This allows kvm acceleration on arm systems that support it. "host" is the
best option I can find right now to attempt to use the acceleration. It
potentially might not be correct but arm systems are sensitive to the
correct values and I don't want to encode the autobuilders CPU type here.

Add the necessary parts to qemuarm64.conf for graphics to be shown in
the SDL window, and USB so that it is possible to interact with it.

Just adding `-device virtio-rng-pci' to the QEMU invocation will
add the device with a default host backend. As of QEMU 1.3+,
the default backend is to use the host's /dev/random as a
source of entropy. [1]
When the entropy pool is empty, reads from /dev/random will
block until additional environmental noise is gathered. [2]
For Yocto, if call runqemu frequently, it will consume lots
of host's /dev/random, and kernel finish crng init in guest get
more and more slowly.
Here are 4 times runqemu boot test:
[ 3.464432] random: crng init done
[ 20.874030] random: crng init done
[ 23.583589] random: crng init done
[ 23.858945] random: crng init done
Modify entropy source to /dev/urandom device on the host which
returns random bytes using a pseudorandom number generator seeded
from the entropy pool. Reads from this device do not block and
kernel finish crng init in guest will not delay.
Of course, the side effect is obviously, we lost the quality of
randomness, but the modification is only on runqemu script
rather than real embedded device, and it benefits oeqa efficiency
in which many cases call runqemu especially multiple oeqa builds
on one host.
After apply the fix:
[ 3.364670] random: crng init done
[ 4.619061] random: crng init done
[ 3.403897] random: crng init done
[ 3.450717] random: crng init done

Fixed:
- Add QB_NETWORK_DEVICE to set network device, it will be used by both
slirp and tap.
- Set QB_NETWORK_DEVICE to "-device virtio-net-pci" in qemuboot.bbclass
but runqemu will default to "-device e1000" when QB_NETWORK_DEVICE is
not set, this is because oe-core's qemu targets support
virtio-net-pci, but the one outside of oe-core may not,
"-device e1000" is more common.
- Set hostfwd by default: 2222 -> 22, 2323 -> 23, and it will choose a
usable port when the one like 222 is being used. This can avoid
conflicts when multilib slirp qemus are running. We can forward more
ports by default if needed, and bsp.conf can custom it.
- Use different mac sections for slirp and tap to fix conflicts when
running both of them on the same host.

Use weak assignment for SERIAL_CONSOLES in qemu configuration files so that
the value could serve as a default value and could be easily overridden in
configuration files like local.conf.
When using the default value for SERIAL_CONSOLES in qemux86-64,we would have
annoying messages on console complaining about respawning getty on ttyS1.
Although the value is set by purpose, at least we need to provide an easy way
to override it.

Not all QEMU machines (outside of those available in OE-Core) are
capable of using the virtio-rng-pci device due to various machine models
not having a pci/virtio bus. This makes it such that the use of the
'-device virtio-rng-pci' flag to QEMU is machine specific.
This patch removes the general addition of the flag to all runqemu
targets and adds the flag into the QB_OPT_APPEND for all the qemu*
machines in OE-Core that support its use (which is all of them).

Current qemu instances all share the same MAC address. This shouldn't be an
issue as they are all on separate network interfaces, however on the slight
chance this is causing problems, its easy enough to ensure we use unique
MAC addresses based on the IP numbers we assign.

Since the qemu for aarch64 must use a virtual console for the second
serial port rather than emulating actual hardware, make sure the correct
device is specified so that a tty is actually started.

qemu can freeze and stop responding if the socket buffer connected to a tcp
serial connection fills up. This happens of course when the reader of
the serial data doesn't actually read it.
This happened in the qemurunner code, because after checking for the
"login:" sentinel, data was never again read from the serial connection.
This patch solves the potential freeze by adding a thread to continuously
read the data from the console and log it. So it also will give a full log
of the console, rather than just up to the login prompt.
To simplify this patch, another serial port was also added to use for the
sole purpose of watching for the sentinel as well as being the interactive
serial port. This will also prevent the possibility of lots of debug
data on the console preventing the sentinel value from being seen due to
interleaved text.

Add machine qemuarm64. The configure files are derived from linaro.
Update:
* rename genericarmv8 to qemuarm64 for coordination in oe-core
* include qemu.inc then remove common part of config
* disable using autoserial
* move arch-armv8.inc from machine/include/arm64 to machine/include/arm
