History
Sheng Yang 26418649ee target/user: Introduce data_bitmap, replace data_length/data_head/data_tail 
The data_bitmap was introduced to support asynchornization accessing of
data area.

We divide mailbox data area into blocks, and use data_bitmap to track the
usage of data area. All the new command's data would start with a new block,
and may left unusable space after it end. But it's easy to track using
data_bitmap.

Now we can allocate data area for asynchronization accessing from userspace,
since we can track the allocation using data_bitmap. The userspace part would
be the same as Maxim's previous asynchronized implementation.
