This patch adds display (primary) memory validation during modeset
check. Display memory validation are applicable to both SOU and STDU,
so allow both display unit to undergo this check.
Also added check for SVGA_CAP_NO_BB_RESTRICTION capability which lifts
bounding box restriction for STDU.

vmw_kms_atomic_check_modeset() is currently checking config using the
legacy state, which is updated after a commit has happened.
This means vmw_kms_atomic_check_modeset() will reject an invalid config
on the next update rather than the current one.
Fix this by using the new states for config checking

Previously when evicting resources we were unconditionally calling
ttm_eu_reserve_buffers with a NULL ww acquire context. That meant all
buffer object reserves were done using trylock semantics.
That makes sense when evicting during resource validation, because then
there already are a number of buffers reserved and using waiting locks
would cause lockdep errors.
That's not the case when unconditionally evicting all resources as part
of driver takedown or hibernation, so in that code path, make sure
we have a ww acquire context to get waiting lock buffer object reserve
semantics.

Initially vmware buffer objects were only used as DMA buffers, so the name
DMA buffer was a natural one. However, currently they are used also as
dumb buffers and MOBs backing guest backed objects so renaming them to
buffer objects is logical. Particularly since there is a dmabuf subsystem
in the kernel where a dma buffer means something completely different.
This also renames user-space api structures and IOCTL names
correspondingly, but the old names remain defined for now and the ABI
hasn't changed.
There are a couple of minor style changes to make checkpatch happy.

For modeset locks we don't expect a high number of contending

The current Wound-Wait mutex algorithm is actually not Wound-Wait but
Wait-Die. Implement also Wound-Wait as a per-ww-class choice. Wound-Wait
is, contrary to Wait-Die a preemptive algorithm and is known to generate
fewer backoffs. Testing reveals that this is true if the
number of simultaneous contending transactions is small.
As the number of simultaneous contending threads increases, Wait-Wound
becomes inferior to Wait-Die in terms of elapsed time.
Possibly due to the larger number of held locks of sleeping transactions.
Update documentation and callers.

Drivers such as vc4 don't initialize mode_config.funcs until later in
initialization, but we know they're atomic since they've got the flag
set. This avoids oopsing on dereferencing funcs in the new atomic
methods sanity checks.
I moved the atomic check function down below the core flag check, to
avoid needing a prototype.
