[svn-r18171] Description:

	Bring r18169 from 'merge_metadata_journaling' branch back to trunk:

	Converge changes on metadata_journaling branch and trunk:
		- Remove H5F_t* parameter from H5HL_unprotect()
		- Remove H5F_t* parameter from H5HL_dirty()
		- Remove H5F_t* parameter from H5O_unprotect()
		- Bring changes to metadata caching routines back:
		     - H5AC_pin_protected_entry()
		     - H5AC_resize_pinned_entry()
		     - H5AC_unpin_entry()
		     - H5AC_mark_pinned_entry_dirty()
		     - H5AC_mark_pinned_or_protected_entry_dirty()
		 - Revise internal H5C routines to drop H5F_t* and/or H5C_t* as
			parameter where possible
		 - Revise tests to follow internal routine changes

	Also, drop file/cache pointer parameter from create/destroy flush
dependency internal cache calls.

	Also, other minor changes to speedup the 'cache' test.
