Fix merge 64545a8ced5aa350e917ab1824a1c06a14a96532

    Make vCard code a separated static library.

    - Move the library to a separate directory in framewokr/base, and rename its package from
      android.pim.vcard to com.android.vcard.
    - Move all tests for the library under the directory.
    - Confirm all tests for vCard are successful.

    It would be better for us to have this directory somewhere else (like external/).
    But I'll submit this here now and move it to the right place as soon as possible.
    From the view of build mechanism, we can do that immediately.
