qemu-file: temporarily expose qemu_file_set_error and qemu_fflush

Right now, migration cannot entirely rely on QEMUFile's automatic
drop of I/O after an error, because it does its "real" I/O outside
the put_buffer callback. To fix this until buffering is gone, expose...

migration: simplify error handling

Always use qemu_file_get_error to detect errors, since that is how
QEMUFile itself drops I/O after an error occurs. There is no need
to propagate and check return values all the time.

Also remove the "complete" member, since we know that it is set (via...

migration: cleanup migration (including thread) in the iothread

Perform final cleanup in a bottom half, and add joining the thread to
the series of cleanup actions.

migrate_fd_error remains for connection error, but it doesn't need
to cleanup anything anymore....

block-migration: add lock

Some state is shared between the block migration code and its AIO
callbacks. Once block migration will run outside the iothread,
the block migration code and the AIO callbacks will be able to
run concurrently. Protect the critical sections with a separate...

migration: reorder SaveVMHandlers members

This groups together the callbacks that later will have similar
locking rules.

migration: run pending/iterate callbacks out of big lock

This makes it possible to do blocking writes directly to the socket,
with no buffer in the middle. For RAM, only the migration_bitmap_sync()
call needs the iothread lock. For block migration, it is needed by...

tcg: Don't make exitreq flag a local temporary

The value is not actually live across basic blocks, so there's no
need for the local property. This eliminates storing the temporary
to its home location at the branch.
