Tests only, in `internal/sww`. Every wait for the `starting` line now uses `output.lineBeforeExit`, which waits until the line is written or sww exits, so a slow Core Rule Set compile on a loaded host no longer fails these tests. `TestMainRunsWAF` and `startRProxyProcess` start sww through `startProcess`, whose cleanup kills sww as the test ends and waits for it to exit; `startRProxyProcess` returns a stop function that sends SIGTERM and fails the test unless sww exits with status 0 within `waitLimit`.

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.
