Use pointers instead of long array names
Move to use semaphores instead of conditions as paolo suggestion
Put all the state inside one struct.
Use a counter for the number of threads created. Needed during cancellation.
Add error return to thread creation
Add id field
Rename functions to multifd_save/load_setup/cleanup
Change recv parameters to a pointer to struct
Change back to a struct
Use Error * for _cleanup

Once there, be consistent and use
compress_thread_{save,load}_{setup,cleanup}.

Once there, I rename ram_migration_cleanup() to ram_save_cleanup().
Notice that this is the first pass, and I only passed XBZRLE to the
new scheme. Moved decoded_buf to inside XBZRLE struct.
As a bonus, I don't have to export xbzrle functions from ram.c.

RAM Statistics need to survive migration to make info migrate work, so we
need to store them outside of RAMState. As we already have an struct
with those fields, just used them. (MigrationStats and XBZRLECacheStats).

All functions are internal except for ram_mig_init(). Create
migration/misc.h for this kind of functions.
