[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
