[kvm-unit-tests,0/3] s390x: Improve console handling

Message

Console IO is and has been in a state of "works for me". I don't think
that will change soon since there's no need for a proper console
driver when all we want is the ability to print or read a line at a
time.

However since input is only supported on the ASCII console I was
forced to use it on the HMC. The HMC generally does not add a \r on a
\n so each line doesn't start at column 0. It's time to finally fix
that.

Also, since there are environments that only provide the line-mode
console it's time to add line-mode input to properly support them.

v1:
	* Fenced ASCII compat handling so it's only use in LPAR
	* Squashed compat handling into one patch
	* Added an early detect_host since SCLP might be used in setup
	* Fixed up a few formatting issues in input patch
	* Fixed up copyright stuff
