This lock is used to serialize much more than just the lookup tables. In
fact it's used for all device global state including the bo cache. Rename
it to better reflect its real usage.

When destroying a BO with a userspace managed address and thus freeing
the VMA space, we need to make sure that the BO isn't in use by any
active submit anymore, as the kernel will rightfully reject the next
submit that re-uses the still active VMA. Keep the BO alive as long
as it isn't fully idle to prevent the VMA being reused prematurely.

We use the variable from gallium but fall back to a weak symbol
in case there's usage out of galllium in the future.

If softpin is available on the kernel side, we transparently replace the
relocs with self-managed GPU virtual addresses. This allows to skip some
work at the kernel side, as it doesn't need to touch the command stream
anymore before submitting it to the hardware.
