Original commit message:
New driver for Prolific PL2303
A new driver for Prolific PL2303 devices, which is more or less a port
of the "pyprolific" driver from https://github.com/eblot/pyftdi
Demo now consists of two activities:
- DeviceListActivity shows all usb devices (including unsupported ones)
in a ListView.
- SerialConsoleActivity dumps the data stream for a device selected in
DeviceListActivity.
acquire() is renamed and deprecated in favor of findFirstDevice().
findAllDevices() is added as new functionality.
Internally, probe() now returns a list, allow a (future) multi-port
device to return multiple drivers, one for each port (googlecode
issue #14).
