Two new fields are added in IRC server structure:
- "authentication_method", possible values:
0: not authenticated
1: authenticated with SASL
2: authenticated with other method
- "sasl_mechanism_used", possible values: see enum t_irc_sasl_mechanism
in src/plugins/irc/irc-sasl.h
For buffers with formatted content, the "id" starts to 0 on each buffer and is
incremented on each new line displayed (it is reset to 0 if reaching INT_MAX).
For buffers with free content, the "id" is set to the same value as "y" (ie the
line number, starting to 0).
