The function gic_set_pending_private() is now used by the NVIC
only (for the GIC we now set PPI interrupts via gpio lines and
gic_set_irq()). So make it #ifdef NVIC and remove the 'attribute
unused' annotation.

Now all the A profile cores have been switched to use the standalone
sysbus GIC, the only remaining code which #includes arm_gic.c is
the v7M NVIC. The coupling is much closer here so it's not so
easily disentangled. For now, add a comment about how arm_gic.c
is compiled, and assume that the NVIC always includes arm_gic.c
and the non-NVIC GIC is always compiled standalone.

Make gic_reset a sysbus reset function, so we actually
reset the GIC on system reset rather than only at init.
For the NVIC this requires us also to implement reset
of the SysTick.

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.

Move the NCPU definition to arm_gic.c: the maximum number
of CPU interfaces is defined by the GIC architecture specification
to be 8, so we don't need to have this #define in each of the

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
not correctly detect the overflow case. We take the simple approach

for other float sizes.

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.

Add support for ARM BE8 userspace binaries.
i.e. big-endian data and little-endian code.
In principle LE8 mode is also possible, but AFAIK has never actually
been implemented/used.
System emulation doesn't have any useable big-endian board models,
but should in principle work once you fix that.
Dynamic endianness switching requires messing with data accesses,
preferably with TCG cooperation, and is orthogonal to BE8 support.
