Kirill noticied that on recent versions on QEMU he was not able to
trigger SysRq to invoke debug capabilites of Linux Kernel. He tracked
it down to qemu_chr_be_event() ignoring CHR_EVENT_BREAK due s->be
being NULL. The bug was introduced in 2.8, commit a4afa548fc ("char:
move front end handlers in CharBackend"). Since the commit, the
qemu_chr_be_event() failed to deliver CHR_EVENT_BREAK due to
qemu_chr_fe_init() does not set s->be in case of mux.
Let's fix this by teaching mux to send an event to the frontend with
the focus.

Since there are some issues in memory alloc/free machenism
in glibc for little chunk memory, if Qemu frequently
alloc/free little chunk memory, the glibc doesn't alloc
little chunk memory from free list of glibc and still
allocate from OS, which make the heap size bigger and bigger.
This patch introduce malloc_trim(), which will free heap
memory when there is no rcu call during rcu thread loop.
malloc_trim() can be enabled/disabled by --enable-malloc-trim/
--disable-malloc-trim in the Qemu configure command. The
default malloc_trim() is enabled for libc.

Let's leverage the i8259 common code for kvm-i8259 too.
I think it's still possible that stats can lost when i8259 is in kernel
and meanwhile when irqfd is used, e.g., by vfio or vhost devices.
However that should be rare IMHO since they should be using MSIs mostly
if they really want performance (that's why people use vhost and device
assignment), and no old INTx should be used. As long as the INTx users
are emulated in QEMU the stats will be correct.
For "info pic", it should be always accurate since we fetch kvm regs
before dump.
More importantly, it's just too simple to do this now - it's only 10+
LOC to gain this feature.

We set up the io_mem_rom special memory region using the
unassigned_mem_ops structure; this is then used when a guest tries to
write to ROM. This is incorrect, because the behaviour of unassigned
memory may be different from that of ROM for writes. In particular,
on some architectures writing to unassigned memory generates a guest
exception, whereas writing to ROM is generally ignored. Use a
special readonly_mem_ops for this purpose instead, so writes to
ROM are ignored for all guest CPUs.

some characters to the default UART of a machine can often be done with
some few lines of assembly, so we add the possibility to the boot-serial
tester to use its own mini-kernels or mini-firmwares. We write such images
then into a file that we can load with the "-kernel" or "-bios" parameter
when we launch QEMU.

Booting an s390x guest with -smp 2 and single threaded TCG from disk

Hyper-V has a notion of partition-wide MSRs. Those MSRs are read and
written as usual on each VCPU, however the hypervisor maintains a single
global value for all VCPUs. Thus writing such an MSR from any single
VCPU affects the global value that is read by all other VCPUs.
This leads to an issue during VCPU hotplug: the zero-initialzied values
of those MSRs get synced into KVM and override the global values as has
already been set by the guest.
This change makes the partition-wide MSRs only be synchronized on the
first vcpu.

-iscsi ended up under the "Device URL Syntax" heading by a sequence of
errors, as explained in the previous commit. Move it under the "Block
device options" heading. Nothing left under "Device URL Syntax";
drop the heading.

Commit 0f5314a (v1.0) added section "Device URL Syntax" to
qemu-options.hx. It's enclosed in STEXI..ETEXI, thus affects only
qemu-options.texi, not --help. It appears as a subsection under
section "Invocation". Similarly, qemu.1 has it as a subsection under
"OPTIONS".
Commit f9dadc9 (v1.1.0) dropped new option -iscsi into the middle of
this section. No effect on qemu-options.texi. It appears in --help
run together with the "Bluetooth(R) options:" header.
Commit c70a01e (v1.5.0) gives it is own heading in --help by moving
commit 0f5314a's DEFHEADING(Device URL Syntax:) outside STEXI..ETEXI.
Trouble is the heading makes no sense for -iscsi.
Move all of the "Device URL Syntax" Texinfo to qemu-doc.texi. Mark it
for inclusion in qemu.1 with '@c man begin NOTES'. This turns it into
a separate section outside the list of options both in qemu-doc and in
qemu.1.
There's substantial overlap with the existing qemu-doc section "Disk
Images". Mark with a TODO comment.
Output of --help will be fixed next.

[Unwanted @node dropped]
The table of option parameters lacks @table and @end table. The
parameters become items in the enclosing table of options. Screwed up
when l2tpv3 was added in commit 3fb69aa. Fix the obvious way.

Commit 43f187a broke --help: it put colons into blank lines. It
removed the colon from DEFHEADING(TITLE:) and added it back in the
macro expansion of DEFHEADING(TITLE), so hxtool can emit "@subsection
TITLE" more easily. Trouble is it's added back even for the blank
lines made with DEFHEADING().
Put the colons back where they were before commit 43f187a, and strip
them in hxtool instead.
