rebuildmeta: optimize by removing quadratic time usage
Calling ctx.children() for revision R visits all revisions greater than
R. If I remember my algorithmics right, that's O(n^2). Performing an
extra traversal, however, is O(n).
A quick benchmark on a repository ~20k revisions:
before: 445.27s user 1.10s system
after: 7.25s user 0.25s system
The resulting `svn' directories are exactly the same, and the tests
continue to pass.
