Having creation as a member of the CharDriver struct removes the need
to export functions for qemu-char.c's usage. After the conversion,
chardev backends implemented outside qemu-char.c will not need a stub
creation function anymore.
Ultimately all drivers will be converted. For now, support the case
where cd->create == NULL.

g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer,
for two reasons. One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.
This commit only touches allocations with size arguments of the form
sizeof(T). Same Coccinelle semantic patch as in commit b45c03f.

Now we have removed the legacy register_char_driver() we can
rename register_char_driver_qapi() to the more obvious and
shorter name.

From: Paolo Bonzini <pbonzini@redhat.com>
chr-testdev enables a virtio serial channel to be used for guest
initiated qemu exits. hw/misc/debugexit already enables guest
initiated qemu exits, but only for PC targets. chr-testdev supports
any virtio-capable target. kvm-unit-tests/arm is already making use
of this backend.
Currently there is a single command implemented, "q". It takes a
(prefix) argument for the exit code, thus an exit is implemented by
writing, e.g. "1q", to the virtio-serial port.
It can be used as:
$QEMU ... \
-device virtio-serial-device \
-device virtserialport,chardev=ctd -chardev testdev,id=ctd
or, use:
$QEMU ... \
-device virtio-serial-device \
-device virtconsole,chardev=ctd -chardev testdev,id=ctd
to bind it to virtio-serial port0.
