8c8381d543 Enable all-zero coeff block index for sub8x8 blk 
This commit makes zcoeff_blk cache the case where the entire block
is quantized to be zero (without applying zero-forcing) in the rate-
distortion optimization loop, and skip the forward DCT, quantization,
inverse DCT, and reconstruction process in the encode_block stage.

It now works for all the block sizes, including sub8x8 blocks.

2901bf2d00 Reducing the number of recursive calls. 
Both decode_modes_sb and decode_modes_b had conditions to immediately
return at the beginning. Eliminating these conditions here and calling
these functions only to do a real work. Also unrolling loop for
PARTITION_SPLIT.

set_scaled_offsets() to calculate x_offset_q4 and y_offset_q4.

cd94eee45f Fixing clang warning.

(aka 'enum vpx_scaling_mode_1d') to different enumeration type
'VPX_SCALING'".

156de9c3ef Correct handling of show_bit in uncompressed header. 
"keyframe" variable in the current code actually means that previous
frame is a keyframe because cm->frame_type has not been initialized
in read_uncompressed_header.

aa76cd1e49 Removing is_intra_mode() function. 
It is enough to check just block type: intra or inter. Intra block implies
intra prediction mode, and inter block implies inter mode.
