It hasn't really mattered until now, as we keep a separate cache for
cmdstream (which is FD_BO_GPU_READONLY), and the only other flag so
far is FD_BO_SCANOUT (which the bo cache probably messes up, but it
does not matter on most hw, and on hw where it does the scanout buffer
will be imported (and therefore won't end up in the bo cache).
But when we add cached-coherent (or if we wanted to use GPU_READONLY
more) it starts to matter.

Add a per-fd_pipe fence "timeline" so we can detect cases where we don't
need to call into the kernel to determine if a fd_bo is still busy.
This reuses table_lock, rather than introducing a per-bo lock to protect
fence state updates because (a) the common / hotpath pattern is to
update fences on a lot of objects, but checking the fence state of a
single object is less common, and (b) because we already hold the table
lock in common spots where we need to check the bo's fence state (ie.
allocations from the bo-cache).

This is a bit over-paranoid, and can cause drm device fd leaks if there
is a bo leak somewhere. Which is kind of a worse outcome.
This "fixes" a fd leak seen in:
dEQP-EGL.functional.query_context.get_current_display.*
dEQP-EGL.functional.query_context.get_current_context.*
dEQP-EGL.functional.query_context.get_current_display.*
(Still tracking down the root leak)

It's silly to have all the reloc emitters passing around FD_RELOC_READ
when you have to have it set on all relocs (that don't include WRITE,
which implies read) for the kernel to actually track the fences on the BO.

So that we can re-use at least parts of it for vulkan driver, and so
that we can move ir3 to a common location (which uses fd_bo to allocate
storage for shaders)
