hevcdec: update chroma subsample filter from neighbor to area
...
For clips with chroma format idc 444/422 and output format selected to
420, after decoding during chroma sampling conversion from 444/422 to
420, neighbor filtering is done currently. This is updated to area.

Bypass wrappers functions for memcpy and memset, calling standard
C library functions directly. This allows _FORTIFY_SOURCE to
perform compile-time safety checks.

- updated parser for 422 specific syntax elements
- updated iqitrecon module to handle 422 subtu's. Verified functionality
for intra only slices
- add support 422 i/o
- restrict combinations of output chroma format and internal chroma
format allowed. That is, for a given chroma format idc not all output
color formats are supported. The output format can now be either same
as internal color format or 420p.

Return error from cabac init if offset is greater than range
...
When the offset was greater than range, the bitstream was read
more than the valid range in leaf-level cabac parsing modules.
Error check was added to cabac init to fix this issue. Additionally
end of slice and slice error were signalled to suppress further
parsing of current slice.
