The RADEON_GEM_USERPTR_ANONONLY flag is hardcoded here which excludes
shared memory pages. DRM is actually capable of supporting shared file-
backed memory, but only if it's read-only. This mutability intent has to
be conveyed through the stack, so a flags argument is added to the winsys
regime to pass RADEON_FLAG_READ_ONLY.

Instead of allocating cpu_storage in threaded_resource_init, defer the
allocation to first use (in tc_buffer_map).
This avoids needless memory allocation if tc_buffer_disable_cpu_storage is
called before tc_buffer_map.
map_buffer_alignment is stored and serves as a "can cpu_storage be used" flag.

This removes resource_copy_region for BufferSubData. Drivers have to opt in
to use this.
See the comment in the header file.

When this flag is set, u_threaded_context will try not to map it directly
for better buffer placement. It's set by drivers when visible VRAM is too
small.

tc already calculates all the rebinding that needs to be done on a given
context, so (some of) this info can be passed on to drivers to enable
optimizations

It's only used by buffers and only zink uses it privately for textures too.
This is part of removing u_resource_vtbl.

Alignments are always 2^n, so store n = log2(alignment). The next commit
will take advantage of the saved space.

This will allow removing the winsys pointer from buffers.
The amdgpu winsys adds dummy_ws to get radeon_winsys because there can be
no radeon_winsys around (e.g. while amdgpu_winsys is being destroyed), but
we still need some way to call buffer functions.

There are many issues with SDMA across many generations of hardware.
A recent example is that gfx10.3 suffers from random GPU hangs if
userspace uses SDMA.
