[svn-r30084] First pass at the evict-on-close feature.

The features is controlled via H5Pset/get_evict_on_close()
and is currently enabled by default (it will be disabled
by default in the final implementation).

There is a bug in the code where the eviction of tagged
metadata fails due to some of the metadata being dirty,
resulting in error return values and test failures.
