Format Go with gofmt, then golines -m 77 (closes #215)

script/fmt now runs golines -m 77 after gofmt, repeating golines until
it changes nothing, since one pass can leave a line the next splits.
script/fmt-check fails when either would change a file.
script/bootstrap installs golines v0.13.0 with go install, pinned to
its commit, and checks the installed version with go version -m.

The tree is reformatted. The longer lines this makes are fixed by
hand: nolint directives moved onto their own line above the statement,
one string split, and 20 functions over funlen's 80 lines shortened or
split, RunWAF and limitPercentages among them.
