Improve bitmask construction

(1). At decoder, store is_coding_block_border correctly if
block size > 64x64.
(2). Correctly use unit64_t for skip and is_coding_block_border at
bitmask construction to avoid int overflow.
(3). Fix a bug when storing bitmask at decoder, block size error.

if decoder stores bitmask at max depth - 1, do not call store bitmask
at max depth.
