Remarks
Do a quick check for whether an application might be able to perform an operation. This is <em>not</em> a security check; you must use #noteOp(String, int, String, String, String) or #startOp(String, int, String, String, String) for your actual security checks, which also ensure that the given uid and package name are consistent. This function can just be used for a quick check to see if an operation has been disabled for the application, as an early reject of some work. This does not modify the time stamp or other data about the operation.
Important things this will not do (which you need to ultimate use #noteOp(String, int, String, String, String) or #startOp(String, int, String, String, String) to cover):
<ul> <li>Verifying the uid and package are consistent, so callers can't spoof their identity.</li> <li>Taking into account the current foreground/background state of the app; apps whose mode varies by this state will always be reported as #MODE_ALLOWED.</li> </ul>
