[UNIKRAFT PATCH v2 0/9] General 9pfs and vfscore improvements

[Cristian Banu <cristb@xxxxxxxxx>]

This patch series adds general 9pfs improvements, for correctness,
readability and performance.

Changes since v1:
- The vfscore improvements have been upstreamed directly from v1, so
they are no longer present in v2.
- Split the serialization rewrite patch into four smaller patches.
- Removed the `uk_9p_trace_message{,_end}` traces, as they were too
verbose.
- Fixed a typo in a uk_9p_version comment.

  lib/uk9p: Switch to using the new serialization
  lib/uk9p: Delete the old serialization
