revlog: support writing generaldelta revlogs

With generaldelta switched on, deltas are always computed against the first
parent when adding revisions. This is done regardless of what revision the
incoming bundle, if any, is deltaed against.

The exact delta building strategy is subject to change, but this will not
affect compatibility.

Generaldelta is switched off by default.
