[MINI-OS PATCH 1/2] add config support for each Xen library

[Juergen Gross <jgross@suse.com>]

Instead of adding all or no Xen library (controlled by CONFIG_XC),
support a dedicated config option for each library instead. In order
to support older Xen stubdom build versions, let CONFIG_XC enable
all CONFIG_LIBXEN options.
