AI 146184: am: CL 145976 am: CL 145806 Add qemud-version auto-detection logic to android/hw-qemud.c

Print "Press F6 to exit trackball mode..." in the window title bar when one
activates the persistent trackball mode. The actual text depends on your
key binding configuration.
Refine the skin directory auto-search paths when an AVD name is not given on the
command line. This makes the following work correctly:
tools/emulator -sysdir platforms/android-1.5/images -data foo.img
