When chardev is multiplexed (mux=on) there are a lot of cases where
CHR_EVENT_OPENED/CHR_EVENT_CLOSED events pairing (expected from
frontend side) is broken. There are either generation of multiple
repeated or extra CHR_EVENT_OPENED events, or CHR_EVENT_CLOSED just
isn't generated at all.
This is mostly because 'qemu_chr_fe_set_handlers()' function makes its
own (and often wrong) implicit decision on updated frontend state and
invokes 'fd_event' callback with 'CHR_EVENT_OPENED'. And even worse,
it doesn't do symmetric action in opposite direction, as someone may
expect (i.e. it doesn't invoke previously set 'fd_event' with
'CHR_EVENT_CLOSED'). Muxed chardev uses trick by calling this function
again to replace callback handlers with its own ones, but it doesn't
account for such side effect.
Fix that using extended version of this function with added argument
for disabling side effect and keep original function for compatibility
with lots of frontends already using this interface and being
"tolerant" to its side effects.
One more source of event duplication is just line of code in
char-mux.c, which does far more than comment above says (obvious fix).

Lukas reported an hard to reproduce QMP iothread hang on s390 that
QEMU might hang at pthread_join() of the QMP monitor iothread before
quitting:

While the iothread is still in the main loop:

#5 0x000003ffad10825a in start_thread
#6 0x000003ffad00dcf2 in thread_start
IMHO it's because there's a race between the main thread and iothread
when stopping the thread in following sequence:
main thread iothread
=========== ==============
aio_poll()
iothread_get_g_main_context
set iothread->worker_context
iothread_stop
schedule iothread_stop_bh
execute iothread_stop_bh [1]
set iothread->running=false
(since main_loop==NULL so
skip to quit main loop.
Note: although main_loop is
NULL but worker_context is
not!)
atomic_read(&iothread->worker_context) [2]
create main_loop object
g_main_loop_run() [3]
pthread_join() [4]
We can see that when execute iothread_stop_bh() at [1] it's possible
that main_loop is still NULL because it's only created until the first
check of the worker_context later at [2]. Then the iothread will hang
in the main loop [3] and it'll starve the main thread too [4].
Here the simple solution should be that we check again the "running"
variable before check against worker_context.

lgtm.com pointed out that commit 678ba275 introduced a shadowed
declaration of local variable 'bs'; thankfully, the inner 'bs'
obtained by 'blk_bs(blk)' matches the outer one given that we had
'blk_insert_bs(blk, bs, errp)' a few lines earlier, and there are
no later uses of 'bs' beyond the scope of the 'if (bitmap)' to
care if we change the value stored in 'bs' while traveling the
backing chain to find a bitmap. So simply get rid of the extra
declaration.

The option -G of usermod command will remove user from other groups
not listed, i.e.: $USER will belong only to group 'docker' after
following the documentation as is.
From usermod(8) manual page:
If the user is currently a member of a group which is not listed,
the user will be removed from the group. This behaviour can be
changed via the -a option, which appends the user to the current
supplementary group list.
This patch improves the situation by adding the -a option to the
usermod command, which will just append user to the supplementary
group list.

It would be legitimate to use libslirp without glib. Let's
add_poll/get_revents pair of callbacks to provide the same
functionality.

Now that polling is done per-instance, we don't need a global list of
slirp instances.

Remove hard-coded dependency on slirp in main-loop, and use a "poll"
notifier instead. The notifier is registered per slirp instance.

Use a more descriptive name for the callback.
Reuse the SlirpWriteCb type. Wrap it to check that all data has been written.
Return a ssize_t for potential error handling and data-loss reporting.

Except for the migration code which is gated by WITH_QEMU, only
include our own headers, so libslirp can be built standalone.

Only slirp actually needs it, and will need it along in libslirp.
