In order to support generic parameter parsing carve out the parser from
_cmdline_parse(). As this generic function might be called after boot
remove the __init annotations from all called sub-functions.

Currently parameters of the hypervisor (e.g. console log level) can be
set via boot command line. Instead of having to reboot the system in
case another setting is desired, being able to modify many of those
parameters at runtime would be the better option.
This patch series addresses this by addi
