7703822731 Decoder: Fixed flag u1_top_bottom_decoded.
Fixed initialization of flag u1_top_bottom_decoded
in decoder context. This flag indicates if top
field and botton field is decoded.

0b23c81c3d Decoder: Fixed initialization of first_slice_in_pic
To handle some errors, first_slice_in_pic was being set to 2.
This is now cleaned up and first_slice_in_pic is set to 1 only once per pic.
This will ensure picture level initializations are done only once even in case
of error clips

494561291a Decoder: Moved end of pic processing to end of decode call
ih264d_end_of_pic() was called after parsing slice of a new picture.
This is now being done at the end of decode of the current picture.
decode_gaps_in_frame_num which needs frame_num of new slice is now
done after decoding frame_num in new slice.

This helps in handling errors in picaff streams with gaps in frames

1f0ab0b089 DO NOT MERGE: Decoder: Fixes an out of bound write in bitstream buffer
[this is for mnc-dev only, not any other mnc-*-dev flavors;
there is a different patch for mnc-dr-dev, nyc-* and going forward]

After emulation prevention, data is written as an int,
so at least 3 additional bytes should be available.
And since bitstream functions read 8 bytes ahead, 8 extra bytes
should be available in the bitstream buffer.

c7a1cf4e0b Ensure ih264d_start_of_pic() is not repeated in ih264d_mark_err_slice_skip()
In case of error in handling MMCO commpands/reference list creation,
ih264d_start_of_pic() was called again in ih264d_mark_err_slice_skip() resulting in
leaking a picture or an MV buffer in buffer manager.

To fix this, ensure prev_slice_err is set to 1 only if u4_pic_buf_got is zero, before
calling ih264d_mark_err_slice_skip() at the end of picture decode.
This will ensure ih264d_start_of_pic() is not repeated

85a43d2fcf Fix string handling for generating version strings
Don't do concatenation with strncat; the length parameter in strncat
is only for how many chars to append at most, not for the full output
buffer size. To safely use strncat, one would have to do
strncat(buf, str, sizeof(buf) - strlen(buf)).

By using snprintf, we guarantee that the buffer is null terminated, and
we don't need to use strnlen at all.

(If compatibility with older MSVC versions that lack snprintf, one
can use _snprintf instead and manually add the null termination.)
