Move datastore and btree code from searchlib to vespalib

Namespace is still `search` and not `vespalib` due to the massive
amount of code that would need to be modified for such a change.

Other changes:
- Move `BufferWriter` from searchlib to vespalib
- Move assertion and rand48 utilities from staging_vespalib to vespalib
- Move gtest utility code from staging_vespalib to vespalib
