Initial move of code from frameworks/support/multidex to here

Also,
- Removed extraneous Eclipse-specific configuration files that are
  unnecessary in the Android build tree
- Includes the patch to support API level 19 from
  https://googleplex-android-review.git.corp.google.com/#/c/348129
- Checks for null and returns without patching the classloader when
  getting the package manager or package name from the passed in Context
  to MultiDex.install(...) since the Context object is probably a mock
  context for testing.
- Moved the test runners to package com.android.test.runner, which seems
  to be the standard place for all test runners.
