If all the slices in the current pic were invalid, then
the decoder would not have received a valid picture buffer
in the current call. In such cases there is no need to conceal or
deblock the picture.

The output buffer size given by the application, needs to be checked
in every process call. This is required in the case of resolution
change.

If resolution changes within a decode call,due to multiple
sps, the decoder hangs as the the application will
give the same data again in the next decode call. This
results in a hang. Fixed this by flaging an error,
when sps/resoultion changes within a process call.

Reference list needs to be initialized for every P/B
slice, to ensure colocated picture always points to a
valid picture buffer, even in the case of error.

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

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

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

[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.

At the end of picture processing, if the current pic is partially
decoded, number of MBs to be processed was wrongly calculated for
interlaced cases.
