[svn-r18602] Description:

    Bring r18600 from trunk to 1.8 branch:

    Increment reference count on object header when "fake" object header
chunk proxy is returned from H5O_chunk_protect().  Also, clean up the
interface to H5O_chunk_unprotect by removing the unnecessary 'oh' parameter.

Tested on:
    Mac OS X/32 10.6.3 (amazon) w/debug
    (h5committested on trunk)
