Currently CreateRadio only allows a single outstanding DBus message until the radio is fully created. 99% of the time this is just fine but in order to test dual phy cards there needs to be support for phy's appearing at the same time. This required storing the pending DBus message inside the radio object rather than a single static variable. The code was refactored to handle the internal radio info objects better for the various cases: - Creation from CreateRadio() - Radio already existed before hwsim started, or created externally - Existing radio changed name, address, etc. First, Name is now a required option to CreateRadio(). This allows the radio info to be pushed to the queue immediately (also allowing the pending DBus message to be tracked). Then, when the NEW_RADIO event fires the pending radio can be looked up (by name) and filled with the remaining info. If the radio was not found by name but a matching ID was found this is the 'changed' case and the radio is re-initialized with the changed values. If neither name or ID matches the radio was created externally, or prior to hwsim starting. A radio info object is created at this time and initialized. The ID was changed to a signed integer in order to initialize it to an invalid number -1. Doing this was required since a pending uninitalized radio ID (0) could match an existing radio ID. This required some bounds checks in case the kernels counter reaches an extremely high value. This isn't likely to ever happen in practice.
