janitor: do not include qemu-char everywhere

Touching char/char.h basically causes the whole of QEMU to
be rebuilt. Avoid this, it is usually unnecessary.

aio: introduce AioContext, move bottom halves there

Start introducing AioContext, which will let us remove globals from
aio.c/async.c, and introduce multiple I/O threads.

The bottom half functions now take an additional AioContext argument.
A bottom half is created with a specific AioContext that remains the...

qemu-char: BUGFIX, don't call FD_ISSET with negative fd

tcp_chr_connect(), unlike for example udp_chr_update_read_handler() does
not check if the fd it is using is valid (>= 0) before passing it to
qemu_set_fd_handler2(). If using e.g. a TCP serial port, which is not...

eventfd: making it thread safe

QEMU uses IO handlers to run select() in the main loop.
The handlers list is managed by qemu_set_fd_handler() helper
which works fine when called from the main thread as it is
called when select() is not waiting.

However IO handlers list can be changed in the thread other than...

iohandler: Use bool for boolean struct member and remove holes

Using bool reduces the size of the structure and improves readability.
Two holes in the structure were removed.

iohandlers: fix issue with qemu_set_fd_handler()

As spotted by Aneesh, some users pass a NULL opaque so we need to be more
aggressive in checking whether a user means to unregister.

Also fix a double free caused by tag not being reset to zero after delete....

main: switch qemu_set_fd_handler to g_io_add_watch

This patch changes qemu_set_fd_handler to be implemented in terms of
g_io_add_watch(). The semantics are a bit different so some glue is required.

qemu_set_fd_handler2 is much harder to convert because of its use of polling....

QEMU reap it. In the future it could be enhanced to pass a status,...
