exynos/fimg2d: add g2d_move
We already have g2d_copy() which implements G2D copy
operations from one buffer to another. However we can't
do a overlapping copy operation in one buffer.
Add g2d_move() which acts like the standard memmove()
and properly handles overlapping copies.

exynos: fimg2d: add g2d_set_direction
This allows setting the two direction registers, which specify how
the engine blits pixels. This can be used for overlapping blits,
which happen e.g. when 'moving' a rectangular region inside a
fixed buffer.

exynos/fimg2d: add g2d_config_event
This enables us to pass command buffers to the kernel which
trigger an event on the DRM fd upon completion.
The final goal is to enable asynchronous operation of the
G2D engine, similar to async page flips.
Passing the event userdata pointer through the G2D context
was chosen to not change the current API (e.g. by adding
a userdata argument to each public functions).

exynos/fimg2d: make g2d_add_cmd() less heavy
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().

exynos/fimg2d: add g2d_validate_xyz() functions
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.

exynos: honor the repeat mode in g2d_copy_with_scale
This is useful when the default repeat mode, which is 'repeat'
produces artifacts at the borders of the copied image.
Choose the 'pad' mode to make use of the color of the destination
image.
In my usage case the destination is the framebuffer, which is
solid filled with a background color. Scaling with 'pad' mode
would then just do the right thing and also produces nice
borders on the output.

libdrm/exynos: add test application for 2d gpu.
This patch adds library and test application for g2d gpu(fimg2d).
The fimg2d hardware is a 2D graphics accelerator(G2D) that
supports Bit Block Transfer(BitBLT).
The library includes the following primitive drawing operations:
.solid fill - This operation fills the given buffer with
the given color data.
.copy - This operation copies contents in source buffer to
destination buffer.
.copy_with_scale - This operation copies contents in source buffer
to destination buffer scaling up or down properly.
.blend - This operation blends contents in source buffer with
the ones in destination buffer.
And the above operations uses gem handle or user space address
allocated by malloc() as source or destination buffer.
And the test application includes just simple primitive drawing
tests with the above library.
And the guide to test is as the following,
"#exynos_fimg2d_test -s connector_id@crtc_id:mode"
With this above simple command, four primitive drawing operations
would be called step by step and also rendered on the output device
to the given connector and crtc id.
