This reverts commit f76370c671.
Reason: This breaks interlaced clips which are sent one field at a time
C2 plugin for avc decoder is now updated to appropriately handle both
types of interlaced content, i.e. sent as one field per one input buffer
and sent as two fields per one input

When removing common nodes from short term list if it present in long
term reference list, number of long term buffers was wrongly
incremented. Only decrement of short term buffer count is needed in
such a case.

When decoder is expecting to decode a field, ensure current slice
being decoded is a field and frame number matches with previous slice's
frame number.

Currently frame_decoded was set to 1 after first field was decoded
This field in output wasn't used so far, hence no issue was seen till
now.

If lt_list and st_list point to same node then delete it from st.
If there is error while adding a node in bottom field of lt_list (top is
already added) then this node will be pointed by st_list also. So we need
to remove it from st_list

Increased allocation to include reference list1 also by

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
