Earlier if an MB was coded as intra in the previous frame,
corresponding MB in the current frame will not be coded as intra
even though it was supposed to be intra according to adaptive intra refresh.
Now the MB will honour adaptive intra refresh irrespective of its type
in previous frame.

pu2_intr_rfrsh_map was initialized with a wrong pointer which was
resulting in an out of bound write.
This was resulting in inconsistent output between runs when AIR was

BIPRED ME was discarding the halfpel motion vector components

The stored i4_mb_distortion that was used as i4_max_sad previously
might come from a different coding mode - even if
pf_ime_compute_sad_16x16 returns early when i4_mb_distortion is
larger than ps_mb_ctxt_bi->i4_mb_distortion, the calculated i4_mb_cost
can still end up smaller than ps_mb_ctxt_bi->i4_mb_cost.
Therefore, set i4_max_sad to INT_MAX to avoid the early exit in
pf_ime_compute_sad_16x16 here, since it can't be used reliably (and
returning early can end up choosing a suboptimal mode).
This makes sure that the encoded output is identical when the SIMD
optimized routines are disabled, when using B-frames.

When encoding in header mode, the s_inp_buf struct that was written
to ps_video_encode_op->s_ive_op.s_inp_buf was completely uninitialized.
In ih264e_input_queue_update, make sure to initialize u4_is_last
when skipping frames.

Since 6cb6772805, the actual level used is
MAX(u4_max_level, ih264e_get_min_level()), which means that it isn't
a fatal error to set u4_max_level to a too low level (if the caller
doesn't know or care). Despite this, the actual value set by the caller
was still used for initializing the RC.
This allows the caller to not have to set u4_max_level (currently
every caller has to duplicate a table or code snippet for determining
the right level for each resolution). The caller still can set it
to a higher value if he wants to explicitly use a higher level than
what is necessary.
This makes sure that the output is identical even if u4_max_level is
set too low.

This fixes building with compilers that are strict about the pre-C99

(The previous version of this commit was originally made before
the commit adding support for main profile, which added a bunch
more similar issues.)

If ENTROPY_TRACE is defined, the value parameter gets evaluated

If the current slice isn't BSLICE, u1_weighted_bipred_idc is
uninitialized, which valgrind can complain about (mostly in uninitialized

jumps based on uninitialized data.

Now once that the encoder supports the main profile, allow it to
be set in the IVE_CMD_CTL_SET_PROFILE_PARAMS request.
The actual profile value set here is ignored in practice, but
at least allow setting it to main.

Added an error check on the size allocated for output buffer.

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.

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.

Setting I frame interval to 1 caused encoder to go into
infinite loop. Fixed that by stopping RC update.
Forcing of I and IDR frame did not cause the frames at expected time
due to delayed encoding. This is fixed now.

This field isn't used at the moment at all. The public field

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.

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.

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.

Some versions of the clang built-in assembler interprets /* as a start
of a multi-line comment, even within lines starting with a @. Therefore,
make sure to terminate these properly.
This fixes warnings about /* within a block comment when building

fixes issues where part of the assembly source was effectively
commented out, when building with this assembler.

Most of them was benign and didn't risk any data race; they
were used for write-only memory during init.
The array as_itt_memtab in ih264e_get_rate_control_mem_tab
could however cause a real data race, if multiple threads
try to initialize an encoder at the same time, since it
used as temporary storage when mapping between different
structs.
