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.

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.

This lead to an infinite chaing of refactorings:
Fix arm and aarch64 lx-symbols
This was just by chance, a continue GDB command was needed before running it.
I noticed that there is no more need for the x86 GDB --ex 'set arch i386:x86-64:intel'
thing and unified all archs. TODO bisect where that was fixed and understand why.
Add debug kernel configs for gem5 kernel.
Document gem5 aarch64 gdb debug doesn't work.
Document tmux split pane action.

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.
