Our Python scripts require Python 2 and will fail on Python 3, eg:
File "/home/petmay01/linaro/qemu-from-laptop/qemu/scripts/qapi-commands.py", line 378
except getopt.GetoptError, err:
^
SyntaxError: invalid syntax
Add a check to configure that Python is not a Python 3, so we can
fail with a comprehensible error rather than an obscure one.

bsd-user doesn't actually support reserving a memory area for the
guest address space, but we need to at least define the reserved_va
global so that cpu-all.h's RESERVED_VA macro will work correctly.
This fixes a compilation error introduced in commit 39879bb
which added a use of RESERVED_VA to h2g_valid().

Often when a guest is stopped from the qemu console, it will report spurious
soft lockup warnings on resume. There are kernel patches being discussed that
will give the host the ability to tell the guest that it is being stopped and
should ignore the soft lockup warning that generates. This patch uses the qemu
Notifier system to tell the guest it is about to be stopped.

The current kvm_init_irq_routing() doesn't set up the used_gsi_bitmap
correctly, and as a consequence pins max_gsi to 32 when it really
should be 1024. I ran into this limitation while testing pci
passthrough, where I consistently got an -ENOSPC return from
kvm_get_irq_route_gsi() called from assigned_dev_update_msix_mmio().

The kvm kernel module includes a number of trace events which can be
useful when debugging system behavior. Even on production systems these
trace events can be used to observe guest behavior and identify the
source of problems.
The kvm_flightrecorder script is a command-line wrapper for the
/sys/kernel/debug/tracing interface. Kernel symbols do not need to be
installed.
This script captures a fixed-size buffer of KVM trace events. Recent
events overwrite the oldest events when the buffer size is exceeded and
it is possible to leave KVM tracing enabled for any period of time with
just a fixed-size buffer. If the buffer is large enough this script is
a useful tool for collecting detailed information after an issue occurs
with a guest. Hence the name "flight recorder".
The script can also be used in 'tail' mode to simply view KVM trace
events as they occur. This is handy for development and to ensure that
the guest is indeed running.

Remove some useless uses of ARCH_CFLAGS -- this variable was never set
so will always be empty. The uses were accidental: in commit 0c439cbf8
Juan Quintela removed ARCH_CFLAGS in favour of CFLAGS (which in turn
became QEMU_CFLAGS). However in commit be17dc90 a use of it was
reintroduced (apparently accidentally) by Michael S. Tsirkin, and then
I subsequently cut-n-pasted that into a number of other configure
feature tests.

Commit afe0a595356192d5f79703cf6462fcc112df007c ("rtl8139: support byte
read to TxStatus registers") reused rtl8139_TxStatus_read() for reading
TxAddr registers. It relies on the fact that TxStatus[] and TxAddr[]
are adjacent.
This causes a gcc warning because the compiler can detect that array
access is out-of-bounds:
hw/rtl8139.c:2501:27: error: array subscript is above array bounds [-Werror=array-bounds]
This patch refactors the function so that we don't rely on out-of-bounds
accesses.

It currently uses qerror_report(), but next commit will convert
the drive_del command to the QAPI and this requires using
error_set().
One particularity of qerror_report() is that it knows when it's
running on monitor context or command-line context and prints the
error message accordingly. error_set() doesn't do this, so we
have to be careful not to drop error messages.
qdev_unplug() has three kinds of usages:
1. It's called when hot adding a device fails, to undo anything
that has been done before hitting the error
2. It's called by function monitor functions like device_del(),
to unplug a device
3. It's used by xen_platform.c in a way that doesn't _seem_ to
be in monitor context
Only item 2 can print an error message to the user, this commit
maintains that.

QEMU host addresses must use uintptr_t to be portable for hosts with
an unusual size of long (w64).
tb_jmp_offset is an uint16_t value, therefore the local variable offset
in function tb_set_jmp_target was changed from unsigned long to uint16_t.
The type cast to long in function tb_add_jump now also uses uintptr_t.
For the bit operation used here, the signedness of the type cast does
not matter.
Some remaining unsigned long values are either only used for ARM assembler
code or will be fixed in a later patch for PPC.
v2:
Fix signature of tb_find_pc in exec.c, too (hint from Blue Swirl, thanks).
There remain lots of other long / unsigned long in exec.c which must be
replaced by uintptr_t. This will be done in a separate patch. Here
only one of these type casts is fixed.
v3:
Also fix signature of page_unprotect.

Code in the float64_to_int32_round_to_zero() function was assuming
that int32 would not be wider than 32 bits; this meant it might

Right now, the main loop is not interrupted when data arrives on a
socket. To fix this, register each socket to interrupt the main loop
with WSAEventSelect. This does not replace select, it only communicates
a change in socket state that requires a select call.
Since the interrupt fires only once per recv call, or only once
after a send call returns EWOULDBLOCK we can activate it on all events
unconditionally. If QEMU is momentarily uninterested on some condition,
the main loop will not busy wait. Instead, it may get one extra wakeup,
but then it will ignore the condition until progress occurs and/or
qemu_set_fd_handler is called to set a callback. At this point the
condition will be tested via select and the callback will be invoked
even if it is still disabled on the event.
