Add "non-interactive" mode for the OTASP (CDMA provisioning) call.

Non-voice-capable devices (like Stingray) have no built-in phone UI, but
do still need to make a special phone call when first "activating" the
device.

Till now, the code handling the OTASP call (OtaUtils.java) was very
tightly coupled to the InCallScreen, using special modes of the in-call UI
to display the "skip" and "activate" choices, and display a DTMF dialpad
and Speaker button and progress info during the call.

This change decouples the OtaUtils and InCallScreen code, and allows the
OTASP call to run in "non-interactive" mode.  Now, on data-only devices we
launch the OTASP call without involving the InCallScreen at all.

This change also cleans up the way we send results back to the
SetupWizard:

  - First of all, in non-interactive mode, we now return an activity result
    right away after kicking off the OTASP call.  This lets our caller know
    either that the OTASP call started (and is running in the background),
    or that that we couldn't start the OTASP call at all.

  - And as before, when the OTASP call ultimately finishes, we send back a
    PendingIntent that was originally provided by our caller.  But now, we
    explicitly add an extra called EXTRA_OTASP_RESULT_CODE to that
    PendingIntent.  That extra's value is an integer code, which allows
    the caller to distinguish among several possible outcomes, namely
    "success", "failure", and "user skipped".

Finally, this change includes a test activity called OtaspTestActivity which
exercises the whole "non-interactive" OTASP sequence (which basically
mimics the PERFORM_CDMA_PROVISIONING behavior of SetupWizard.)

More details:

  - When we handle the PERFORM_CDMA_PROVISIONING intent (see
    InCallScreenShowActivation.java) we check a config resource called
    R.bool.voice_capable to decide whether to use the in-call UI.  (That
    resource is true by default, but overridden to false on Stingray.)

  - The singleton OtaUtils instance is now owned by the PhoneApp, not the
    InCallScreen, since we can now have an OtaUtils instance *without* an
    InCallScreen.

  - I renamed the "com.android.phone.InCallScreen.SHOW_ACTIVATION" intent
    action to be "com.android.phone.PERFORM_CDMA_PROVISIONING", to be more
    precise, and especially to make it clear that it's not tied to the
    InCallScreen.

  - Moved all OTASP-releated string constants into OtaUtils (rather than
    having them sprinkled around in 3 or 4 places.)
