Fix concurrency bug of GLProfile initialization ; Fix SharedResourceRunner 'dead' thread (Applets)

GLDrawableFactory:
  - clarify: public getWasSharedContextCreated(..) -> protected createSharedResource(..)
  - add: getSharesResourceThread()

GLProfile:
  - proper locking of initSingletion(..) path:
    - Use RecursiveThreadGroupLock and add/remove GLDrawableFactory's sharesResourceThread
      while creating it's the sharedResource.
      This simplifies and fixes GLProfile's locking code.

  - Fix and simplify initSingleton(boolean) API doc - mark it deprecated.

  - Add initSingleton() for controlled initialization only, pairing w/ shutdown(..)

Remove initSingleton(boolean) calls in code and test!

Fix SharedResourceRunner 'dead' thread (Applets)
  In Applets, stopping an Applet makes the browser Java plugin interrupting
  and killing all related threads, including our SharedResourceRunner thread.

  - Validate whether the shared resource thread is alive

  - Catch interruption in shared resource thread and assume it's a kill signal

  - releaseSharedResource: clear devicesTried set
