8121651110 mvcdec: Integer overflow in imvcd_parse_subset_sps 
The cases where the value for log2MaxPocLsb was exceeding
'MAX_BITS_IN_POC_LSB' was not being handled correctly,
which was resulting in an integer overflow. This has been
fixed.

468e048959 mvcdec: Fixes for OOB accesses of refPicList 
[x] For certain sequences of modification_of_pic_nums_idc,
    OOB accessses of the aps_mod_dpb buffer within mvc_dpb_manager_t
    struct could occur. This case has been now detected
    and handled.
[x] Removed unused variables in 'imvcd_slice_functions.c'.

f8ae418b38 mvcdec: Bitstream buf allocation accounts for FGC SEI 
The worst case FGC SEI payload size in cojunction with the worst
case sizes of other NALU's can be significantly larger than the
default bitstream buffer size of 256000. It is now set to the sum
of 256000 and MAX_FGC_SEI_SIZE.
