[MINI-OS PATCH v2] add config support for each Xen library

[Juergen Gross <jgross@xxxxxxxx>]

Instead of adding all or no Xen library (controlled by CONFIG_XC),
support a dedicated config option for each library instead,
defaulting to disabled.

As it is no longer needed now, drop the CONFIG_XC support.

V2:
- merge patches of the V1 series (Samuel Thibault)

Note: do not apply to the tree until the related Xen series
"stubdom: prepare more fine grained Xen library usage" has been
applied.
