This should help catch odd bugs at the callsites rather than much later
on with completely bogus bo indices.

Add a flag allowing Nouveau to specify that an object should be coherent
at allocation time. This is required for some class of objects like
fences which are randomly-accessed by both the CPU and GPU. This flag
instructs the kernel driver to make sure the object remains coherent
even on architectures for which coherency is not guaranteed by the bus.

Lost in 5ea6f1c32628887c9df0c53bc8c199eb12633fec, triggering fdo#89842.

Unlike the PRIME fd->handle interfaces, the GEM_OPEN interface doesn't
do anything at the kernel level to prevent this situation occuring,
and we end up with multiple GEM handles for a single kernel buffer.

A couple of files use ffs() without explicitly including strings.h.
Some systems will pull in ffs()'s declaration through another header
anyway, but not when compiling against bionic in AOSP master.

Some compilers (like the Oracle Studio), require that the function
declaration must be annotated with the same visibility attribute as the
definition. As annotating functions with drm_public is no longer
required just remove the macro.

With earlier commits we've annotated the private symbols, thus
we no longer require the -fvisibility=hidden CFLAGS.

They are less and easier to track than the public ones. The macro
drm_public will be going away by the end of the series.
