This document explains how IOThreads and the main loop are related,
especially how to write code that can run in an IOThread.  Currently
only virtio-blk-data-plane uses these techniques.  The next obvious
target is virtio-scsi; there has also been work on virtio-net.

The current version of the qcow2 specification recommends to save the backing
file name in the end of the first cluster. It follows that the backing file
name can be saved somewhere in the image, but the first cluster, which
contradicts the current QEMU implementation.

The patch makes the backing file name required to be placed after the header
extensions in the first image cluster.

In many cases, the call to event_notifier_set in aio_notify is unnecessary.
In particular, if we are executing aio_dispatch, or if aio_poll is not
blocking, we know that we will soon get to the next loop iteration (if
necessary); the thread that hosts the AioContext's event loop does not
need any nudging.

The patch includes a Promela formal model that shows that this really
works and does not need any further complication such as generation
counts.  It needs a memory barrier though.

The generation counts are not needed because any change to
ctx->dispatching after the memory barrier is okay for aio_notify.
If it changes from zero to one, it is the right thing to skip
event_notifier_set.  If it changes from one to zero, the
event_notifier_set is unnecessary but harmless.

Old code was affected by memory gaps which resulted in buffer pointers
pointing to address outside of the mapped regions.

Here we are introducing following changes:
 - new function qemu_get_ram_block_host_ptr() returns host pointer
   to the ram block, it is needed to calculate offset of specific
   region in the host memory
 - new field mmap_offset is added to the VhostUserMemoryRegion. It
   contains offset where specific region starts in the mapped memory.
   As there is stil no wider adoption of vhost-user agreement was made
   that we will not bump version number due to this change
 - other fileds in VhostUserMemoryRegion struct are not changed, as
   they are all needed for usermode app implementation
 - region data is not taken from ram_list.blocks anymore, instead we
   use region data which is alredy calculated for use in vhost-net
 - Now multiple regions can have same FD and user applicaton can call
   mmap() multiple times with the same FD but with different offset
   (user needs to take care for offset page alignment)

The conversion of events to the QAPI, resulted in the removal of the
docs/qmp/qmp-events.txt file. This was done to avoid having duplicated
information between qmp-events.txt and qapi-event.json.

However, qmp-events.txt contains examples and we're still not sure
how to proper install QAPI docs in the host. To avoid harming users,
it's better to re-add qmp-events.txt for now and deal with the
duplication later.
