qcow2: Split do_perform_cow() into _read(), _encrypt() and _write()
This patch splits do_perform_cow() into three separate functions to
read, encrypt and write the COW regions.
perform_cow() can now read both regions first, then encrypt them and
finally write them to disk. The memory allocation is also done in
this function now, using one single buffer large enough to hold both
regions.

qcow2: Use unsigned int for both members of Qcow2COWRegion
Qcow2COWRegion has two attributes:
- The offset of the COW region from the start of the first cluster
touched by the I/O request. Since it's always going to be positive
and the maximum request size is at most INT_MAX, we can use a
regular unsigned int to store this offset.
- The size of the COW region in bytes. This is guaranteed to be >= 0,
so we should use an unsigned type instead.
In x86_64 this reduces the size of Qcow2COWRegion from 16 to 8 bytes.
It will also help keep some assertions simpler now that we know that
there are no negative numbers.
The prototype of do_perform_cow() is also updated to reflect these
changes.

We are using the return value of qcow2_encrypt_sectors() to detect

local Error variable and pass NULL instead.
Alternatively we could try to figure out a way to pass the original

invasive, so let's keep the current approach.

migration: use bdrv_drain_all_begin/end() instead bdrv_drain_all()
blk/bdrv_drain_all() only takes effect for a single instant and then
resumes block jobs, guest devices, and other external clients like the
NBD server. This can be handy when performing a synchronous drain
before terminating the program, for example.
Monitor commands usually need to quiesce I/O across an entire code
region so blk/bdrv_drain_all() is not suitable. They must use
bdrv_drain_all_begin/end() to mark the region. This prevents new I/O
requests from slipping in or worse - block jobs completing and modifying
the graph.
I audited other blk/bdrv_drain_all() callers but did not find anything
that needs a similar fix. This patch fixes the savevm/loadvm commands.
Although I haven't encountered a read world issue this makes the code
safer.

migration: avoid recursive AioContext locking in save_vmstate()
AioContext was designed to allow nested acquire/release calls. It uses
a recursive mutex so callers don't need to worry about nesting...or so
we thought.
BDRV_POLL_WHILE() is used to wait for block I/O requests. It releases
the AioContext temporarily around aio_poll(). This gives IOThreads a
chance to acquire the AioContext to process I/O completions.
It turns out that recursive locking and BDRV_POLL_WHILE() don't mix.
BDRV_POLL_WHILE() only releases the AioContext once, so the IOThread
will not be able to acquire the AioContext if it was acquired
multiple times.
Instead of trying to release AioContext n times in BDRV_POLL_WHILE(),
this patch simply avoids nested locking in save_vmstate(). It's the
simplest fix and we should step back to consider the big picture with
all the recent changes to block layer threading.
This patch is the final fix to solve 'savevm' hanging with -object
iothread.

docker: update qemu:debian base following stretch release
Debian has now released Stretch as its new stable. As we track
debian:stable-slim this has a few consequences. For one thing we can
now drop the emdebian hacks as cross compilers are part of the
official repositories now. However we do loose the ability to build
against powerpc (not ppc64) since that is no longer a release
architecture.

usb-host: support devices with sparse/non-sequential USB interfaces
Some USB devices have sparse interface numbering which is not able to be
passthroughed.
For example, the Sierra Wireless MC7455/MC7430:
# lsusb -D /dev/bus/usb/003/003 | egrep '1199|9071|bNumInterfaces|bInterfaceNumber'
Device: ID 1199:9071 Sierra Wireless, Inc.
idVendor 0x1199 Sierra Wireless, Inc.
idProduct 0x9071
bNumInterfaces 5
bInterfaceNumber 0
bInterfaceNumber 2
bInterfaceNumber 3
bInterfaceNumber 8
bInterfaceNumber 10
In this case, the interface numbers are 0, 2, 3, 8, 10 and not the
0, 1, 2, 3, 4 that QEMU tries to claim.
This change allows sparse USB interface numbering.
Instead of only claiming the interfaces in the range reported by the USB
device through bNumInterfaces, QEMU attempts to claim all possible
interfaces.
v2 to fix broken v1 patch formatting.
v3 to fix indentation.
