icount: prepare the code for future races in calling qemu_clock_warp
Computing the deadline of all vm_clocks is somewhat expensive and calls
out to qemu-timer.c; two reasons not to do it in the seqlock's write-side
critical section. This however opens the door for races in setting and
reading vm_clock_warp_start.
To plug them, we need to cover the case where a new deadline slips in
between the call to qemu_clock_deadline_ns_all and the actual modification
of the icount_warp_timer. Restrict changes to vm_clock_warp_start and
the icount_warp_timer's expiration time, to only move them back (which
would simply cause an early wakeup).
If a vm_clock timer is cancelled while CPUs are idle, this might cause the
icount_warp_timer to fire unnecessarily. This is not a problem, after it
fires the timer becomes inactive and the next call to timer_mod_anticipate
will be precise.
In addition to this, we must deactivate the icount_warp_timer _before_
checking whether CPUs are idle. This way, if the "last" CPU becomes idle
during the call to timer_del we will still set up the icount_warp_timer.

spice: fix multihead support
This patch fixes spice display initialization to handle
multihead properly.
spice-core now keeps track of which QemuConsole has a spice
display channel attached to it and which has not. It also
manages display channel ids.
spice-display looks at all QemuConsoles and will pick up any
graphic console not yet bound to a spice channel (which in practice
are all non-qxl graphic devices).
Result is that
(a) you'll get a spice client window for each graphical device
now (first only without this patch), and
(b) mixing qxl and non-qxl vga cards works properly.
Fix VNC SASL authentication when using a QXL device
ui/vnc.c:vnc_display_open() and spice-server/server/reds.c:do_spice_init()
are both calling sasl_server_init(). If spice_server_set_sasl_appname()
hasn't been called, spice-server will call it with "spice" as an appname,
causing cyrus-sasl to try to use a /etc/sasl2/spice.conf config file rather
than the /etc/sasl2/qemu.conf file that QEMU uses.
When using -spice sasl on the command line, QEMU properly calls
spice_server_set_sasl_appname() to set the SASL appname as "qemu",
but when using a QXL device without using SPICE, spice_server_init()
is called from qemu_spice_add_interface() without setting the appname
to "qemu", which then causes the VNC code to try to use spice.conf
instead of qemu.conf.

Once we form a combined qemu_st_i32 opcode, we won't be able to
have separate constraints based on size. This one is fairly easy
to work around, since eax is available as a scratch register.
When storing variable data, this tends to merely exchange one mov
for another. E.g.
Where we do have a regression is when storing constant data, in which
we may load the constant into edi, when only ecx/ebx ought to be used.
The proper way to recover this regression is to allow constants as
arguments to qemu_st_i32, so that we never load the constant data into
a register at all, must less the wrong register. TBD.

qdev-monitor: Group "device_add help" and "info qdm" by category
Output is a long, unsorted list. Not very helpful. Print one list
per device category instead, with a header line identifying the
category, plus a list of uncategorized devices. Print each list in
case-insenitive alphabetical order.
Devices with multiple categories are listed multiple times.

The commit claims to sort the output of "-device help" "by
functionality rather than alphabetical". Issues:
* The output was unsorted before, not alphabetically sorted.
Misleading, but harmless enough.
* The commit doesn't just sort the output of "-device help" as it
claims, it adds categories to each line of "-device help", and it
prints devices once per category. In particular, devices without a
category aren't shown anymore. Maybe such devices should not exist,
but they do. Regression.
* Categories are also added to the output of "info qdm". Silent
change, not nice. Output remains unsorted, unlike "-device help".
I'm going to reimplement the feature we actually want, without the
warts. Reverting the flawed commit first should make it easier to
review. However, I can't revert it completely, since DeviceClass
member categories has been put to use. So leave that part in.

Use qemu-project.org domain name
qemu.org is held by a third-party and no core community contributor has
access to the DNS configuration. This leaves the website exposed to
outages due to DNS issues or IP address changes. For example, if the
web server IP address needs to change we cannot guarantee qemu.org will
point to it!
The newer qemu-project.org domain name is owned by Anthony Liguori
<anthony@codemonkey.ws>. You can confirm this by querying the whois
information. Also note that the #qemu IRC channel topic already
references qemu-project.org.
Short of having a dedicated legal entity to hold the domain name on
behalf of the community, qemu-project.org seems like the safest bet.
Let's replace references to qemu.org with qemu-project.org.
Note that git-submodule(1) does not detect URL changes. The following
commands clear out and re-initialize all submodules to ensure you are
using the latest URLs:
$ git submodule deinit . # you'll be warned if you have local changes
$ rm -rf .git/modules # also clear cached .git/ directories
$ git submodule update --init

blockdev: Remove IF_* check for read-only blockdev_init
IF_NONE allows read-only, which makes forbidding it in this place
for other types pretty much pointless.
Instead, make sure that all devices for which the check would have
errored out check in their init function that they don't get a read-only
BlockDriverState. This catches even cases where IF_NONE and -device is
used.

blockdev: Pass QDict to blockdev_init()
Working on a QDict instead of a QemuOpts that accepts anything is more
in line with bdrv_open(). A QDict is what qmp_blockdev_add() already has
anyway, so this saves additional conversions. And last, but not least,
it allows later patches to easily extract legacy options into a
separate, typed QemuOpts for drive_init() (the untyped QemuOpts that
drive_init already has doesn't allow access to numbers, only strings,
and is therefore useless without conversion).
