This will allow applications to use this feature without a device.
The first use case will be native context: we want VA address to
be managed by the guest (to avoid a round-trip to the host to only
generate a VA) but the amdgpu_device only exist on the host.

Until now VA management was tied to a device handle, but there's no
reason for this.
As a first step to export VA management outside of amdgpu_device,
this commit adds a new structure type holding the 4 va_mgr.

Device will be removed from dev_list when refcount reaches 0, so the
dev_mutex must be locked before decreasing reference otherwise there's
a race where this device is still in dev_list with refcount 0 which will
assert or crash in amdgpu_device_initialize trying to use this device
instead of creating new one.

This fixes the logic that decides if a node name is valid to use the
same length restrictions that are used in drmDeviceAlloc, which expects
node names to conform to a specific naming scheme (On OSes except
OpenBSD this means `/dev/dri/renderD123`). This addresses the problem of
node names that are longer than expected, while still allowing symlinks
to work.
I've also applied the same fix to the OpenBSD path, while bringing the
check that `snprintf` didn't error from OpenBSD to the main path.

If the user has some UDev rules in place that creates symlinks for
one of the card or render nodes, and the name of the symlink is
too long, then drmDeviceAlloc() ends up truncating the name of
the node.
This in turn results in chaos in different subsystems. E.g.
vulkaninfo dies early with this:
Code 0 : failed to stat DRM primary node /dev/dri/my-favorite- (VK_ERROR_INITIALIZATION_FAILED)
(if the symlink is called /dev/dri/my-favorite-card-node)

Cairo always uses native byte order for rendering.
Hence if the byte order of the frame buffer differs from the byte order
of the CPU, the frame buffer contents need to be byteswapped twice: once
before rendering, to convert to native byte order, and a second time
after rendering, to restore the frame buffer format's byte order.
Note that byte swapping is not done for ARGB32 formats, as for these
formats, byte order only affects the order of the red, green, and blue
channels, which we do not care about here.

but the code doesn't seem to support that in an easy way (like setting

To reduce the size and complexity of checks. require() allows combining
auto and enabled checks(), so that something like
```meson
x = get_option('feature')
y = false
if x.enabled()
if not condition
error(...)
endif
y = condition
endif
```
can be rewritten as:
```meson
y = get_option('feature').require(condition, error_message : ...).allowed()
```
require checks the condition, then if the feature is required it emits
an error with the given message otherwise it returns a disabled feature.
allowed then returns whether the feature is not disabled, and returns
that (ie, .allowed() == not .disabled()). This is especially helpful for
longer more complex conditions
