Implement a rudimentary form only.
extra_params can get long when passing a lot of arguments to qemu.
Multiline strings help with readability of the .cfg file.
Multiline strings begin and end with """, which must occur on separate
lines.
For example:
extra_params = """-cpu max,ctop=on -smp cpus=1,cores=16,maxcpus=128 \
-append '-drawers 2 -books 2 -sockets 2 -cores 16' \
-device max-s390x-cpu,core-id=31,drawer-id=0,book-id=0,socket-id=0"""
The command string built with extra_params is eval'ed by the runtime
script, so the newlines need to be escaped with \.

This could certainly be done differently, suggestions welcome.
