shelve: directly handle the initial parent alignment
Shelve is currently sub-contracting some of its work to the rebase extension.
In order to make shelve more independent and flexible we would like shelve to
handle the parent alignment directly.
After this change, we no longer need to use rebase in shelve.

562 the underlying revision storage object | |
563 | |
564 A revlog consists of two parts, an index and the revision data. | |
565 | |
566 The index is a file with a fixed record size containing | |
6912 | 567 information on each revision, including its nodeid (hash), the |
1083 | 568 nodeids of its parents, the position and offset of its data within |
569 the data file, and the revision it's based on. Finally, each entry | |
570 contains a linkrev entry that can serve as a pointer to external | |
571 data. | |
572 | |
573 The revision data itself is a linear collection of data chunks. | |
574 Each chunk represents a revision and is usually represented as a | |
575 delta against the previous chunk. To bound lookup time, runs of | |
576 deltas are limited to about 2 times the length of the original | |
577 version data. This makes retrieval of a version proportional to | |
578 its size, or O(1) relative to the number of revisions. | |
579 | |
580 Both pieces of the revlog are written to in an append-only | |
581 fashion, which means we never need to rewrite a file to insert or | |
582 remove data, and can use some simple techniques to avoid the need | |
583 for locking while reading. | |
