7dbacdf765 Added code to handle cases with qp less than 10
When qp goes less than 10, all I16x16 mode evaluations
are disabled and I4x4 evaluations are enabled irrespective
of preset. This will ensure that the residual will not
exceed the supported range of entropy

Minimum Qp cannot be set less than 4 now. When QP goes lesser,
the residual may exceed the supported range even with I4x4 enabled.

d3e18f0c88 Reduced memory requirements.
Buffer allocation is based on minimum level required for the
input resolution rather than the input max level.

Number of maximum context sets can be set to 1 to reduce
memory usage.

Added a macro ENC_MIN_PU_SIZE for minimum size of
inter prediction unit supported by encoder.

Changed the maximum constraint on number of MBs for NMB
processing to width in Mbs.

4f5ceca078 Always copy data to a local buffer if padding is needed
If horizontal padding is needed, copy the data to avoid having to try
to write into the input buffer.

If vertical padding is needed, we could get away with only copying
the last MB row (as previously was done), but then one extra row of
pixels are needed for intra pred. Thus always copy all of the picture,
for simplicity, if padding is needed.

cb6a43532c Set the luma/chroma strides depending on source buffer
If the data is read directly from the input buffer, set the stride
values to those of the input buffer. If the data is copied, set the
stride to the value of the local buffer instead.

This fixes handling of cases where the input buffer stride is
(significantly) larger than the maxwidth of the video.

This also effectively makes the parameter
ive_ctl_set_dimensions_ip_t.u4_strd useless - nothing needs to
know the stride until you actually encode a frame, and at that point,
we can either use the stride of the input buffer, or of the local
pu1_y_csc_buf_base where the copied content is stored.

9113f5615c Use a separate field for the chroma stride
When both luma and chroma are copied to the local buffer (either
due to yuv format conversion, or due to padding), they have got
the same stride, but if chroma is copied while luma is used directly
from the input buffer, they might have different strides.

Therefore add a separate field for chroma stride.

This commit only adds the field, while it still has got the same
value as before.

1ff75b8cc0 Only initialize u4_deblk_prev_row if it will be used
This avoids reads out of bounds when encoding videos with a height
of one single macroblock.
