Breaking Changes for 14.X.X

[Dav1dde]

Random collection of API changes we should do for 14.X.X

• SourceBundleWriter:
  • finish should return back the Writer
  • API duplication for write_object* should probably be a single function
  • Consider shrinking the API surface and moving all settings which are only necessary for write_object into a arguments struct that is passed into write object.
• symbolic-ppdb:
  • EmbeddedSource::get_contents_bounded can be renamed to get_contents, the old get_contents removed.
  • The sole field of FormatErrorKind::InvalidBlobFormat should have type i32 instead of u32.
• CfiCache:
  • Cleanup the API around from_object_with_opts instead use some builder pattern that allows us to provide the options.
