libsframe: add symbol versioning
Define an empty base version LIBSFRAME_0.0 and add all symbols to
version LIBSFRAME_1.0.
The previous release of libsframe (libsframe.so.0) did not have
versioned symbols. Adding a libsframe.ver file so that future releases
of the library (and its consumers) can manage the changes better.
For Solaris ld, use -M mapfile command line option. libsframe does not
restrict the set of exported symbols, so at this time there is no need
to fall back on the libtool's -export-symbols option for platforms where
some other linker (with a different command line option for symbol
versioning) may be used.
libsframe/
* Makefile.am: Use symbol versioning for libsframe.
* Makefile.in: Regenerated.
* configure: Check for Solaris ld.
* configure.ac: Regenerated.
* libsframe.ver: New file.
