games/exchess: add forgotten distinfo update after powerpc fix.

Thanks, wiz@

Log message:
games/exchess: Be explicit about needing signed chars.

Fixes build on NetBSD/powerpc where "char" is unsigned.

Log message:
exchess: avoid ambiguous math functions

Log message:
games: Replace RMD160 checksums with BLAKE2s checksums

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

Log message:
games: Remove SHA1 hashes for distfiles

Log message:
games/exchess: update to 7.97beta

Changes since 7.31beta are unknown since the upstream author didn't
document anything.

I just stumbled upon this package because it didn't build with
-Werror=char-subscripts. That bug seems to have been fixed.

Log message:
all: migrate homepages from http to https

pkglint -r --network --only "migrate"

As a side-effect of migrating the homepages, pkglint also fixed a few
indentations in unrelated lines. These and the new homepages have been
checked manually.

Log message:
pkgsrc doesn't support PREFIX with spaces or other special characters.
Therefore it is not necessary to add the :Q modifier to this variable
and several others.

pkglint -r -Wall --autofix --only :Q

Log message:
Add SHA512 digests for distfiles for games category

Problems found locating distfiles:
	Package blokus: missing distfile blokus-1.1.tar.gz
	Package crossfire-client: missing distfile crossfire-client-images-1.11.0.tar.gz
	Package dungeon: missing distfile dungeon-gdt-glk.tar.gz

	Package xskat: missing distfile xskat-cards.tar.gz

Otherwise, existing SHA1 digests verified and found to be the same on
the machine holding the existing distfiles (morden).  All existing
SHA1 digests retained for now as an audit trail.

Log message:
Update games/exchess to v7.31beta, this package's first update in 14 years.

The primary motivator for the upgrade is to improve the book generation
time, which is now several times faster (builds were failing with CPU ulimit
of 1 hour on 3GHz Xeon E5's with the previous version).  This new version
even supports multiple cores, though that isn't enabled at this time.

There appear to have been many other updates, but there is no ChangeLog
and there aren't even any intermediate versions for download (hence using
the current beta version).  Upstream unfortunately makes it as difficult
as possible to see the history of this package.
