Summary:
This allows us to incrementally abstract away parts related to filesystem from
Log. For example, instead of using std::fs to access filesystem directly, use
methods on the GenericPath instead.
Right now the main motivation is to add support for "multi-logs" sharing a single meta
file. To do that, methods reading and writing metas are moved to the
GenericPath type.
This also unifies the open functions. Now OpenOptions::create_in_memory can be
private. Empty in-memory Logs can be opened via `open(())`.
