Bug 301471 – [WebKitGTK] apply-build-revision-to-files.py should support "Canonical-link"

• Status: RESOLVED
• Resolution: FIXED
• Component: WebKitGTK

[Sam Sneddon [:gsnedders]]

As part of bug 266028, we need to migrate everything to supporting actual git trailers.

The best approach is probably replacing the existing code with something similar to:

```
git log --format=%B -1 HEAD | \
  sed -e 's/Canonical link:/Canonical-link:/' | \
  git -c trailer.Canonical-link.key=Canonical-link -c trailer.Identifier.key=Identifier -c trailer.git-svn-id.key=git-svn-id interpret-trailers --parse --no-divider
```

We need to specify the trailer.xxx.key config options because:

> Existing trailers are extracted from the input message by looking for a group of one or more lines that (i) is all trailers, or (ii) contains at least one Git-generated or user-configured trailer and consists of at least 25% trailers.

And we have plenty of groups which aren't all trailers in WebKit.
