Log message:

Log message:
textproc: Replace RMD160 checksums with BLAKE2s checksums

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

Unfetchable distfiles (fetched conditionally?):
./textproc/convertlit/distinfo clit18src.zip

Log message:
textproc: Remove SHA1 hashes for distfiles

Log message:
libxml2: don't show non-existent -I/usr/include in "xml2-config --cflags"

Check that the iconv include directory actually exists before adding it
to xml2-config. This fixes build of lang/llvm on Darwin. Bump PKGREVISION.

Log message:
py-libxml2: work around a problem in error handling

Restore part of a patch lost in the last libxml2 update which is still
relevant. Reapplying it fixes segfaults caused by itstool, e.g., when
building editors/pluma, which is PR pkg/56229 from Andrius V.

Quoting from wiz@'s original commit from Jan 9, 2019, which covers
everything else:

"In some cases, invalid UTF-8 strings were returned which caused
Python interpreter crashes. See

itstool/itstool#22

Use a variant of the patch that was used in Fedora.

Bump PKGREVISION."

Fedora is still carrying this patch as-is.

(Also, evidently distinfo was not regenerated properly after the last
update, so there's a diff applied to it unrelated to this change set.)
