Like compressed_size which indicates how many bytes are compressed, we
need encoded_size to understand how many bytes are encoded with xbzrle
during migration.
Replace the old xbzrle_counter.bytes, instead of adding a new counter,
because we don't find a usage of xbzrle_counter.bytes currently, wh
Users may need to check the xbzrle encoding rate to know if the guest
memory is xbzrle encoding-friendly, and dynamically turn off the
encoding if the encoding rate is low.

The newly added function v9fs_co_readdir_many() retrieves multiple
directory entries with a single fs driver request. It is intended to
replace uses of v9fs_co_readdir(), the latter only retrives a single
directory entry per fs driver request instead.
The reason for this planned replacement is tha
Make top half really top half and bottom half really bottom half:
Each T_readdir request handling is hopping between threads (main
I/O thread and background I/O driver threads) several times for
every individual directory entry, which sums up to huge latencies

As previously mentioned, I was investigating performance issues with 9pfs.

The previous, already existing 'basic' readdir test simply used a
