Allow the emulator launcher to take new options that are commonly
used:
* --window: shows the emulator window instead of running headless
* --avd: set the emulator name instead of using the env var, this
can be more intuitive and more expected than the env var.
* --help: to guide users how to use this script.
Also, the script now will print a list of available AVD names to
use instead of the less obvious error of no AVD name provided
which forces the user to manually find the names first.
This also, sets the COIN_CTEST_RESULTSDIR to CWD in case
it's not set, this is the case when running as a debug VM.
