Additional appendfile fixes for interleaved data/index files

The appendfile code was not passing default version info to the
changelog or manifest classes, and so they were always being created
as version 0.

revlog.checkinlinesize had to be corrected to seek to the end
of the index file when no index file was passed (only clone does this)
