Implement a small abstraction interface to allow different versions of
VIC to be used transparently. An operations structure is selected based
on the VIC version number reported by the DRM_TEGRA_IOCTL_OPEN_CHANNEL
IOCTL.

All of the buffer object allocation functions use the same boilerplate
code. Move that code into a separate function that can be reused.

When opening a channel, allow a version number to be returned so that
userspace can parameterize based on it, rather than having to guess a
version from the environment.

These functions can be used to open channels to engines, manage job
submissions, create push buffers to store command streams in and wait
until jobs have been completed.

Changes in v2:
- automatically allocate buffer objects as required by pushbuffers
- pushbuffers can now have more than one associated buffer object
- add drm_tegra_pushbuf_prepare() function

This will prevent any more missing `#include "config.h"` bug, at the
cost of having to recompile some files that didn't need to be when
changing build options.

Helpful if your nm executable has a prefix based on the
architecture, for example.

This patch adds a complete meson build system, including tests and
install. It has the necessary hooks to allow it be used as a subproject
for other meson based builds such as mesa.

I get a few more symbols in my build tegra-libraries, so let's
include these in the whitelist as well.
While we're at it, update the comment at the top.

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.

These two functions are simple wrappers around the corresponding IOCTLs
and operate on drm_tegra_bo objects.

Add the libdrm_tegra helper library to encapsulate Tegra-specific
interfaces to the DRM.
Furthermore, Tegra is added to the list of supported chips in the
modetest and vbltest programs.
