Changes

ctf.core: Parse event fragments and strings

Implement parsing of all json events and add null-terminated string
handling. Data stream fragment handling has not been implemented yet,
but the if-statement was added. To test, use [1] succeed1 CTF2 trace.

releng: Update e4.29 and eStaging targets for 2023-09 M2

Orbit project is undergoing major changes. Use new orbit-aggregation
repository.

org.apache.commons.commons-io in the new repository.
