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

ef27433ca8 Decoder: Fix in checking first_mb_in_slice 
Also, increment slice header only if previous slice had atleast one MB
This is to ensure there is no out of bound read for streams with 1 MB, and
due to error 2 slices were being accessed.

This fixes building with compilers that are strict about the pre-C99
rule about having all variable declarations before statements.
