Both drmGetDevice() and drmGetDevices() currently print a warning when
they encounter an unknown (non-PCI) subsystem type for a device node,
but they still proceed to assume that the drmDevicePtr was initialized
and try to add it to the local device array. Add a 'continue' to the
error case handling to bypass the rest of the processing for devices we
can't handle.

If the opendir() call in drmGetDevices() returns failure, we jump to an
error label that calls closedir() and then returns. However this means
that we're calling closedir(NULL) which may not be safe on all
implementations. We are also leaking the local_devices array that was
allocated before the opendir() call.
Fix both of these issues by jumping to an earlier error label (to free
local_devices) and guarding the closedir() call with a NULL test.

The function currently checks for each added command
if an overflow of the corresponding command buffers
occurs, but none of the callers ever checks the
return value.
Since all callers are now converted to use
g2d_check_space() simplify the function.
(1) The overflow checks become asserts, so they're only
active for debug builds. This is fine since
g2d_add_cmd() is not part of the public API.
(2) Switch the return value to void.
(3) Explicitly state that the caller has to check
buffer space before calling g2d_add_cmd().

The G2D headers define a number of modes through enums
(like e.g. color, select, repeat, etc.).
This introduces g2d_validate_select_mode() and
g2d_validate_blending_op() which validate a
select mode or blending operation respectively.
Use this together with g2d_check_space() in
g2d_{blend,scale_and_blend}().
For this we move parameter validation to the top and
also validate the select mode of the source image and
the requested blending operation before starting
command submission.

This is going to be used to check if the command buffers have
enough space left prior to actual submission of the commands.
Use this in g2d_{solid_fill,copy,copy_with_scale}().
For this the parameter validation before buffer space

Also don't reset the G2D context in this situation since
the buffers are not partially submitted anymore.
The repeat mode in g2d_copy_with_scale() is checked first
to make computation of space easier.

This allows us to ease the error handling and simplify the

such so that it frees the relevant hunks, rather than leaving that to
the caller.
