freedreno/ir3: invert is_same_type_mov() logic

Some instructions (like barriers) have no dst, which causes problems
with dereferencing a NULL dst.  Flip the logic around to reject opc's
that can't be a type of move first, to filter out those instructions.

swr: Fixed an uncommon freed-memory access during state validation

State validation is performed during clear and draw calls.  Validation
during clear was still accessing vertex buffer state.  When the currently
set vertex buffers are client arrays, this could lead to accessing freed
memory.  Such is the case with the VMD application.

Previously, vertex buffer validation depended on a dirty bit or the
draw info indicating an indexed draw.  This required special handling for
clears.  But, vertex buffer validation still occurred which was unnecessary
and wrong.

Now, only minimal validation is performed during clear, deferring the
remainder to the next draw.  And, by setting the dirty bit in swr_draw_vbo
for indexed draws, vertex buffer validation is only dependent upon a
single dirty bit.

This fixes a bug exposed by the VMD application when changing models.

gallium: add CAPs to support HW atomic counters. (v3)

This looks like an evergreen specific feature, but with atomic
counters AMD have hw specific counters they use instead of operating
on buffers directly. These are separate to the buffer atomics,
so require different limits and code paths.

I've left the CAP for atomic type extensible in case someone
else has a variant on this sort of thing (freedreno maybe?)
and needs to change it.

This adds all the CAPs required to add support for those atomic
counters, along with a related CAP for limiting the number of
output resources.

I'd like to land this and the st patch then I can start to
upstream the evergreen support for these and other GL4.x features.

v2: drop the ATOMIC_COUNTER_MODE cap, just use the return
from the HW counters. If 0 we use the current mode.

meson: Add script to use VERSION file for getting version

Meson has up until this point set it's version in the root meson.build
script, while the other build systems read the VERSION file. This is
just "one more thing" to duplicate between meson and every other build
system. This script is a simple "read, strip, print" sort of deal to
allow meson to read the VERSION file.

I chose to implement this in python since python is portable, and to
keep the meson.build script clean. This is also complicated by the fact
that the project() call *must* be the first non-comment,non-blank in the
toplevel meson.build script.
