There are some internals in the libxenstore interface which should be removed. Move those functions into xs_lib.c and the related definitions into xs_lib.h. Remove the functions from the mapfile. Add xs_lib.o to xenstore_client as some of the internal functions are needed there. Bump the libxenstore version to 4.0 as the change is incompatible. Note that the removed functions should not result in any problem as they ought to be used by xenstored or xenstore_client only. Avoid an enum as part of a structure as the size of an enum is compiler implementation dependent. Signed-off-by: Juergen Gross <jgross@suse.com> Acked-by: Ian Jackson <iwj@xenproject.org>
