Expose the Private Peripheral Interrupt inputs as GPIO inputs.
The layout of the GPIO array is thus:
[0..N-1] SPIs
[N..N+31] PPIs for CPU 0
[N+32..N+63] PPIs for CPU 1
...
Treating PPIs as being another kind of input line is in line with the
GIC architecture specification, where they are clearly described that
way. The 11MPCore TRM is a bit more ambiguous, but there is no practical
difference between "set PPI X as pending" and "0->1 transition on a
PPI input line configured as edge triggered", and PPIs are always
edge triggered, so this change won't affect behaviour.

Move the gic_get_current_cpu() function into arm_gic.c.
There are only two implementations: (1) "get the index
of the currently executing CPU", used by all multicore
GICs, and (2) "always 0", used by all GICs instantiated
with a single CPU interface (the Realview board GIC and
the v7M NVIC). So we can move this into the main GIC
source file.

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 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.

Commit afe0a59535 ("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

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.
