H A Dhbitmap.hdiff 8258888e222ff03bf791d81a0001cdc40b878de4 Thu Oct 13 16:58:27 CDT 2016 Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com> hbitmap: serialization

Functions to serialize / deserialize(restore) HBitmap. HBitmap should be
saved to linear sequence of bits independently of endianness and bitmap
array element (unsigned long) size. Therefore Little Endian is chosen.

These functions are appropriate for dirty bitmap migration, restoring
the bitmap in several steps is available. To save performance, every
step writes only the last level of the bitmap. All other levels are
restored by hbitmap_deserialize_finish() as a last step of restoring.
So, HBitmap is inconsistent while restoring.
