repoview: make propertycache.setcache compatible with repoview
Propertycache used standard attribute assignment. In the repoview case, this
assignment was forwarded to the unfiltered repo. This result in:
(1) unfiltered repo got a potentially wrong cache value,
(2) repoview never reused the cached value.
This patch replaces the standard attribute assignment by an assignment to
`objc.__dict__` which will bypass the `repoview.__setattr__`. This will not
affects other `propertycache` users and it is actually closer to the semantic we
need.
The interaction of `propertycache` and `repoview` are now tested in a python
test file.
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).
