repoview: have unfilteredpropertycache using the underlying cache
A `unfilteredpropertycache` is a kind of `propertycache` used on `localrepo` to
unsure it will always be run against unfiltered repo and stored only once.
As the cached value is never stored in the repoview instance, the descriptor
will always be called. Before this patch such calls always result in a call to
the `__get__` method of the `propertycache` on the unfiltered repo. That was
recomputing a new value on every access through a repoview.
We can't prevent the repoview's `unfilteredpropertycache` to get called on every
access. In that case the new code makes a standard attribute access to the
property. If a value is cached it will be used.
The `propertycache` test file have been augmented with test about this issue.

These will fail (using --source):
G onto F - rebase onto an ancestor:
$ hg clone -q -u . a a7

$ hg rebase -s 6 -d 5
nothing to rebase
[1]
F onto G - rebase onto a descendant:
$ hg rebase -s 5 -d 6
abort: source is ancestor of destination
[255]
G onto B - merge revision with both parents not in ancestors of target:
$ hg rebase -s 6 -d 1
abort: cannot use revision 6 as base, result would have 3 parents
[255]
These will abort gracefully (using --base):
G onto G - rebase onto same changeset:
$ hg rebase -b 6 -d 6

G onto F - rebase onto an ancestor:
$ hg rebase -b 6 -d 5

More advanced tests
rebase on ancestor with revset
$ hg clone -q -u . ah ah5
$ cd ah5
$ hg rebase -r '6::' -d 2

rebase with multiple root.
We rebase E and G on B
We would expect heads are I, F if it was supported
$ hg clone -q -u . ah ah6
$ cd ah6
$ hg rebase -r '(4+6)::' -d 1
saved backup bundle to $TESTTMP/ah6/.hg/strip-backup/3d8a618087a7-backup.hg (glob)

o | 1: 'B'

$ cd ..
More complex rebase with multiple roots
each root have a different common ancestor with the destination and this is a detach
(setup)
$ hg clone -q -u . a a8
$ cd a8
$ echo I > I
$ hg add I
$ hg commit -m I
$ hg up 4
1 files updated, 0 files merged, 3 files removed, 0 files unresolved
$ echo I > J
$ hg add J
$ hg commit -m J
created new head
$ echo I > K
$ hg add K
$ hg commit -m K
