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.

For a peer outside `SWRP_TRUSTED_PROXIES`, `rproxy` now reads each header name with `_` as `-` and in any letter case, and removes the header when that name starts with `X-Forwarded-` or is `Forwarded` or `X-Real-IP`. Before, `X_Forwarded_Ssl: on` or `X_Real_IP` from a client connecting directly reached the app unchanged, and an app behind CGI or FastCGI reads them as the dash-spelt headers. A trusted peer's headers pass on as before. `SPEC.md` says so.

For a peer outside `SWRP_TRUSTED_PROXIES`, `rproxy` now removes every header whose name starts with `X-Forwarded-`, in any letter case, before it sets `X-Forwarded-For`, `X-Forwarded-Host` and `X-Forwarded-Proto`; `Forwarded` and `X-Real-IP` are removed as before. Until now only traefik's names were removed, so a client connecting directly could send `X-Forwarded-Ssl: on` or `X-Forwarded-Scheme: https` and make an app take a plain request for a secure one. A trusted peer's headers pass on unchanged. `SPEC.md` says so.

The command is now `sww waf`, and the package is `internal/waf`. Types,
functions, files, tests, comments, docs, the Dockerfile, the runit
script, `script/`, compose examples, the log field `waf_line` and the
`X-From-Waf` test header follow. No behaviour changes, and no setting
changes name: rproxy already finds the waf through `SWRP_WAF_BACKEND`.
Done with one `sed -i` (Discriminator and DISCRIMINATOR to WAF,
discriminator to waf) over the files `git grep -i discriminator`
listed, as sneak allowed for this rename, then `git mv` for the
package and files. By hand afterwards: the header's spelling, which
the linter requires, and the padding after `waf` in `sww`'s usage
text.

`smallwebwaf rproxy` reads the first 64 KiB of each body, asks servewaf over
HTTP/1.1, and passes what servewaf allows to the app within its limits. Any
other answer goes to the visitor as servewaf gave it. SWRP_DEFAULT_DISPOSITION
decides only when servewaf cannot be connected to, does not answer at all, or
does not answer within SWRP_TIMEOUT_MS. A method SPEC.md does not list gets 405.
Duplication: internal/rproxy copies passing-on code from internal/proxy until
#172 removes the originals.
Rule suppressed: gosec G704 and G705; gosec at
internal/smallwebwaf/rproxy_test.go:431; tagliatelle at
internal/requestlog/requestlog.go:203; paralleltest on one test.
Judgement call: an answer over 1 MiB, or with a status below 200, gets 502.
Judgement call: every target not starting with one / gets 400.
