Daniel Verkamp 9259324ffb shared_lib: only export spdk_* symbols
Add a basic linker version script to limit exported symbols to those
intended to be public API.  Currently, many internal-only functions are
also named spdk_*, but this will at least limit exported symbols to
those that will not pollute the global namespace.

This also does not assign a version to any symbols; in the future, we
may want to extend the version script to enable ABI compatibility, but
for now, the version script is just used to control symbol visibility.
