Commit partial update to 1.22 so I can work on it on multiple
machines. Doesn't build yet, so leave the package marked BROKEN.
Update to 1.22.
Does not include all the changes in PR 45318, some of which need
further investigation.

pkgsrc changes:
   - update MASTER_SITES and HOMEPAGE
   - remove LP64 restriction (LP64 platforms are supported using -m32)
   - add destdir support (provided by upstream) and lift BROKEN
   - remove some pkglint
   - mark MAKE_JOBS_SAFE=no
   - add readline.bl3.mk
   - patch-ag was applied upstream
   - remove patch-ah and handle the issue involved a cleaner way

Caution: so far the LP64 build does not actually work yet, -m32
notwithstanding; it dies with
   PreludeList.init: empty list
   PreludeList.init: empty list
   PreludeList.init: empty list
i386 works though.
