[svn-r8865] Purpose:
Code optimization
Description:
Re-work the insertion of a new child into an existing node, to exploit
some speedups for adding the rightmost child, since this is a very common case
when appending records to an unlimited size dataset.
Also, hoist the checks for the tree's 'K' value into a field in the shared
information about the tree, instead of re-calculating them all the time.
Platforms tested:
Solaris 2.7 (arabica)
FreeBSD 4.10 (sleipnir) w/parallel
Too minor to require h5committest
