Login without asking for the username
...
We have wanted to do this since forever, but the last straw was gem5 aarch64,
which runs too fast, and makes it very hard to write "root" withing 60 seconds!
Another possibility to solve that would have been to find an answer for:
https://unix.stackexchange.com/questions/340333/how-can-i-get-bin-login-to-not-timeout
which we didn't, but not typing root at all is even better.
Take this opportunity to document how to login into user0.
sshd: automate and document further

init: disable all userland processes started from init
...
In order to make the system easier to understand.
These include:
* networking
* klogd and syslogd. TODO what are those for? I could not see anything useful that they do.
Also get rid of the useless S20random thing while we are at it.

Disable networking at runtime with lkmc_nonet cli instead of build
...
This is necessary because qemu and gem5 now use the same build folder.
Separate ./run -e and -f for kernel options before and after the ' - '.
This was already the better thing to do when -E was introduced,
but lkmc_nonet prompted me to do it nicer now.
Use the common script to find the out_dir on every toplevel script.
Include usage man pages on README.

This is in preparation for moving parsec to 9p once we get it working on gem5.
We'll document it then when everything is working.

Semi automated conversion, in part because Pandoc is kind of buggy for adoc:
Some of the commands were along the lines:
for f in *.md; do pandoc --atx-headers --base-header-level=3 -o ${f%.md}.adoc --wrap=none $f; done
sed -Ei '/\[\[.*\]\]/d' *.adoc
while read -r f; do cat $f; echo; done <f >g
