Start converting `struct odb_source_loose` into a proper pluggable `struct odb_source` by embedding the base struct and assigning it the new `ODB_SOURCE_LOOSE` type. Furthermore, wire up lifecycle management of this source by implementing the `free` callback and taking ownership of the chdir notifications. Note that the loose source is not yet functional as a standalone `struct odb_source`, as it's missing all of the callback implementations. These will be wired up in subsequent commits.
