The TLS server now checks the client fingerprint. This works, but
is highly experimental. Needs to be refined for practice. Also:
- implemented permittedPeers helper construct to store names
- changed omfwd implementation to use new permittedPeers
- made action logic pass optional auth params only if they are
actually configured
- added new authMode and Fingerprint methods to ptcp netstream
driver (keeping them once again generic)
- added diagnostics messages when invalid auth modes were
configured
This is very experimental and needs some more work. It probably even
segfaults - but the base code is there and running. The rest is
refinement.
While working on this, I did these two bugfixes:
- bugfix: small mem leak in omfwd on exit (strmdriver name was not freed)
- bugfix: $ActionSendStreamDriver had no effect
