[bug#27374] Update Knot DNS to 2.5.1.

[-- Attachment #1.1: Type: text/plain, Size: 582 bytes --]

[Ack! It's been so long that I forgot how to list. This was meant for
guix-patches, not bug-guix, of course...]

Guix,

Knot DNS >=2.5 uses a new, LMDB-based (DNSSEC) key database format. It
ships a new ‘pykeymgr’ script to manually migrate keys from the older
JSON format.

These patches update Knot to 2.5.1, add the required python-lmdb
bindings, and throw in a real LMDB description for good measure.

I use Knot 2.5.1 & DNSSEC but haven't any 2.4-format key databases to
import. If you do, your feedback would be very welcome.

Kind regards,

T G-R

‘lib/win32/inttypes.h’ and ‘lib/win32-stdint/stdint.h’ are straight
BSD-3. Not sure whether to add it to the list or just delete the files
since they'll never be used under GNU. I'll do the former by default.

Kind regards,

T G-R
