Level conformance is standadized in vp9.
If a specific target level is set, the vp9 encoder is required to
produce conformant bitstream with limit on frame size, rate,
min alt-ref distance, etc.
This change makes the SimpleEncode environment take the target level
as an input.
To make existing tests pass, we set the level to 0.

Two pass rc parameters are only initialized in the second pass
in vp9 normal two pass encoding.
However, the simple_encode API queries the keyframe group, arf group,
and number of coding frames without going throught the two pass
route.
Since recent libvpx rc changes, parameters in the TWO_PASS
struct have a great influence on the determination of the above
information.
We therefore need to properly init two pass rc parameters in
the simple_encode related environment.

Recently, some function signatures have been changed.
This change fixes compilation error if --enable-rate-ctrl is used.

Tpl stats is computed at the beginning of encoding the altref
frame. We aggregate tpl stats of all blocks for every frame of
the current group of picture.
After the altref frame is encoded, the tpl stats is passed through
the encode frame result to external environment.

1) Use kRefFrameTypeNone in the unit test
2) Reset mv_info in fp_motion_vector_info_init
3) Call fp_motion_vector_info_init() in first_pass_encode()
4) Set mv_info for intra frame.
5) Set mv_info with zero mv as default for inter frame
6) Remove duplicated fp_motion_vector_info in encode_frame_info

Store motion vectors for each 16x16 block found in the first pass
motion search.
Provide an api "ObserveFirstPassMotionVector()" in SimpleEncode
class, similar to "ObserveFirstPassStats()".

Let SetExternalGroupOfPicturesMap() modify the gop_map_ to satisfy
the following constraints.
1) Each key frame position should be at the start of a gop.
2) The last gop should not use an alt ref.
Add unit test for SetExternalGroupOfPicturesMap()
Change-Id: Iee9bd238ad0fc5c2ccbf2fbd065a280c854cd718
Rename external_arf_indexes by gop_map
Use kGopMapFlagStart to indicate the start of a gop in the gop_map.
Use kGopMapFlagUseAltRef to indicate whether to use altref in the
gop_map.

Send GOP_COMMAND to vp9 for setting gop decisions on the fly.
GOP_COMMAND has three members.
use: use this command to set gop or use vp9's gop decision.
show_frame_count: number of show frames in this gop.
use_alt_ref: use alt ref frame or not.
Move the logic of processing external_arf_indexes_ from
get_gop_coding_frame_num() to GetGopCommand() and
GetCodingFrameNumFromGopMap().

Fix several bugs to make the test pass.
1) Move update_frame_indexes() out of show_frame check.
2) Init coding_indexes[i] to -1 when key frame appears
3) Fix a bug in PostUpdateRefFrameInfo()

It's necessary to get data pointer from a vector sometimes.
This function will guarantee that the data pointer is nullptr
if the vector is empty.

RefFrameInfo contains the coding_indexes and valid_list of

Add a test to ensure that encoding with the external arfs gets the
same result as long as the arfs are the same as the vp9 baseline.

Add coding_index to EncodeFrameInfo
Add start_coding_index to GroupOfPicture
Add frame_coding_index_ to SimpleEncode
The definition of coding index is as follows.
Each show or no show frame is assigned with a coding index based
on its coding order (starting from zero) in the coding process of
the entire video. The coding index for each frame is unique.

Allocate partition information for the frame, and update it
when a superblock (64x64) is encoded.
The unit size of the smallest block is 4x4.
For each 4x4 block, store the current positition (row, column),
the start positition (row_start, column_start) of the partition,
and the block width and height of the partition.
