3d9e232240 char: update the mux handlers in class callback
Instead of handling mux chardev in a special way in
qemu_chr_fe_set_handlers(), we may use the chr_update_read_handler
class callback instead.

c7278b4355 chardev: introduce chr_machine_done hook
Introduce ChardevClass.chr_machine_done() hook so that chardevs can run
customized procedures after machine init.

There was an existing mux user already that did similar thing but used a
raw machine done notifier.  Generalize it into a framework, and let the
mux chardevs provide such a class-specific hook to achieve the same
thing.  Then we can move the mux related code to the char-mux.c file.

Since at it, replace the mux_realized variable with the global
machine_init_done varible.

This notifier framework will be further leverged by other type of
chardevs soon.

4d43a603c7 char: move CharBackend handling in char-fe unit
Move all the frontend struct and methods to a seperate unit. This avoids
accidentally mixing backend and frontend calls, and helps with readabilty.

Make qemu_chr_replay() a macro shared by both char and char-fe.

Export qemu_chr_write(), and use a macro for qemu_chr_write_all()

(nb: yes, CharBackend is for char frontend :)
