The special target should not be needed anymore, and caused (perhaps
due to a Make bug) a failure with "make -j2".  In any case, the
main makefile is a better place for such special targets rather
than an included makefile.

Instruction breakpoint/zero overhead loop handling code is built into
TBs pointed to by IBREAKA/LEND SRs. When these or related SRs get
changed TBs at virtual addresses corresponding to their old and their
new values must be invalidated.

Virtual address range is passed to the tb_invalidate_phys_page_range,
which is incorrect in system emulation mode.

To fix it use guest TLB/MMU to translate virtual address to physical
address.

However the guest may not have virtual-to-physical mapping at the moment
of IBREAKA/LEND change, thus this fix is not 100% accurate.

The GLib threading APIs were revamped in GLib 2.31 and a number
of the old interfaces were deprecated, which means they provoke
compilation warnings (errors if -Werror) now. Add support for the
new interfaces while retaining the old ones so we can still compile
on older versions of GLib too.

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.

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.
