Rename the gic_state struct to match QEMU's coding style conventions
for structure names, since the impending KVM-for-ARM patches will
create another subclass of it. This patch was created using:
sed -i 's/gic_state/GICState/g' hw/arm_gic.c hw/arm_gic_common.c \
hw/arm_gic_internal.h hw/armv7m_nvic.c

There is a gap in the reset region of the address space at offset 0x208. This
throws out all these enum values by one when translating them to address offsets.
Fixed by putting the corresponding gap in the enum as well.

The 'struct tm now' field in the state structure is in fact only
ever used as a temporary (the actual RTC state is held in 'offset').
Remove it from the state structure in favour of using local variables
to avoid confusion about whether it needs to be saved on migration.

Correct several deficiencies in the handling of the register pointer:
* it should wrap around after 0x3f, not 0xff
* guard against the caller handing us an out of range pointer
(on h/w this can never happen, because only a 7 bit value is
transferred over the I2C bus)
* there was confusion over whether nvram[] holds only the 56 bytes
of guest-accessible NVRAM, or also the secondary registers
which hold the value of the clock captured at the start of a
multibyte read. Correct to consistently be the latter, by fixing
the array size and the offset used for NVRAM writes.
* ds1338_send was attempting to use 'data' as both the data and
the register offset simultaneously, which meant that writes to
any register were broken; fix to use the register pointer.

A missing call to qemu_set_irq() when reading the IRQ register
required SW to write to the IRQ register to acknowledge an
interrupt. With this patch the behavior is fixed:
- Reading the interrupt register clears it and updates the timers
interrupt status
- Writes to the interrupt register are ignored

According to the spec we must raise an interrupt when one is requested
even for non active tds.
Linux depends on this, for bulk transfers it runs an inactivity timer
to work around a bug in early uhci revisions, when we take longer then
200 ms to process a packet, this timer goes of, and as part of the
handling Linux then unlinks the qh, and relinks it after the frindex
has increased by atleast 1, the problem is Linux only checks for the
frindex increases on an interrupt, and we don't send that, causing
the qh to go inactive for more then 32 frames, at which point we
consider the packet cancelled.

DO_UPCAST is supposed to translate from the first member of a struct to
that struct, not from arbitrary ones. And it (usually) breaks the build
when neglecting this rule. Use container_of to fix the build breakage
and likely also the runtime behavior.

Blue Swirl reports that Clang doesn't like the structure we define to
avoid dynamic allocation for a number of calls to VFIO_DEVICE_SET_IRQS.
Adding an element after a variable sized type is a GNU extension.
Switch back to dynamic allocation, which really isn't a problem since
this is only done on interrupt setup changes.

We try to do lazy initialization of MSIX since we don't actually need
to setup anything until MSIX vectors start getting used. This leads
to problems if MSIX is enabled, but never used (we can end up trying
to re-enable INTx while it's still enabled). We also run into
problems trying to expand our reset function to tear down interrupts
as we can then get vector release notifications after we've released
data structures. By making explicit initialization and teardown we
can avoid both of these problems and behave more similar to bare
metal.

Occasionally we get regions added that overlap with existing mappings.
These always seems to be in the VGA ROM range. VFIO returns EBUSY
for these mapping attempts. We can try a little harder and assume
that the latest mapping is correct by removing any overlapping ranges
and retrying the original request.

We can't afford the overhead of switching out and back into mmap mode
around each interrupt, but we can do it lazily via a timer. On INTx
interrupt, disable the mmap'd memory regions and set a timer. On
every interrupt, push the timer out. If the timer expires and the
interrupt is no longer pending, switch back to mmap mode.
This has the benefit that things like graphics cards, which rarely or
never, fire an interrupt don't need manual user intervention to add
the x-intx=off parameter. They'll just remain in mmap mode until they
trigger an interrupt, and if they don't continue to regularly fire
interrupts, they'll switch back.
The default timeout is tuned for network cards so that a ping is just
enough to keep them in non-mmap mode, where they have much better
latency. It is tunable with an experimental option,
x-intx-mmap-timeout-ms. A value of 0 keeps the device in non-mmap
mode after the first interrupt.
It's possible we could look at the class code of devices and come up
with reasonable per-class defaults based on expected interrupt
frequency and latency. None of this is used for MSI interrupts and
also won't be used if we can bypass through KVM.

With the next qemu version (1.3) we are going to bump the qxl device
revision to 4. The new features available require a recent spice-server
version, so raise up the bar. Otherwise we would end up with different
qxl revisions depending on the spice-server version installed, which
would be a major PITA when it comes to compat properties.
