This uses a meson builtin to handle -fvisibility=hidden. This is nice
because we don't need to track which languages are used, if C++ is
suddenly added meson just does the right thing.

Older kernels did not support `MSM_INFO_GET_IOVA`. But this is only
required for (a) clover (ie. `fd_set_global_binding()`) and drm paths
that are limited to newer kernels. So move the location of the assert
to fix new userspace on old kernels.

"softpin" mode was introduced in the same kernel as the 'DUMP' flag. So
if we are using the legacy non-softpin path, clear the dump flag. OTOH
the 'DUMP' flag isn't quite so needed on older kernels, since we would
get all cmdstream, even SDS stateobjs, dumped regardless, as they would
have cmd table entries.

For the piglit drawoverhead case, 5/18 of the objects' relocs were
duplicated. We can dedupe them at object create time (since objects are
long-lived) and avoid repeated relocation work at emit time.

Using non-write flags is pretty dubious -- it means the kernel tracking an
array of read-only consumers of the BO and having exclusive consumers wait
on each reader's fence. It allows multiple readers through dma-bufs to do
work in parallel, but at the cost of kernel CPU time and memory management
of the shared array. Other drivers have dropped this distinction since
dma-buf sharing is usually producer-consumer, not producer-two-consumers,
and the userspace and kernel space tracking is expensive.
For us, this lets us drop the flags passed in for relocs and tracked in
the ringbuffer reloc lists. The end result of the flags reduction work is
drawoverhead uniforms test throughput 2.37195% +/- 0.365579% (n=15)

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.

The existing structure dates back to when this code was part of libdrm,
and we wanted some of this not to be exposed as ABI between libdrm and
mesa. Now that this is no longer a constraint, inline things.

A cmdstream of size zero is invalid. But this can appear in various
places where we emit a pointer to state. This doesn't show up with
newer kernels (newer than v5.0) which use "softpin", but on earlier
kernels can result in:
[drm:msm_ioctl_gem_submit [msm]] *ERROR* invalid cmdstream size: 0
Since the pointer value doesn't matter in these cases, the easy solution
is just to not emit a cmds table entry in this case.

If nothing else, this will make problems with cmdstream getting blit
over with pixels easier to track down (ie. faults when it first happens
rather than strange failures later from corrupted cmdstream when a
stateobj is later reused).
(NOTE this somewhat depends on the kernel supporting the flag, and the
iommu implementation. But the worst case is just that the cmdstream
ends up writeable as before.)
