Philippe Mathieu-Daudé 083b266f69 chardev: Use QEMUChrEvent enum in IOEventHandler typedef
The Chardev events are listed in the QEMUChrEvent enum.

By using the enum in the IOEventHandler typedef we:

- make the IOEventHandler type more explicit (this handler
  process out-of-band information, while the IOReadHandler
  is in-band),
- help static code analyzers.

This patch was produced with the following spatch script:

  @match@
  expression backend, opaque, context, set_open;
  identifier fd_can_read, fd_read, fd_event, be_change;
  @@
  qemu_chr_fe_set_handlers(backend, fd_can_read, fd_read, fd_event,
                           be_change, opaque, context, set_open);

  @depends on match@
  identifier opaque, event;
  identifier match.fd_event;
  @@
   static
  -void fd_event(void *opaque, int event)
  +void fd_event(void *opaque, QEMUChrEvent event)
   {
   ...
   }

Then the typedef was modified manually in
include/chardev/char-fe.h.

Philippe Mathieu-Daudé 4904ca6a7e monitor/hmp: Explicit we ignore a QEMUChrEvent in IOEventHandler
The Chardev events are listed in the QEMUChrEvent enum. To be
able to use this enum in the IOEventHandler typedef, we need to
explicit an event ignored by this frontend, to silent the
following GCC warning:

    CC      monitor/hmp.o
  monitor/hmp.c: In function ‘monitor_event’:
  monitor/hmp.c:1330:5: error: enumeration value ‘CHR_EVENT_BREAK’ not handled in switch [-Werror=switch]
   1330 |     switch (event) {
        |     ^~~~~~
  cc1: all warnings being treated as errors

Markus Armbruster 54d31236b9 sysemu: Split sysemu/runstate.h off sysemu/sysemu.h
sysemu/sysemu.h is a rather unfocused dumping ground for stuff related
to the system-emulator.  Evidence:

* It's included widely: in my "build everything" tree, changing
  sysemu/sysemu.h still triggers a recompile of some 1100 out of 6600
  objects (not counting tests and objects that don't depend on
  qemu/osdep.h, down from 5400 due to the previous two commits).

* It pulls in more than a dozen additional headers.

Split stuff related to run state management into its own header
sysemu/runstate.h.

Touching sysemu/sysemu.h now recompiles some 850 objects.  qemu/uuid.h
also drops from 1100 to 850, and qapi/qapi-types-run-state.h from 4400
to 4200.  Touching new sysemu/runstate.h recompiles some 500 objects.

Since I'm touching MAINTAINERS to add sysemu/runstate.h anyway, also
add qemu/main-loop.h.

Kevin Wolf fbfc29e3bf monitor: Replace monitor_init() with monitor_init_{hmp, qmp}()
Most callers know which monitor type they want to have. Instead of
calling monitor_init() with flags that can describe both types of
monitors, make monitor_init_{hmp,qmp}() public interfaces that take
specific bools instead of flags and call these functions directly.

Kevin Wolf 920824165c monitor: Split Monitor.flags into separate bools
Monitor.flags contains three different flags: One to distinguish HMP
from QMP; one specific to HMP (MONITOR_USE_READLINE) that is ignored
with QMP; and another one specific to QMP (MONITOR_USE_PRETTY) that is
ignored with HMP.

Split the flags field into three bools and move them to the right
subclass. Flags are still in use for the monitor_init() interface.

Kevin Wolf ed7bda5d07 monitor: Split out monitor/hmp.c
Move HMP infrastructure from monitor/misc.c to monitor/hmp.c. This is
code that can be shared for all targets, so compile it only once.

The amount of function and particularly extern variables in
monitor_int.h is probably a bit larger than it needs to be, but this way
no non-trivial code modifications are needed. The interfaces between HMP
and the monitor core can be cleaned up later.
