debugbuilddag: build a changelog dag from a concise description

Useful in tests to quickly build a complex DAG in an empty repo.
Handles local tags and named branches.
Options to, at each rev,
 - create a new file,
 - overwrite the same file,
 - append to the same file,
 - write to a specific line in a mergeable file.
Can run shell commands during DAG buildup.

% directory moved and symlinked

% now addremove should remove old files
adding bar/a
adding foo
removing foo/a
