awk: document updating
Fill in all the details to the standard process so they are hand in one
place and don't need to be re-remembered or rediscovered for the next
import.

+Notes on upgrading awk from upstream
+
+FreeBSD imports awk from the one true awk github project. This is the blessed
+successor to Brian Kernighan's efforts to maintain awk after he left Lucent.
+
+g...@github.com:onetrueawk/awk.git
+
+We also track the bsd-features branch. This is a branch that takes the
+traditional one true awk and adds features that the BSD projects have added
over
+the years that are useful, but not too over the top (like bit functions).
+
+The typical update cycle goes something like:
+
+(1) Create a work tree for the vendor/one-true-awk branch
+ % cd freebsd-main
+ % git worktree create ../ota vendor/one-true-awk
+(2) Update the onetrueawk github
+ % cd ../awk
+ % git pull --rebase
+ % git branch --show-current
+ bsd-features
+ % git show-ref HEAD
+ f9affa922c5e074990a999d486d4bc823590fd93 refs/remotes/origin/HEAD
+(3) Copy that to the vendor branch and push upstream
+ % rm -rf ../ota/* # trailing /* is important
+ % cp -a * ../ota
+ % cd ../ota
+ % git add *
+ % git commit -m"Import awk YYYYMMDD hash f9affa922c5e" # 12 places
+ % git commit --amend
+ <insert the relevant bits from the FIXES file>
+ % diff -ur ../awk .
+ # Sanity check to make sure it looks good. The vendor branch should
+ # contain the unaltered sources from upstream since it's active
+ # again (for a while we were importing submitted patches to the
+ # vendor branch given the long lag with the old upstream, but no more)
+ % git tag -a -s vendor/one-true-awk/f9affa92 # 8 places
+ <enter gpg password>
+ % git push --follow-tags freebsd vendor/one-true-awk
+(4) Merge this into main
+ % git subtree merge -P contrib/one-true-awk vendor/one-true-awk
+ # resolve any conflicts and commit
+ # Be sure to use the same or similar commit message as you did for
+ # the import. If you import multiple versions before merging to head
+ # you may need to combine the messages. Also, if there's more than
+ # a screen of changes, you may want to abstract them down into an
+ # easy to digest summary.
+ % cd usr.bin/awk
+ % sudo make check
+ # make sure all the tests pass
+ % cd ../..
+ # awk is a build tool, so test the builds
+ % make buildworld / buildkernel for amd64, armv7, i386 and aarch64 (or
+ make universe/tinderbox if there's a lot of changes).
+ % git push freebsd
+(5) Oops, lost the race to push while testing, the following will rebase things
+ % git fetch freebsd
+ % git rebase --rebase-merges -i freebsd/main
