[RFC PATCH 13/14] hw/char/terminal3270: Explicit ignored QEMUChrEvent in IOEventHandler

[Philippe Mathieu-Daudé]

The Chardev events are listed in the QEMUChrEvent enum. To be
able to use this enum in the IOEventHandler typedef, we need to
explicit when frontends ignore some events, to silent GCC the
following warnings:

    CC      s390x-softmmu/hw/char/terminal3270.o
  hw/char/terminal3270.c: In function ‘chr_event’:
  hw/char/terminal3270.c:156:5: error: enumeration value ‘CHR_EVENT_BREAK’ not 
handled in switch [-Werror=switch]
    156 |     switch (event) {
        |     ^~~~~~
  hw/char/terminal3270.c:156:5: error: enumeration value ‘CHR_EVENT_MUX_IN’ not 
handled in switch [-Werror=switch]
  hw/char/terminal3270.c:156:5: error: enumeration value ‘CHR_EVENT_MUX_OUT’ 
not handled in switch [-Werror=switch]
  cc1: all warnings being treated as errors
