Build android.inputmethodservice Unit Tests and Integrate them in LAVA

Notes:
[2012/4/4 pfefferz]Take a look at, https://blueprints.launchpad.net/linaro-android/+spec/android.net-testing for an example.
[2012/4/18 kejun-zhou] /system/bin/ime is the input method services test tool.]
[2012/4/24 kejun-zhou] the lava test is available by using "bzr branch lp:~kejun-zhou/lava-android-test/ime".
[2012/4/30 pfefferz] Gonna shift this to 12.05 since all the builds didn't run it via, LAVA_TEST_PLAN="busybox,0xbench,glmark2,skia,v8,mmtest,cts,monkey" adding a specific note.
[2012/5/09 kejun-zhou] The test case is rejected by LAVA team. The reason is that the request of the BP is not clear.
[2012/5/21 pfefferz] Still pending LAVA merge.
[2012/5/24 asac] LAVA merge proposal has real comments to improve. they don't question the BP from what I see in comments.
[2012/7/21] please get off from backlog; it's implemented. you should set a goal/target milestone for all blueprints that are being worked on :).
