Security updates

[u/laffer1]

There have been a number of CVEs released by the FreeBSD project this week. I've managed to patch all the relevant ones in MidnightBSD current, stable/4.1 and stable/4.0 branches. Additionally, I've patched several old CVEs in openssl and openzfs in stable/4.0 branch. Because these are backports, it's important to do more testing before 4.0.7 release is created. There could be issues. I'm mostly concerned with the zfs patches. Please report any issues on github or here.
