During anv_physical_device_init(), we opend the DRM device to do some
queries, then promptly closed it. Now we keep it open for the lifetime
of the anv_physical_device so that we can query it some more during
vkGetPhysicalDevice*Properties() [which will happen in follow-up
commits].
Because in a follow-up patch I need to do some non-trival teardown on
anv_physical_device. Currently, however, anv_physical_device_finish() is
currently a no-op that's just called in the right place.
Also, rename function fill_physical_device -> anv_physical_device_init
for symmetry.
Don't assume that $(top_srcdir)/.git is a directory. It may be a
gitlink file [1] if $(top_srcdir) is a submodule checkout or a linked
worktree [2].
[1] A "gitlink" is a text file that specifies the real location of
the gitdir.
[2] Linked worktrees are a new feature in Git 2.5.

The Vulkan spec says that pPhysicalDeviceCount is an out parameter if
pPhysicalDevices is NULL; otherwise it's an inout parameter.
Mesa incorrectly treated it unconditionally as an inout parameter, which
could have lead to reading unitialized data.
Don't enumerate devices in vkCreateInstance(). That's where global,
device-independent initialization should happen. Move device enumeration
to the more logical location, vkEnumeratePhysicalDevices().
Function fill_physical_device() has a 'path' parameter, and struct
anv_physical_device has a 'path' member. Sometimes these are used;
sometimes hardcoded "/dev/dri/renderD128" is used instead.
Be consistent. Hardcode "/dev/dri/renderD128" in exactly one location,
during initialization of the physical device.
Before values are pushed or annotated with a name, decoration, etc.,
they need to have an invalid type, NULL name, NULL decoration, etc.
ralloc zero's everything by accident, so this wasn't an issue in
practice, but we should be explicitly zero'ing it.
