Fix ProviderTree copying with threading Lock

Browse Source 
The threading Lock object cannot be copied so the ProviderTree cannot be
deep copied in threading mode. This patch adds custom pickling /
copying handlers to the ProviderTree class to ignore the lock from the
source and readd it in the destination object during pickling /
copying.

Note that ProviderTree uses a named lock which means all the instance of
the ProviderTree object in the same process uses a shared lock object.
The copy handlers ensures the same behavior during copying so the copy
will use the same shared lock as well.
