Currently we have two sets of functions for bit counts, one in gallium
and one in core mesa. The ones in core mesa are header only in many
cases, since they reduce to "#define _mesa_bitcount popcount", but they
provide a fallback implementation. This is important because 32bit msvc
doesn't have popcountll, just popcount; so when nir (for example)
includes the core mesa header it doesn't (and shouldn't) link with core
mesa. To fix this we'll promote the version out of gallium util, then
replace the core mesa uses with the util version, since nir (and other
non-core mesa users) can and do link with mesautils.

One of the pains of implementing a gallium driver is filling in a million
pipe caps you don't know about yet when you're just starting out. One of
the pains of working on gallium is copy-and-pasting your new PIPE_CAP into
each driver. We can fix both of these by having each driver call into the
default helper from their default case, so that both sides can ignore each
other until they need to.
v2: fix i915g build, revert swr change to avoid breaking scons build
(https://travis-ci.org/anholt/mesa/jobs/419739857)
v3: Rebase on 3 new gallium caps.

Now that all the build scripts are compatible with both Python 2 and 3,
we can flip the switch and tell Meson to use the latter.
Since Meson already depends on Python 3 anyway, this means we don't need
two different Python stacks to build Mesa.

This seems to have been missed in the move from autotools
This fixes the following build issue:
../src/gallium/auxiliary/vl/vl_winsys_dri.c:34:10: fatal error: X11/Xlib-xcb.h: No such file or directory
#include <X11/Xlib-xcb.h>

In the old days (0.42.x), when mesa's meson system was written the
recommendation for handling conditional dependencies was to define them
as empty lists. When meson would evaluate the dependencies of a target
it would recursively flatten all of the arguments, and empty lists would
be removed. There are some problems with this, among them that lists and
dependencies have different methods (namely .found()), so the
recommendation changed to use `dependency('', required : false)` for
such cases. This has the advantage of providing a .found() method, so
there is no need to do things like `dep_foo != [] and dep_foo.found()`,
such a dependency should never exist.
I've tested this with 0.42 (the minimum we claim to support) and 0.45.
On 0.45 this removes warnings about comparing unlike types, such as:
meson.build:1337: WARNING: Trying to compare values of different types
(DependencyHolder, list) using !=.
v2: - Use dependency('', required : false) instead of
declare_dependency(), the later will always report that it is
found, which is not what we want.

This makes the dependencies easier to manage, since each media target
doesn't need to worry about linking to half a dozen libraries.

This creates two new internal dependencies, idep_nir_headers and
idep_nir. The former encapsulates the generation of nir_opcodes.h and
nir_builder_opcodes.h and adding src/compiler/nir as an include path.
This ensures that any target that needs nir headers will have the
includes and that the generated headers will be generated before the
target is build. The second, idep_nir, includes the first and
additionally links to libnir.
This is intended to make it easier to avoid race conditions in the build
when using nir, since the number of consumers for libnir and it's
headers are quite high.

Add a new helper that drivers can use to emulate various things that
need special handling in particular in transfer_map:
1) z32_s8x24.. gl/gallium treats this as a single buffer with depth
and stencil interleaved but hardware frequently treats this as
separate z32 and s8 buffers. Special pack/unpack handling is
needed in transfer_map/unmap to pack/unpack the exposed buffer
2) fake RGTC.. GPUs designed with GLES in mind, but which can other-
wise do GL3, if native RGTC is not supported it can be emulated
by converting to uncompressed internally, but needs pack/unpack
in transfer_map/unmap
3) MSAA resolves in the transfer_map() case
v2: add MSAA resolve based on Eric's "gallium: Add helpers for MSAA
resolves in pipe_transfer_map()/unmap()." patch; avoid wrapping
pipe_resource, to make it possible for drivers to use both this
and threaded_context.

This creates a dependency on this header being generated before trying
to compile any of these targets, as well as passing the correct -I to
the compiler to ensure it's included correctly.
