Move all the bios_* fields into a separate struct. Not only this
simplifies the code a bit it also helps us to identify whether BIOS
info is present. We don't have to check all the four variables for
being not-NULL, but we can just check the pointer to the struct.

In "src/util/" there are many enumeration (enum) declarations.
Sometimes, it's better using a typedef for variable types,
function types and other usages. Other enumeration will be
changed to typedef's in the future.
