omap: add refcnting and handle tracking

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.

intel: Change context create failure message to from fprintf to DBG().

Since there is no getparam for hardware context support, Mesa always
tries to obtain a context by calling drm_intel_gem_context_create and
NULL-checking the result.  On an older kernel without context support,
this caused libdrm to print an unwanted message to stderr:

DRM_IOCTL_I915_GEM_CONTEXT_CREATE failed: Invalid argument

In fact, this caused every Piglit test to fail with a "warn" status due
to the unrecognized error message.

Change the message to use DBG() rather than fprintf(), so people can
still get the debug message, but it won't spam normally.
