[PATCH 0/7] odb: unify read and write streams

Hi,

we have two different kind of object database streams in our code base:
`odb_write_stream` and `odb_read_stream`. While those are used for
different use cases, the provided functionality is ultimately the exact
same.

This patch series thus refactors these streams so that we have a single
`odb_stream`, only. This allows us to reuse the streams for different
kinds of purposes and makes them more generally useful overall. For
example, it's trivially possible now to create an object stream for any
given object and then write that stream into a different source.

The series is built on top of 5b2471720c (The 10th batch, 2026-08-03).

Thanks!

Patrick
