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:
Make games/craft build again.

The custom C++ preprocessor thingy has been choking for a while on
clang; recently gcc's jointed the party. Work around this by building
it with -g instead of -O2. (For me at least with gcc, while -O2
produces a tool that gives spurious syntax errors, plain -O gives one
that loops forever instead, which isn't an improvement.)

Maybe someday someone will bother to find out where the undefined
behavior is.

Also build the actual game with -Wno-return-type to silence complaints
about dead functions not declared as dead and similar, and while here
adjust things so it still installs correctly regardless of umask.

No manual corrections.

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:
Cast argument of sqrt to double to placate Solaris compiler.
Also while here remove one article of pkglint.

Log message:
Rev the distfile patch.
  - roll in patch-xfile.hc
  - fix build with the solaris compiler
  - use snprintf instead of sprintf (mostly)
  - tidy a few things

There is a problem between this thing's precompiler and clang such
that clang builds fail with spurious errors about unterminated string
constants. I don't see what's wrong.

Also, in the course of doing the snprintf changes I discovered that
this depends on both csh and netpbm existing at runtime, so add the
necessary bits.

PKGREVISION -> 4.

Log message:
Fix tautological comparison and (maybe) macos build.
