Notice that this fixes a security issue:
CWE-416 (use after free condition during netjoin processing). No CVE
assigned yet:
https://irssi.org/security/irssi_sa_2017_03.txt
But the 0.8.x series is not believed to be vulnerable to this specific
issue. From the advisory:
Affected versions
-----------------
Irssi up to and including 1.0.1
We believe Irssi 0.8.21 and prior are not affected since a different
code path causes the netjoins to be flushed prior to reaching the use
after free condition.
Openssl is no longer optional, so select it and drop the enable/disable
handling.
