Add the bdrv_aio_copy_backing() function to the BlockDriver interface.
This function copies unallocated sectors from the backing file and can
be used to implement image streaming.

Overview
This patch series adds image streaming support for QED image files. Other
image formats can also be supported in the future.
Image streaming populates the file in the background while the guest is
running. This makes it possible to start the guest before its image file has
Copy-on-read requests will share the allocating write code path. This
requires making qed_aio_write_alloc() reusable outside of a write
request. This patch ensures that iovec setup is performed in a common
place before qed_aio_write_alloc() is called.

The block layer emulates synchronous bdrv_read()/bdrv_write() for
drivers that only provide the asynchronous interfaces. The emulation
issues an asynchronous request inside a new async context and waits
for that request to complete. If currently outstanding requests
complete during this time,
It is useful to understand why an I/O request was failed. Add trace
events for the error paths in bdrv_aio_readv() and bdrv_aio_writev().

From: Anthony Liguori aligu...@us.ibm.com
For leaf images with copy-on-read semantics, the stream commands allow the user
to populate local blocks by manually streaming them from the backing image.
Once all blocks have been streamed, the dependency on the original backing
image can be removed.
Copy-on-read requests are a form of allocating write and will need to be
queued like other allocating writes. This patch extracts the request
queuing code for allocating writes so that it can be reused for
copy-on-read in a later patch.

The checkpatch.pl coding style checker complains that there should be a

qemu-config.c in the future by complying with the coding style here.
A follow-up patch adds new options to qemu-config.c and therefore
benefits from this fix.
There is no convenient way to create a QError object without reporting
it immediately. This patch adds the qerror_from_args() function to make
it easy to create an error in qerror_report() style but without

This patch adds the -drive copy-on-read=on|off command-line option:

same backing file sectors repeatedly and is useful when the
Per-request attributes like read/write are currently implemented as bool

This is the actual guest daemon, it listens for requests over a

to dispatch routines, and writes the results back to the channel in
a manner similar to QMP.
