This commit switches UID hashing from md5 to a highway hash. It also
moves the salt value out of the file plugin - and makes it
installation-specific instead - it is moved to the global namespace.
There now are digest hash functions to make "static"
installation-specific hashes that are stable over workers available to
everyone; hashes can be 64, 128 or 256 bits in size.
Due to the fact that we switch the file hashing algorithm, all file
hashes change.
The underlyigng algorithm that is used for hashing is highwayhash-128,
which is significantly faster than md5.
These are no longer loaded by default due to the performance impact they
cause simply by being loaded (they have event handlers for commonly
generated events) and they aren't generally useful enough to justify it.
This makes conn.logs a bit prettier (and smaller) because all lines that
do not use a tunnel will now have a "-" instead of the "(empty)" for
tunnel_parents.
- Moved the Notice::notice event and Notice::policy table to both be hooks.
- Renamed the old Notice::policy to Notice::policy_table and documented it as deprecated.
In the *service* field of connection records, GridFTP control channels
are labeled as "gridftp" and data channels as "gridftp-data".
Added *client_subject* and *client_issuer_subject* as &log'd fields to
SSL::Info record. Also added *client_cert* and *client_cert_chain*
fields to track client cert chain.
