[PATCH v2 14/36] Use odb.origin.partialclonefilter instead of core.partialclonefilter

[Christian Couder <christian.couder@gmail.com>]

Let's make the partial clone filter specific to one odb
instead of general to all the odbs.

This makes it possible to have different partial clone
filters for different odbs.
