chardev/char-pty: send CHR_EVENT_CLOSED on disconnect
Change makes code symmetric to the code, which handles
the "connected" state, i.e. send CHR_EVENT_CLOSED when
state changes from "connected" to "disconnected".
This behavior is similar to char-socket, for example.

chardev/char-hub: implement backend chardev aggregator
This patch implements a new chardev backend `hub` device, which
aggregates input from multiple backend devices and forwards it to a
single frontend device. Additionally, `hub` device takes the output
from the frontend device and sends it back to all the connected
backend devices. This allows for seamless interaction between
different backend devices and a single frontend interface.
The idea of the change is trivial: keep list of backend devices
(up to 4), init them on demand and forward data buffer back and
forth.
The following is QEMU command line example:
-chardev pty,path=/tmp/pty,id=pty0 \
-chardev vc,id=vc0 \
-chardev hub,id=hub0,chardevs.0=pty0,chardevs.1=vc0 \
-device virtconsole,chardev=hub0 \
-vnc 0.0.0.0:0
Which creates 2 backend devices: text virtual console (`vc0`) and a
pseudo TTY (`pty0`) connected to the single virtio hvc console with
the backend aggregator (`hub0`) help. `vc0` renders text to an image,
which can be shared over the VNC protocol. `pty0` is a pseudo TTY
backend which provides biderectional communication to the virtio hvc
console.
'chardevs.N' list syntax is used for the sake of compatibility with
the representation of JSON lists in 'key=val' pairs format of the
util/keyval.c, despite the fact that modern QAPI way of parsing,
namely qobject_input_visitor_new_str(), is not used. Choice of keeping
QAPI list syntax may help to smoothly switch to modern parsing in the
future.

tests/unit/test-char: add unit tests for hub chardev backend
This commit introduces a new test function `char_hub_test` to validate
the functionality and constraints of the "hub" chardev backend in QEMU.
The test includes multiple scenarios:
1. Invalid hub creation:
- Creating a hub without defining `chardevs.N` (expects an error).
- Creating a hub with an embedded multiplexer (`mux=on`) or a chardev
already in use (expects errors).
2. Max backend limit:
- Ensures the hub does not accept more backends than the maximum
allowed, with appropriate error handling.
3. Valid hub creation and data aggregation:
- Successfully creating a hub with two ring buffer backends.
- Verifying data aggregation from backends to a frontend and vice versa.
- Ensuring correct error handling for attempts to attach a hub multiple
times or remove busy chardevs.
4. Extended EAGAIN simulation (non-Windows only):
- Simulates a setup with three backends, including a pipe, to test
EAGAIN handling and watcher behavior.
- Verifies data flow and recovery in scenarios involving buffer
overflows and drained pipes.
The test also ensures correct cleanup of chardevs in all cases, covering
both valid and invalid configurations.

tests/qtest/libqos: add DMA support for writing and reading fw_cfg files
At present, the libqos/fw_cfg.c library does not support the modern DMA
interface which is required to write to the fw_cfg files. It only uses the IO
interface. Implement read and write methods based on DMA. This will enable
developers to add tests that writes to the fw_cfg file(s). The structure of
the code is taken from edk2 fw_cfg implementation. It has been tested by
writing a qtest that writes to a fw_cfg file.

making it no longer possible to connect to qemu -display dbus.
Since p2p connections are gated by existing QMP (or a D-Bus connection),
qemu -display dbus p2p can accept authentication with ANONYMOUS.
