[svn-r17894] Description:

	Bring r17893 from trunk to 1.8 branch:

	Remove old shim H5B2 routines from refactoring, rename new routines to
old routine names and switch all users of the H5B2 interface back to the old
routine names now that the switch to using the more current open -> <operation>
-> pattern is used for all the H5B2 code.  This is the final change before 
adding a context to the H5B2 client encode/decode callbacks.

Tested on:
       FreeBSD/32 6.3 (duty) in debug mode
	(h5committested on trunk)
