5734d031aa pc: fix qemu exiting with error when -m X < 128 with old machine types
If machine doesn't support memory hotplug then starting QEMU
with initial memory less than default will make QEMU exit with
following error message:

$QEMU -m 16  -M isapc
qemu-system-i386: "-memory 'slots|maxmem'" is not supported by: isapc

Set maxram_size to initial memory value before parsing
'maxmem' option allows to keep maxmem in sync with initial
memory size if no maxmem option was specified.

bc78cff975 trace: add qemu_system_powerdown_request and qemu_system_shutdown_request trace events
We have the experience that the guest doesn't stop successfully
though it was instructed to shut down.

The root cause may be not in QEMU mostly.  However, QEMU is often
suspected at the beginning just because the issue occurred in
virtualization environment.

Therefore, we need to affirm that QEMU received the shutdown
request and raised ACPI irq from "virsh shutdown" command,
virt-manger or stopping QEMU process to the VM .
So that we can affirm the problems was belonged to the Guset OS
rather than the QEMU itself.

When we stop guests by "virsh shutdown" command or virt-manger,
or stopping QEMU process, qemu_system_powerdown_request() or
qemu_system_shutdown_request() is called. Then the below functions
in main_loop_should_exit() of Vl.c are called roughly in the
following order.

	if (qemu_powerdown_requested())
		qemu_system_powerdown()
			monitor_protocol_event(QEVENT_POWERDOWN, NULL)

	OR

	if(qemu_shutdown_requested()}
		monitor_protocol_event(QEVENT_SHUTDOWN, NULL);

The tracepoint of monitor_protocol_event() already exists, but no
tracepoints are defined for qemu_system_powerdown_request() and
qemu_system_shutdown_request(). So this patch adds two tracepoints for
the two functions. We believe that it will become much easier to
isolate the problem mentioned above by these tracepoints.

abfd9ce341 migration: dump vmstate info as a json file for static analysis
This commit adds a new command, '-dump-vmstate', that takes a filename
as an argument.  When executed, QEMU will dump the vmstate information
for the machine type it's invoked with to the file, and quit.

The JSON-format output can then be used to compare the vmstate info for
different QEMU versions, specifically to test whether live migration
would break due to changes in the vmstate data.

A Python script that compares the output of such JSON dumps is included
in the following commit.

c87b152072 pc & q35: Add new machine opt max-ram-below-4g
This is a pc & q35 only machine opt.

If you add enough PCI devices then all mmio for them will not fit
below 4G which may not be the layout the user wanted. This allows
you to increase the below 4G address space that PCI devices can use
(aka decrease ram below 4G) and therefore in more cases not have any
mmio that is above 4G.

For example using "-machine pc,max-ram-below-4g=2G" on the command
line will limit the amount of ram that is below 4G to 2G.

Note: this machine option cannot be used to increase the amount
of ram below 4G.

74892d2468 vl: allow other threads to do qemu_system_vmstop_request
There patch protects vmstop_requested with a lock and introduces
qemu_system_vmstop_request_prepare.

Together with the new call to qemu_vmstop_requested in vm_start,
qemu_system_vmstop_request_prepare avoids a race where the VM could remain
stopped even though the iostatus of a block device has already been set
(for example).

qemu_system_vmstop_request_prepare however also lets the caller thread
delay observation of the state change until it has itself communicated
that change to the user.  This delay avoids any possibility of a wrong
reordering of the BLOCK_IO_ERROR event and the subsequent STOP event.

c270fb9eff vl.c: extend -m option to support options for memory hotplug
Add following parameters:
  "slots" - total number of hotplug memory slots
  "maxmem" - maximum possible memory

"slots" and "maxmem" should go in pair and "maxmem" should be greater
than "mem" for memory hotplug to be enabled.

2d9c2725f7 vl.c: daemonize before guest memory allocation
memory allocated for guest before QEMU is daemonized and then mapped
later in guest's address space after it is daemonized, leads to EPT
violation and QEMU aborts.

To avoid this and similar issues switch to daemonized mode early
before applying/processing other options.

5b808275f3 trace: Multi-backend tracing
Adds support to compile QEMU with multiple tracing backends at the same time.

For example, you can compile QEMU with:

  $ ./configure --enable-trace-backends=ftrace,dtrace

Where 'ftrace' can be handy for having an in-flight record of events, and 'dtrace' can be later used to extract more information from the system.

This patch allows having both available without recompiling QEMU.

9f9260a3be qdev: Display warning about unused -global
This can help a user understand why -global was ignored.

For example: with "-vga cirrus"; "-global vga.vgamem_mb=16" is just
ignored when "-global cirrus-vga.vgamem_mb=16" is not.

This is currently clear when the wrong property is provided:

out/x86_64-softmmu/qemu-system-x86_64 -global cirrus-vga.vram_size_mb=16 -monitor pty -vga cirrus
char device redirected to /dev/pts/20 (label compat_monitor0)
qemu-system-x86_64: Property '.vram_size_mb' not found
Aborted (core dumped)

vs

out/x86_64-softmmu/qemu-system-x86_64 -global vga.vram_size_mb=16 -monitor pty -vga cirrus
char device redirected to /dev/pts/20 (label compat_monitor0)

5b9d313e3f vl: fix 'name' option to work with -readconfig
The 'name' option silently failed when used in config files
( http://lists.gnu.org/archive/html/qemu-devel/2014-04/msg00378.html )

-readconfig stores the configuration read in QemuOpts.  Command line
option parsing should do the same, and no more.  In particular it should
not act upon the option.  That needs to be done separately, where both
command line and -readconfig settings are visible in QemuOpts.

02ce232c50 vl.c: remove init_clocks call from main
Clocks are initialized in qemu_init_main_loop. They are not needed before it.
Initializing them twice is not only unnecessary but is harmful: it results in
memory leak and potentially can lead to a situation where different parts of
QEMU use different sets of timers.

To avoid it remove init_clocks call from main and add an assertion to
qemu_clock_init that corresponding clock has not been initialized yet.
