prevent transient leaks of file handle by using new helper functions

These leaks may occur in environments that don't employ a reference
counting GC, i.e. PyPy.

This implies:
 - changing opener(...).read() calls to opener.read(...)
 - changing opener(...).write() calls to opener.write(...)
 - changing open(...).read(...) to util.readfile(...)
 - changing open(...).write(...) to util.writefile(...)
