From 62e0bc7586077b3bde82759fb34b51b982cea20f Mon Sep 17 00:00:00 2001

Subject: Verify the package compatibility with libvintf.

verify_package_compatibility() is added to parse the compatibility entry
(compatibility.zip) in a given OTA package. If entry is present, the
information is sent to libvintf to check the compatibility.

This CL doesn't actually call libvintf, since the API there is not
available yet.

Bug: 36597505
Test: Doesn't break the install with existing packages (i.e. w/o the
      compatibility entry).
Test: recovery_component_test
Change-Id: I3903ffa5f6ba33a5c0d761602ade6290c6752596
