bundle2: add some distinction between mandatory and advisory part
Mandatory part cannot be ignored when unknown. We raise a simple KeyError
exception when this happen.
This is very early version of this logic, see inline comment for future
improvement lead.
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).
