Log message:
mail: Replace RMD160 checksums with BLAKE2s checksums

All checksums have been double-checked against existing RMD160 and
SHA512 hashes

The following distfiles were unfetchable (possibly fetched
conditionally?):

./mail/qmail/distinfo netqmail-1.05-TAI-leapsecs.patch

mail: Remove SHA1 hashes for distfiles

Log message:

  free()-able string.

Log message:
Update to 20201211. From the changelog:

- reup: Delete, because retrying AUTH has been broken ever since TLS was
  added to authup.
- authup: Fix AUTH retries under TLS by inlining the retry logic.
- fixsmtpio: Fix process-management bugs in "Ensure STARTTLS resets all
  state by restarting qmail-smtpd."
- Manual pages: considerably improve clarity of authup(8) and
  fixsmtpio(8). Mention s6-ucspitlsd, a new UCSPI-TLS server
  implementation coming soon to s6-networking.

Log message:
Remove DJB_RESTRICTED, no longer used.

Log message:
Retire 'djbware-errno-hack' and associated options.mk cleverness.
Instead:

1. Package makefiles including their own options.mk
2. Packages say "SUBST_CLASSES+=djberrno" to get the hack, if needed
3. Packages adjust SUBST_FILES.djberrno, if needed

Should fix bulk build failures due to multiple inclusions of options.mk
and/or incorrect definitions of DJB_ERRNO_HACK.

Approved during the freeze by wiz@.
