Those calls are either for non-socket fd, or are POSIX-specific. Use the

Some typedefs and macros are defined after the type check macros.
This makes it difficult to automatically replace their
definitions with OBJECT_DECLARE_TYPE.
Patch generated using:
$ ./scripts/codeconverter/converter.py -i \
--pattern=QOMStructTypedefSplit $(git grep -l '' -- '*.[ch]')
which will split "typdef struct { ... } TypedefName"
declarations.
Followed by:
$ ./scripts/codeconverter/converter.py -i --pattern=MoveSymbols \
$(git grep -l '' -- '*.[ch]')
which will:
- move the typedefs and #defines above the type check macros
- add missing #include "qom/object.h" lines if necessary

char_pty_open() prints a "char device redirected to PTY_NAME (label
LABEL)" message to the current monitor or else to stderr. This is not
an error, so it shouldn't go to stderr. Print it to stdout instead.
Why is it even printed? No other ChardevClass::open() prints anything
on success. It's because you need to know PTY_NAME to actually use
this char device, e.g. like e.g. "socat STDIO,cfmakeraw FILE:PTY_NAME"
to use the monitor's readline interface. You can get PTY_NAME with
"info chardev" (a.k.a. query-chardev for QMP), but only if you already
have a monitor.

The lock usage was described with its introduction in commit
9005b2a758. It was necessary because PTY
write() shares more state than GIOChannel with other
operations.
This made char-pty a bit different from other chardev, that only lock
around the write operation. This was apparent in commit
7b3621f47a, which introduced an idle
source to avoid the lock.
By removing the PTY chardev state sharing on write() with previous
patch, we can remove the lock and the idle source.

This doesn't help much compared to the 1 second poll PTY
timer. I can't think of a use case where this would help.
However, we can simplify the code around chr_write(): the write lock
is no longer needed for other char-pty callbacks (see following
patch).

It's a replacement of g_timeout_add[_seconds]() for chardevs. Chardevs
now can have dedicated gcontext, we should always bind chardev tasks
onto those gcontext rather than the default main context. Since there
are quite a few of g_timeout_add[_seconds]() callers, a new function
qemu_chr_timeout_add_ms() is introduced.
One thing to mention is that, terminal3270 is still always running on
main gcontext. However let's convert that as well since it's still part
of chardev codes and in case one day we'll miss that when we move it out
of main gcontext too.
Also, convert all the timers from GSource tags into GSource pointers.
Gsource tag IDs and g_source_remove()s can only work with default
gcontext, while now these GSources can logically be attached to other
contexts. So let's use explicit g_source_destroy() plus another
g_source_unref() to remove a timer.
Note: when in the timer handler, we don't need the g_source_destroy()
any more since that'll be done automatically if the timer handler
returns false (and that's what all the current handlers do).
Yet another note: in pty_chr_rearm_timer() we take special care for
ms=1000. This patch merged the two cases into one.

The idle task will be attached to main gcontext even if the chardev
backend is running in another gcontext. Fix the only caller by
extending the g_idle_add() logic into the more powerful
g_source_attach(). It's basically g_idle_add_full() implementation, but
with the chardev's gcontext passed in.

qemu_chr_be_update_read_handlers() we'll be fine.

It was only passed in by chr_update_read_handlers(). However when
reconnect, we'll lose that context information. So if a chardev was
running on another context (rather than the default context, the NULL
pointer), it'll switch back to the default context if reconnection
happens. But, it should really stick to the old context.
Convert all the callers of io_add_watch_poll() to use the internally
cached gcontext. Then the context should be able to survive even after
reconnections.

We can call qemu_chr_fe_set_handlers() to add/remove fd been watched
in 'context' which can be either default main context or other explicit
context. But the original logic is not correct, we didn't remove
the right fd because we call g_main_context_find_source_by_id(NULL, tag)
which always try to find the Gsource from default context.
Fix it by passing the right context to g_main_context_find_source_by_id().

When a serial port writes data to a pty that's disconnected, drop the
data and return the length dropped. This avoids triggering pointless
retries in callers like the 16550A serial_xmit(), and causes
qemu_chr_fe_write() to write all data to the log file, rather than
logging only while a pty client like virsh console happens to be
connected.
