[svn-r10184] Purpose:

    New feature

Description:
    Add new "block tracker" data structure to library, for tracking blocks of
bytes in a file.  Block trackers will be used to keep track of the blocks
belonging to the soon-to-be-implemented "segmented heap" which is designed to
replace the current local & global heaps (starting with the local heap).
Block trackers will also keep track of the free space in the segmented heap
and someday could be used to track the free space in the entire HDF5 file.
    They are implemented as a small header of information to cache the state
of the blocks (max & min sizes of blocks tracked, etc.) and the records of
the blocks themselves are stored in a v2 B-tree.

Platforms tested:
    FreeBSD 4.11 (sleipnir)
    Solaris 2.9 (shanti)
