subrepo: drop the 'ui' parameter to cat()

This no longer needs to be explicitly passed because the subrepo object tracks
a 'ui' reference since fcbc66b5da6a.  See the change to 'archive' for details
about the differences between the output level in the root repo and subrepo 'ui'
object.

The only use for 'ui' in cat is to emit a status message when a subrepo is
missing.  The bad() method on the matcher still uses the root repo's ui, because
narrowing the matcher doesn't change the ui object.

Check whether size of generaldelta revlog is not bigger than its
regular equivalent. Test would fail if generaldelta was naive
implementation of parentdelta: third manifest revision would be fully
inserted due to big distance from its paren revision (zero).

Verify rev reordering doesnt create invalid bundles (issue4462)
This requires a commit tree that when pulled will reorder manifest revs such
that the second manifest to create a file rev will be ordered before the first
manifest to create that file rev. We also need to do a partial pull to ensure
reordering happens. At the end we verify the linkrev points at the earliest
commit.
