[svn-r22422] Purpose: Add support for SWMR with v2 b-trees
Description:
Adds SWMR support to the v2 b-trees when used as a chunk index. Because each
node keeps track of the total number of records reachable through each of its
children, nodes must be shadowed every time a descendent record is inserted or
removed. This implementation prevents this from happening, however, if the node
has already been shadowed since the last time the v2 b-tree header was flushed.
Also modified SWMR test to include v2 b-trees.
Tested: jam, koala, ostrich (h5committest), durandal
Note: There is a preexisting failure in the ph5diff (-v) test
