This allows consumers of libdrm as a subproject to use the simpler
`dependency('libdrm', fallback : 'libdrm')` syntax, as the libdrm build
files already tell meson that they override a dependency called
"libdrm".

This fixes boot failures with Android (likely w/ closed source

Commit c86dabfc9f ("omap: zero is a valid fd number, treat it as
such") corrected checks for valid file descriptors, but the OMAP buffer
object code initializes the DMA-BUF file descriptor to 0 (as a result of
calloc()'ing the structure). Obviously this isn't going to work because
subsequent code will try to use file descriptor 0 (most likely stdin at
that point) as a DMA-BUF. It may also try and close stdin when a buffer
object is destroyed.
Fix this by initializing the DMA-BUF file descriptor to -1, properly
marking it as an invalid file descriptor.

omap_drm.h uses data type defined in stdint.h, but that header was
not included.

compiler c flags.

There can be scenarios, especially when re-importing an existing buffer,
where you end up with multiple 'struct omap_bo's wrapping a single GEM
object handle. Which causes badness when the first of the evil-clones
is omap_bo_del()'d.
To do this, introduce reference counting and a hashtable to track the
handles per fd.
First, to avoid bo's slipping through the crack if multiple 'struct
omap_device's are created for one drm fd, a hashtable mapping drm
fd to omap_device, and the omap_device itself is reference counted.
Per omap_device, we keep a handle_table mapping GEM handle to omap_bo.
When buffers are imported from flink name or dmabuf fd, the handle
table is consulted, and if an omap_bo already exists, it's refcnt is
incremented and it is returned. For good measure, to avoid the
handle_table being deleted before the omap_bo is freed, the omap_bo
holds a reference to the omap_device.
TODO: check the overhead of the hashtable. If too much we could maybe
get away with only tracking exported and imported bo's in the table.
TODO: all the import/export flink/dmabuf operations are generic DRM
ioctls. Really all this functionality could be handled by a generic
drm_bo and drm_device "base class" that could be extended by omap,
exynos, etc. That would also allow more common userspace code by
avoiding artificial libdrm_omap dependencies.
