[Xen-devel] [PATCH] library soname versions

[Ian Jackson <Ian.Jackson@xxxxxxxxxxxxx>]

The attached patch:
 * Arranges for the sonames of libxenstore, libxc and libblktap
   to be set from a single place in Config.mk.
 * Bumps the soname major version number to 3.2 in preparation for
   3.2 rc1 after which we do not expect to have ABI changes.

I have not done anything about libaio, libfsimage and libflask.  The
former two are from important elsewhere and if we're lucky will have
sane versioning upstream.

libflask has a very small interface and I'm hoping that the XSM
authors have been keeping some ABI discipline.
