hw/char: Extract serial-mm

hw/char/serial currently contains the implementation of both TYPE_SERIAL and
TYPE_SERIAL_MM. According to serial_class_init(), TYPE_SERIAL is an internal
class while TYPE_SERIAL_MM is used by numerous machine types directly. Let's
move the latter into its own module which makes the dependencies more obvious
and the code more tidy.

The includes and the dependencies have been converted mechanically except in the
hw/char directories which were updated manually. The result was compile-tested.
Now, only hw/char makes direct use of TYPE_SERIAL:

# grep -r -e "select SERIAL" | grep -v SERIAL_
hw/char/Kconfig: select SERIAL
hw/char/Kconfig: select SERIAL
hw/char/Kconfig: select SERIAL
hw/char/Kconfig: select SERIAL
hw/char/Kconfig: select SERIAL

# grep -r -e "/serial\\.h"
include/hw/char/serial-mm.h:#include "hw/char/serial.h"
hw/char/serial-pci-multi.c:#include "hw/char/serial.h"
hw/char/serial.c:#include "hw/char/serial.h"
hw/char/serial-isa.c:#include "hw/char/serial.h"
hw/char/serial-pci.c:#include "hw/char/serial.h"

reset: Use ResetType for qemu_devices_reset() and MachineClass::reset()

Currently, both qemu_devices_reset() and MachineClass::reset() use
ShutdownCause for the reason of the reset. However, the Resettable
interface uses ResetState, so ShutdownCause needs to be translated to
ResetType somewhere. Translating it qemu_devices_reset() makes adding
new reset types harder, as they cannot always be matched to a single
ShutdownCause here, and devices may need to check the ResetType to
determine what to reset and if to reset at all.

This patch moves this translation up in the call stack to
qemu_system_reset() and updates all MachineClass children to use the
ResetType instead.

hw/hppa/machine: Replace g_memdup() by g_memdup2()

Per https://discourse.gnome.org/t/port-your-module-from-g-memdup-to-g-memdup2-now/5538

The old API took the size of the memory to duplicate as a guint,
whereas most memory functions take memory sizes as a gsize. This
made it easy to accidentally pass a gsize to g_memdup(). For large
values, that would lead to a silent truncation of the size from 64
to 32 bits, and result in a heap area being returned which is
significantly smaller than what the caller expects. This can likely
be exploited in various modules to cause a heap buffer overflow.

Replace g_memdup() by the safer g_memdup2() wrapper.

Trivially safe because the argument was directly from sizeof.
