janitor: do not rely on indirect inclusions of or from qemu-char.h

Various header files rely on qemu-char.h including qemu-config.h or
main-loop.h, but they really do not need qemu-char.h at all (particularly
interesting is the case of the block layer!). Clean this up, and also...

Revert "qemu-char: Print strerror message on failure" and deps

The commit's purpose is laudable:

The only way for chardev drivers to communicate an error was to

spice-qemu-char: Generate chardev open/close events

Define a state callback and make that generate chardev open/close events when
called by the spice-server.

Notes:

the code ignores these events for a spicevmc with a subtype of vdagent, this...

qemu-char: Print strerror message on failure

The only way for chardev drivers to communicate an error was to return a NULL

spice-qemu-char: Fix flow control in client -> guest direction

In the old spice-vmc device we used to have:
last_out = virtio_serial_write(&svc->port, p, MIN);
if (last_out > 0)
...

Now in the chardev backend we have:
last_out = MIN;...

Note the vmc_register_interface() in spice_chr_write is left in place
in case someone uses spice-chardev with a frontend which does not have
guest open / close notification.

For usage by spice vdagent in conjunction with a properly named
virtio-serial device, and future smartcard channel usage....
