[svn-r17399] Description:
Bring r17393 and r17398 from trunk to 1.8 branch: Bring back more changes from the file free space branch to the trunk. (17393) First set of changes to move VFD 'truncate' call out of H5F_flush and defer it until the file is closed. (17398) Tested on: FreeBSD/32 6.3 (duty) in debug mode (h5committested on trunk)
