[svn-r12774] Modified flush code in the metadata cache to allow it to
handle flush callbacks which can dirty other entries, and
resize and/or rename the target entry.
This feature is needed by the fractal heap code.
Also added associated test code.
H5Commit tested. Test failed on heping, but the
error appears to be a syntax error in an un-related
file.
Tests on copper & sol passed, along with tests on
phoenix.
