Fixed the bug that prevents torrent download from finishing.
The bug doesn't reveal for all torrents. The torrents affected
this bug satisfies ((N+7)/8)%4 == 0 and N%32 != 0 where N is the
number of pieces.

byte.

BitfieldMan::getMissingIndexes family functions now takes
unsigned char* bitfield instead of stl container for efficiency.
PieceSelector::select now takes this
bitfield. RarestPieceSelector::select now also performs
efficiently for this change. bitfield namespace is introduced
and it has several helper functions to handle basic bitfield
operations such as test, count set bits, etc.
