The current binder implementation is inflexible when it comes to adding new input/output parameters. It also needs a lot of boilerplate code written when adding a simple enable/disable type command. Instead, let clients specify the parcels they want to pass and unparcel them at the end points only. Please note that it is assumed that all commands coming in need the same permission checks. If this is no longer the case, some commands need to be split out on the receiver end in IQService.cpp. This change also simplifies the code end clients need to write. They should be able to include QServiceUtils and call a single function to set the binder up and make the call. Change-Id: I4db66f2427ecf16d7a6264462ae85815217a16b1
