[svn-r18704] Description:

	Bring r18702 from trunk to 1.8 branch:

	Bring r18672 from metadata journaling "merging" branch to trunk:

	Mostly changes to move to only using one 'user data' parameter for
calls to H5AC_protect(), along with some minor reformatting code cleanups.

Tested on:
       FreeBSD/32 6.3 (duty) in debug mode
       FreeBSD/64 6.3 (liberty) w/C++ & FORTRAN, in debug mode
       Linux/32 2.6 (jam) w/PGI compilers, w/default API=1.8.x,
               w/C++ & FORTRAN, w/threadsafe, in debug mode
       Linux/64-amd64 2.6 (amani) w/Intel compilers, w/default API=1.6.x,
               w/C++ & FORTRAN, in production mode
       Solaris/32 2.10 (linew) w/deprecated symbols disabled, w/C++ & FORTRAN,
               w/szip filter, in production mode
       Linux/64-ia64 2.6 (cobalt) w/Intel compilers, w/C++ & FORTRAN,
               in production mode
       Linux/64-amd64 2.6 (abe) w/parallel, w/FORTRAN, in production mode
       Mac OS X/32 10.6.3 (amazon) in debug mode
       Mac OS X/32 10.6.3 (amazon) w/C++ & FORTRAN, w/threadsafe,
               in production mode
