53c7c92422 hw/char: Have FEWatchFunc handlers return G_SOURCE_CONTINUE/REMOVE
GLib recommend to use G_SOURCE_REMOVE / G_SOURCE_CONTINUE
for GSourceFunc callbacks. Our FEWatchFunc is a GSourceFunc
returning such value. Use such definitions which are
"more memorable" [*].

bf7b1eab25 chardev: mark explicitly first argument as poisoned
Since commit 9894dc0cdc "char: convert
from GIOChannel to QIOChannel", the first argument to the watch callback
can actually be a QIOChannel, which is not a GIOChannel (but a QEMU
Object).

Even though we never used that pointer, change the callback type to warn
the users. Possibly a better fix later, we may want to store the
callback and call it from intermediary functions.

4f67d30b5e qdev: set properties with device_class_set_props()
The following patch will need to handle properties registration during
class_init time. Let's use a device_class_set_props() setter.

d645427057 Include migration/vmstate.h less
In my "build everything" tree, changing migration/vmstate.h triggers a
recompile of some 2700 out of 6600 objects (not counting tests and
objects that don't depend on qemu/osdep.h).

hw/hw.h supposedly includes it for convenience.  Several other headers
include it just to get VMStateDescription.  The previous commit made
that unnecessary.

Include migration/vmstate.h only where it's still needed.  Touching it
now recompiles only some 1600 objects.

64552b6be4 Include hw/irq.h a lot less
In my "build everything" tree, changing hw/irq.h triggers a recompile
of some 5400 out of 6600 objects (not counting tests and objects that
don't depend on qemu/osdep.h).

hw/hw.h supposedly includes it for convenience.  Several other headers
include it just to get qemu_irq and.or qemu_irq_handler.

Move the qemu_irq and qemu_irq_handler typedefs from hw/irq.h to
qemu/typedefs.h, and then include hw/irq.h only where it's still
needed.  Touching it now recompiles only some 500 objects.

The character frontend needs to be notified that the uart receive buffer
is empty and ready to handle another character.

Previously, the uart only worked correctly when receiving one character

6670b494fd hw/char/cmsdk-apb-uart.c: Correctly clear INTSTATUS bits on writes
The CMSDK APB UART INTSTATUS register bits are all write-one-to-clear.
We were getting this correct for the TXO and RXO bits (which need
special casing because their state lives in the STATE register),
but had forgotten to handle the normal bits for RX and TX which
we do store in our s->intstatus field.

Perform the W1C operation on the bits in s->intstatus too.

977a15f480 hw/arm/mps2: Add UARTs
Add the UARTs to the MPS2 board models.

Unfortunately the details of the wiring of the interrupts through
various OR gates differ between AN511 and AN385 so this can't
be purely a data-driven difference.
