit has a slight hack which
forces libdrm to continue using the older kernel interfaces.

[mesa v3 7/9] nv50: fix g98+ vdec class allocation

[Ben Skeggs]

From: Ben Skeggs <bskeggs@redhat.com>

The kernel previously exposed incorrect classes for some of the chipsets
that this code supports.  It no longer does, but the older object ioctls
have compatibility to avoid breaking userspace.

This needs to be fixed before switching over to the newer interfaces.

Rather than hardcoding chipset->class like the rest of the driver does,
this makes use of (new) sclass queries to determine what's available.

v2.
- update to use symbolic class identifier from <nvif/class.h>

[mesa v3 8/9] nvc0: remove use of deprecated sw class identifier

[Ben Skeggs]

From: Ben Skeggs <bskeggs@redhat.com>

Also emits a method to properly bind the class to a subchannel, which
was missing previously.  The kernel currently doesn't care, but this
will break if it ever decides to (ie. to support multiple sw classes).
