hw/i386/Makefile.obj: use $(PYTHON) to run .py scripts consistently
$(PYTHON) is a Make variable which is set by configure.

qga: Fix shutdown command of guest agent to work with SysV
For now guest agent uses following command to shutdown system:
shutdown -P +0 "blabla"
but this syntax works only with shutdown command from systemd or upstart,
because SysV shutdown requires -h switch.
Following patch changes the command so it works with systemd, upstart and SysV
With upstart/systemd qga use one of thee commands, depending on 'mode' parameter:
shutdown -P +0 "..."
shutdown -H +0 "..."
shutdown -r +0 "..."
SysV equivalents for these are:
shutdown -h -P +0 "..."
shutdown -h -H +0 "..."
shutdown -h -r +0 "..."
and these retain their meaning with upstart/systemd.
According to FreeBSD manpages, shutdown does not accept -P and -H options. Commands should be:
shutdown -p +0 "..."
shutdown -h +0 "..."
shutdown -r +0 "..."
shutdown in Solaris does not accept any of -hHpPr and does not accept time in "+0" format

.travis.yml: basic compile and check recipes
This adds a build matrix definition for travis-ci.org continuous
integration service. It is usable on any public repository hosted on
GitHub. Once you have created an account signed into Travis you can
enable it on selected projects via travis-ci.org/profile. Alternatively
you can configure the service hooks on GitHub via the repository
Settings tab,then Service Hooks and selecting Travis.
Once setup Travis will automatically test every push as well as any pull
requests submitted to that repository.
The build matrix is currently split by target architecture (see TARGETS
environment variable) because a full build of QEMU can take some time.
This way you get quick feedback for any obvious errors. The additional
environment variables exist to allow additional builds to tweak the
environment. These are:
EXTRA_CONFIG - extra terms passed to configure
EXTRA_PKGS - extra dev packages to install
TEST_CMD - default "make check", can be overridden
I've confined the additional stuff to x86/x86_64 for convenience.
As Travis supports clang the main builds are done twice (once for gcc
and once for clang). However clang is disabled for the debug/trace
builds for the purposes of brevity.
Other wrinkles:
* The lttng user-space tracing back-end is disabled
(it is currently horribly broken)
* The ftrace back-end doesn't run "make check"
(it requires a mounted debugfs to work)
* There are two debug enabled build (with and without TCG interpreter)

qemu-char: add missing characters used in keymaps
This patch adds all missing characters used in regional keymap
files which already exist in QEMU. I checked for the missing
characters by going through all of the keymaps and matching that
with records in vnc_keysym.h. If the key wasn't found I looked
it up in libxkbcommon library [1]. If I understood it correctly
this is also the same place where most of the keymaps were
exported from according to the comment on the first line in those
files. I was able to find all symbols except "quotebl" used
in Netherland keymap.
I tested this update with Czech keyboard by myself. I also asked
Matej Serc to test Slovenian keyboard layout - he reported problems
with it few days ago on this mailing list. Both layouts seems
to work fine. I wasn't able to test the remaining layouts but
since this change doesn't modify any existing symbols, just adds
new ones, I don't expect any sideeffects.

timers: fix stop/cont with -icount
Stop/cont commands are broken with -icount due to a deadlock. The
real problem is that the computation of timers_state.cpu_ticks_offset
makes no sense with -icount enabled: we set it to an icount clock value
in cpu_disable_ticks, and subtract a TSC (or similar, whatever
cpu_get_real_ticks happens to return) value in cpu_enable_ticks.
The fix is simple. timers_state.cpu_ticks_offset is only used
together with cpu_get_real_ticks, so we can use cpu_get_real_ticks
in cpu_disable_ticks. There is no need to update cpu_ticks_prev
at the time cpu_disable_ticks is called; instead, we can do it
the next time cpu_get_ticks is called.
The change to cpu_disable_ticks is the important part of the patch.
The rest modifies the code to always check timers_state.cpu_ticks_prev,
even when the ticks are not advancing (i.e. the VM is stopped). It also
makes a similar change to cpu_get_clock_locked, so that the code remains
similar for cpu_get_ticks and cpu_get_clock_locked.

The device will be freed when its QObject refcount reaches zero. It is
usual for the parent (bus) to hold the final reference but there are

name.

ossaudio: do not enable by default

pci, pc, pvpanic bug fixes
This fixes strange pvpanic behaviour: you had to
pause to let VM continue (and potentially reboot on panic
if enabled).
This also fixes two bugs reported by Andreas.
One is a long-standing bug exposed by recent pci changes,
the other affects old piix machine types and was caused
by recent acpi changes.

vl: allow "cont" from panicked state
After reporting the GUEST_PANICKED monitor event, QEMU stops the VM.
The reason for this is that events are edge-triggered, and can be lost if
management dies at the wrong time. Stopping a panicked VM lets management
know of a panic even if it has crashed; management can learn about the
panic when it restarts and queries running QEMU processes. The downside
is of course that the VM will be paused while management is not running,
but that is acceptable if it only happens with explicit "-device pvpanic".
Upon learning of a panic, management (if configured to do so) can pick a
variety of behaviors: leave the VM paused, reset it, destroy it. In
addition to all of these behaviors, it is possible to dump the VM core
from the host.
However, right now, the panicked state is irreversible, and can only be
exited by resetting the machine. This means that any policy decision
is entirely in the hands of the host. In particular there is no way to
use the "reboot on panic" option together with pvpanic.
This patch makes the panicked state reversible (and removes various
workarounds that were there because of the state being irreversible).
With this change, management has a wider set of possible policies: it
can just log the crash and leave policy to the guest, it can leave the
VM paused. In particular, the "log the crash and continue" is implemented
simply by sending a "cont" as soon as management learns about the panic.
Management could also implement the "irreversible paused state" itself.
And again, all such actions can be coupled with dumping the VM core.
Unfortunately we cannot change the behavior of 1.6.0. Thus, even if
it uses "-device pvpanic", management should check for "cont" failures.
If "cont" fails, management can then log that the VM remained paused
and urge the administrator to update QEMU.

The page table logic in exec.c assumes
that memory addresses are at most TARGET_PHYS_ADDR_SPACE_BITS.
But pci addresses are full 64 bit so if we try to render them ignoring
the extra bits, we get strange effects with sections overlapping each
other.
To fix, simply limit the system memory size to
1 << TARGET_PHYS_ADDR_SPACE_BITS,
pci addresses will be rendered within that.

qxl: replace pipe signaling with bottom half
qxl creates a pipe, then writes something to it to wake up the iothread
from the spice server thread to raise an irq. These days qemu bottom
halves can be scheduled from threads and signals, so there is no reason
to do this any more. Time to clean it up.
