Switch the mss-timer code away from bottom-half based ptimers to
the new transaction-based ptimer API. This just requires adding
begin/commit calls around the various places that modify the ptimer
state, and using the new ptimer_init() function to create the timer.

In my "build everything" tree, changing sysemu/sysemu.h triggers a
recompile of some 5400 out of 6600 objects (not counting tests and
objects that don't depend on qemu/osdep.h).
Almost a third of its inclusions are actually superfluous. Delete
them. Downgrade two more to qapi/qapi-types-run-state.h, and move one
from char/serial.h to char/serial.c.
hw/semihosting/config.c, monitor/monitor.c, qdev-monitor.c, and
stubs/semihost.c define variables declared in sysemu/sysemu.h without
including it. The compiler is cool with that, but include it anyway.
This doesn't reduce actual use much, as it's still included into
widely included headers. The next commit will tackle that.

Many places including hw/qdev-properties.h (directly or via hw/qdev.h)
actually need only hw/qdev-core.h. Include hw/qdev-core.h there
instead.
hw/qdev.h is actually pointless: all it does is include hw/qdev-core.h
and hw/qdev-properties.h, which in turn includes hw/qdev-core.h.
Replace the remaining uses of hw/qdev.h by hw/qdev-properties.h.

Touching hw/qdev-properties.h now recompiles some 1200 objects.

Back in 2016, we discussed[1] rules for headers, and these were
generally liked:
1. Have a carefully curated header that's included everywhere first. We
got that already thanks to Peter: osdep.h.
2. Headers should normally include everything they need beyond osdep.h.
If exceptions are needed for some reason, they must be documented in
the header. If all that's needed from a header is typedefs, put
those into qemu/typedefs.h instead of including the header.
3. Cyclic inclusion is forbidden.
This patch gets include/ closer to obeying 2.
It's actually extracted from my "[RFC] Baby steps towards saner
headers" series[2], which demonstrates a possible path towards
checking 2 automatically. It passes the RFC test there.

The PL031 RTC tracks the difference between the guest RTC
and the host RTC using a tick_offset field. For migration,
however, we currently always migrate the offset between
the guest and the vm_clock, even if the RTC clock is not
the same as the vm_clock; this was an attempt to retain
migration backwards compatibility.
Unfortunately this results in the RTC behaving oddly across
a VM state save and restore -- since the VM clock stands still
across save-then-restore, regardless of how much real world
time has elapsed, the guest RTC ends up out of sync with the
host RTC in the restored VM.
Fix this by migrating the raw tick_offset. To retain migration
compatibility as far as possible, we have a new property
migrate-tick-offset; by default this is 'true' and we will
migrate the true tick offset in a new subsection; if the
incoming data has no subsection we fall back to the old
vm_clock-based offset information, so old->new migration
compatibility is preserved. For complete new->old migration
compatibility, the property is set to 'false' for 4.0 and
earlier machine types (this will only affect 'virt-4.0'
and below, as none of the other pl031-using machines are
versioned).

The timer controller can be driven by either an external 1MHz clock or
by the APB clock. Today, the model makes the assumption that the APB
frequency is always set to 24MHz but this is incorrect.
The AST2400 SoC on the palmetto machines uses a 48MHz input clock
source and the APB can be set to 48MHz. The consequence is a general
system slowdown. The QEMU machines using the AST2500 SoC do not seem
impacted today because the APB frequency is still set to 24MHz.
We fix the timer frequency for all SoCs by linking the Timer model to
the SCU model. The APB frequency driving the timers is now the one
configured for the SoC.

The actual single GPT definition was no good enough and because of it
booting the sabrelite board with a i.MX6DL device tree would fail
because of an incorrect input clock definition for the i.MX6DL SOC.
This patch fixes the i.MX6DL boot failure by adding the ability to

This implements the prescaler and source fields of the timer control
register. The source for each timer can be selected among 4 clock
inputs whose frequencies are set through model properties.

The model was generating interrupts for all enabled timers after the
expiration of one of them. Avoid this by passing explicitly the timer
index to the callback function.

Most notably this includes changes to exec to support
full 64 bit addresses.
This also flushes out patches that got queued during 1.7 freeze.
There are new tests, and a bunch of bug fixes all over the place.
There are also some changes mostly useful for downstreams.
I'm also listing myself as pc co-maintainer. I'm doing this reluctantly,
but this seems to be necessary to make sure patches are not lost or delayed too
much, and posting the MAINTAINERS patch did not seem to make anyone else
volunteer.

The ARM A9 MPCore has a timer that is global to all cores in the cluster.
The timer is shared but each core has a private independent comparator
and interrupt.

Instead of having the parent provide PITCommonClass::init,
let the children override DeviceClass::realize themselves.
This pushes the responsibility for saving and calling the parent's
realizefn to the children.

Many of these should be cleaned up with proper qdev-/QOM-ification.
Right now there are many catch-all headers in include/hw/ARCH depending
on cpu.h, and this makes it necessary to compile these files per-target.
However, fixing this does not belong in these patches.
