python/qemu/machine: Allow to use other serial consoles than default

Currently the QEMU Python module limits the QEMUMachine class to
use the first serial console.

Some machines/guest might use another console than the first one as
the 'boot console'. For example the Raspberry Pi uses the second
(AUX) console.

To be able to use the Nth console as default, we simply need to
connect all the N - 1 consoles to the null chardev.

Add an index argument, so we can use a specific serial console as

cpu models 'max', 'host', and the current type when KVM is in use.
The logic works well until using machine type none.

For machine type none, cpu_type will be null if cpu option is not
set by command line, strlen(cpu_type) will terminate process.
So We add a check above it.

This won't affect i386 and s390x since they do not use current_cpu.

docs: stop documenting the e1000 NIC model as the default

The default NIC model for QEMU varies per machine type, and is liable to
change across machine type versions. Documenting e1000 NIC as the
default for PC/i386 is thus misleading to users at best. In particular
the PC q35 machine type switched to use e1000e, but only in machine
type versions after 2.11.

Rather than try to explain which NIC model is used for each machine
type version, remove mention of e1000 as the default, and steer users
towards always specifying their desired model.

authz: fix usage of bool in listfile.c

Clean up wrong usage of FALSE and TRUE in places that use "bool" from stdbool.h.

FALSE and TRUE (with capital letters) are the constants defined by glib for
being used with the "gboolean" type of glib. But some parts of the code also use
TRUE and FALSE for variables that are declared as "bool" (the type from <stdbool.h>).
