[svn-r9537] Purpose:
Code cleanup & optimizations
Description:
Clean up some of the code in attributes to avoid allocating memory and
performing type conversions when the conversion is a noop.
Avoid memory allocations of attribute data structures by switching to use
library's free list memory allocator routines.
Avoid memory allocations of object header continuation data structures by
switching to use library's free list memory allocator routines.
Rearrange threaded, balanced binary tree macros slightly to avoid some
overhead.
Platforms tested:
FreeBSD 4.10 (sleipnir) w/parallel
Solaris 2.7 (arabica)
Too minor to require h5committest
