Enable checkstyle rule to catch variables that hide fields

Enable the checkstyle "HiddenFields" rule and fix any issues
that it detects.  Suppress these violations for parameters
to setters and constructors.

Added support for the checkstyle comment suppression module
// CHECKSTYLE:OFF and //CHECKSTYLE:ON are now
supported.

Suppressed HiddenField checks for net.onrc.onos.core.packet.*
rather than fix them.  These APIs are designed to
require formal parameters and local members having
the same name.
