README: fill out some useful quickstart information
The README file is usually the first thing consulted when a user
or developer obtains a copy of the QEMU source. The current QEMU
README is lacking immediately useful information and so not very
friendly for first time encounters. It either redirects users to
qemu-doc.html (which does not exist until they've actually
compiled QEMU), or the website (which assumes the user has
convenient internet access at time of reading).
This fills out the README file as simple quick-start guide on
the topics of building source, submitting patches, licensing
and how to contact the QEMU community. It does not intend to be
comprehensive, instead referring people to an appropriate web
page to obtain more detailed information. The intent is to give
users quick guidance to get them going in the right direction.

qemu-sockets: fix conversion of ipv4/ipv6 JSON to QemuOpts
The QemuOpts-based code treats "option not set" and "option set
to false" the same way for the ipv4 and ipv6 options, because it
is meant to handle only the ",ipv4" and ",ipv6" substrings in
hand-crafted option parsers.
When converting InetSocketAddress to QemuOpts, however, it is
necessary to handle all three cases (not set, set to true, set
to false). Currently we are not handling all cases correctly.
The rules are:
* if none or both options are absent, leave things as is
* if the single present option is Y, the other should be N.
This can be implemented by leaving things as is, or by setting
the other option to N as done in this patch.
* if the single present option is N, the other should be Y.
This is handled by the "else if" branch of this patch.
This ensures that the ipv4 option has an effect on Windows,
where creating the socket with PF_UNSPEC makes an ipv6
socket. With this patch, ",ipv4" will result in a PF_INET
socket instead.

exec.c: Collect AddressSpace related fields into a CPUAddressSpace struct
Gather up all the fields currently in CPUState which deal with the CPU's
AddressSpace into a separate CPUAddressSpace struct. This paves the way
for allowing the CPU to know about more than one AddressSpace.
The rearrangement also allows us to make the MemoryListener a directly
embedded object in the CPUAddressSpace (it could not be embedded in
CPUState because 'struct MemoryListener' isn't defined for the user-only
builds). This allows us to resolve the FIXME in tcg_commit() by going
directly from the MemoryListener to the CPUAddressSpace.
This patch extracts the actual update of the cached dispatch pointer
from cpu_reload_memory_map() (which is renamed accordingly to
cpu_reloading_memory_map() as it is only responsible for breaking
cpu-exec.c's RCU critical section now). This lets us keep the definition

netfilter: add a netbuffer filter
This filter is to buffer/release packets. Can be used when using
MicroCheckpointing or other Remus like VM FT solutions.
You can also use it to crudely simulate network delay. Doesn't
actually delay individual packets, but batches them together, which is
a delay of sorts.
Usage:
-netdev tap,id=bn0
-object filter-buffer,id=f0,netdev=bn0,queue=rx,interval=1000
NOTE:
Interval is in microseconds, it can't be omitted currently, and can't be 0.

Revert "qdev: Use qdev_get_device_class() for -device <type>,help"
This reverts commit
31bed5509dfcbdfc293154ce81086a4dbd7a80b6.
The reverted commit changed qdev_device_help() to reject abstract
devices and devices that have cannot_instantiate_with_device_add_yet
set, to fix crash bugs like -device x86_64-cpu,help.
Rejecting abstract devices makes sense: they're purely internal, and
the implementation of the help feature can't cope with them.
Rejecting non-pluggable devices makes less sense: even though you
can't use them with -device, the help may still be useful elsewhere,
for instance with -global. This is a regression: -device FOO,help
used to help even for FOO that aren't pluggable.
The previous two commits fixed the crash bug at a lower layer, so
reverting this one is now safe. Fixes the -device FOO,help
regression, except for the broken devices marked
cannot_even_create_with_object_new_yet. For those, the error message
is improved.
Example of a device where the regression is fixed:
$ qemu-system-x86_64 -device PIIX4_PM,help
PIIX4_PM.command_serr_enable=bool (on/off)
PIIX4_PM.multifunction=bool (on/off)
PIIX4_PM.rombar=uint32
PIIX4_PM.romfile=str
PIIX4_PM.addr=int32 (Slot and optional function number, example: 06.0 or 06)

PIIX4_PM.acpi-pci-hotplug-with-bridge-support=bool

PIIX4_PM.disable_s4=uint8
PIIX4_PM.disable_s3=uint8

Example of a device where it isn't fixed:

qdev: Protect device-list-properties against broken devices
Several devices don't survive object_unref(object_new(T)): they crash
or hang during cleanup, or they leave dangling pointers behind.
This breaks at least device-list-properties, because
qmp_device_list_properties() needs to create a device to find its
properties. Broken in commit f4eb32b "qmp: show QOM properties in
device-list-properties", v2.1. Example reproducer:
$ qemu-system-aarch64 -nodefaults -display none -machine none -S -qmp stdio
{"QMP": {"version": {"qemu": {"micro": 50, "minor": 4, "major": 2}, "package": ""}, "capabilities": []}}
{ "execute": "qmp_capabilities" }
{"return": {}}
{ "execute": "device-list-properties", "arguments": { "typename": "pxa2xx-pcmcia" } }
qemu-system-aarch64: /home/armbru/work/qemu/memory.c:1307: memory_region_finalize: Assertion `((&mr->subregions)->tqh_first == ((void *)0))' failed.
Aborted (core dumped)
[Exit 134 (SIGABRT)]
Unfortunately, I can't fix the problems in these devices right now.
Instead, add DeviceClass member cannot_destroy_with_object_finalize_yet
to mark them:
* Hang during cleanup (didn't debug, so I can't say why):
"realview_pci", "versatile_pci".
* Dangling pointer in cpus: most CPUs, plus "allwinner-a10", "digic",
"fsl,imx25", "fsl,imx31", "xlnx,zynqmp", because they create such
CPUs
* Assert kvm_enabled(): "host-x86_64-cpu", host-i386-cpu",
"host-powerpc64-cpu", "host-embedded-powerpc-cpu",
"host-powerpc-cpu" (the powerpc ones can't currently reach the
assertion, because the CPUs are only registered when KVM is enabled,
but the assertion is arguably in the wrong place all the same)
Make qmp_device_list_properties() fail cleanly when the device is so
marked. This improves device-list-properties from "crashes, hangs or
leaves dangling pointers behind" to "fails". Not a complete fix, just
a better-than-nothing work-around. In the above reproducer,
device-list-properties now fails with "Can't list properties of device
'pxa2xx-pcmcia'".
This also protects -device FOO,help, which uses the same machinery
since commit ef52358 "qdev-monitor: include QOM properties in -device
FOO, help output", v2.2. Example reproducer:
$ qemu-system-aarch64 -machine none -device pxa2xx-pcmcia,help
Before:
qemu-system-aarch64: .../memory.c:1307: memory_region_finalize: Assertion `((&mr->subregions)->tqh_first == ((void *)0))' failed.
After:

tests: Fix how qom-test is run
We want to run qom-test for every architecture, without having to
manually add it to every architecture's list of tests. Commit 3687d53
accomplished this by adding it to every architecture's list
automatically.
However, some architectures inherit their tests from others, like this:
check-qtest-x86_64-y = $(check-qtest-i386-y)
check-qtest-microblazeel-y = $(check-qtest-microblaze-y)
check-qtest-xtensaeb-y = $(check-qtest-xtensa-y)
For such architectures, we ended up running the (slow!) test twice.
Commit 2b8419c attempted to avoid this by adding the test only when
it's not already present. Works only as long as we consider adding
the test to the architectures on the left hand side *after* the ones
on the right hand side: x86_64 after i386, microblazeel after
microblaze, xtensaeb after xtensa.
Turns out we consider them in $(SYSEMU_TARGET_LIST) order. Defined as
SYSEMU_TARGET_LIST := $(subst -softmmu.mak,,$(notdir \
$(wildcard $(SRC_PATH)/default-configs/*-softmmu.mak)))
On my machine, this results in the oder xtensa, x86_64, microblazeel,
microblaze, i386. Consequently, qom-test runs twice for microblazeel
and x86_64.
Replace this complex and flawed machinery with a much simpler one: add
generic tests (currently just qom-test) to check-qtest-generic-y
instead of check-qtest-$(target)-y for every target, then run
$(check-qtest-generic-y) for every target.

trace: remove malloc tracing
The malloc vtable is not supported anymore in glib, because it broke
when constructors called g_malloc. Remove tracing of g_malloc,
g_realloc and g_free calls.
Note that, for systemtap users, glib also provides tracepoints
glib.mem_alloc, glib.mem_free, glib.mem_realloc, glib.slice_alloc
and glib.slice_free.

.travis.yml: Run make check for all targets, not just some
ed173cb ".travis.yml: remove "make check" from main matrix" stopped running
make check for all the Travis build targets for various reasons. It
continued to run make check on one Travis build, which builds for a big
list of all (? nearly all) our supported softmmu targets.
Unfortunately, due to a spacing / quoting error it only actually builds for
the alpha, arm, aarch64 and cris targets. Specifically, the list of
targets is split over several lines. Even with YAML folding, this will
leave spaces in the list, meaning $TARGETS won't have the value we need.
I had a look at the YAML spec and I couldn't quickly see a way of splitting
the list so that it doesn't end up with spaces, so this patch fixes the
problem by putting the whole list on one huge line.
