Unpack xen_features into an array of u8 'booleans'
This allows us to avoid including bitops.h all over the tree as well
as avoiding any potential endianness issues in the future.
Use __read_mostly on the xen_features array now that the tree is based
on a version of Linux which supports it.
Also export xen_features for use in modules.
