Jakob Borg d19b12d3fe lib/protocol: Buffer allocation when compressing (fixes #6146) (#6147) ...

We incorrectly gave a too small buffer to lz4.Compress, causing it to
allocate in some cases (when the data actually becomes larger when
compressed). This then panicked when passed to the buffer pool.

This ensures a buffer that is large enough, and adds tripwires closer to
the source in case this ever pops up again. There is a test that
exercises the issue.
