AI 147118: Several fixes to reduce failing tests in the cts host

  - Removing tests that are placed in a protected package name.
  They were not part of the cts tests.
  - Fixing a case of an Exception thrown in the static initializer of
  GBCharsetEncoderTest.
  - Remove copy/paste code which led to an exception in a 2nd thread
  (the test did not fail, but its output was reported in logcat)
  - fixing a test case in FileTest
  - removing test code in StmtTest that tested badly specified operations and
  failed.
