mod_saslauth, mod_c2s: Disable tls-server-end-point channel binding by default
This channel binding method is now enabled when a hash is manually set in the
config, or it attempts to discover the hash automatically if the value is the
special string "auto".
A related change to mod_c2s prevents complicated certificate lookups in the
client connection hot path - this work now happens only when this channel
binding method is used. I'm not aware of anything else that uses ssl_cfg (vs
ssl_ctx).
Rationale for disabling by default:
- Minor performance impact in automatic cert detection
- This method is weak against a leaked/stolen private key (other methods such
as 'tls-exporter' would not be compromised in such a case)
Rationale for keeping the implementation:
- For some deployments, this may be the only method available (e.g. due to
TLS offloading in another process/server).
