[PATCH v3 1/3] disk: accessors for conditional partition fields

[Heinrich Schuchardt]

Structure disk_partition contains some fields whose existence depends on
configuration variables. Provide macros that return a value irrespective of
the value of configuration. This allows to replace #ifdefs by simple ifs
in codes that relies on these fields which is our preferred coding style.
