monitor: accept input on resume
A chardev may stop trying to write if the associated can_read() callback returned 0. This happens when the monitor is suspended. The frontend is supposed to call qemu_chr_fe_accept_input() when it is ready to accept data again. An issue was observed with a spice port: pending commands may be delayed, as the chardev is not flushed. Most chardev don't use the accept_input() callback, and instead check regularly if they can write. The ones that do use it are braille, mux, msmouse, spice (abstract), spicevmc, spiceport, wctablet.
