    Add otapackage support for backuptool

    Change-Id: I512554c579d444067cd3ccbb0e6946a5eb6bc964a

    Modular backuptool.sh.  Executes backup and restore methods defined in arbitrary /system/addon.d/*.sh scripts.

    * Copy backuptool.functions alongside backuptool.sh.
    * Delete both from /system/bin as they are not useful there.

    update ota_from_target_files to handle mounting/unmounting for backupscript

    backupscript should not be mounting/unmounting itself as it makes other
    scripts have unexpected results (such as modelid_cfg, which expects /system
    to be mounted)

    instead have the ota script handle the mounting/unmounting

    build: Disable backuptool on user instead of GMS builds

    * Backuptool is not exclusively used for GApps but
      also used by other things (i.e. Magisk), hence
      it shouldn't be disabled on all GMS builds.

Android Make Build System

This is the Makefile-based portion of the Android Build System.

For documentation on how to run a build, see Usage.txt

For a list of behavioral changes useful for Android.mk writers see Changes.md

For an outdated reference on Android.mk files, see build-system.html. Our Android.mk files look similar, but are entirely different from the Android.mk files used by the NDK build system. When searching for documentation elsewhere, ensure that it is for the platform build system -- most are not.

This Makefile-based system is in the process of being replaced with Soong, a new build system written in Go. During the transition, all of these makefiles are read by Kati, and generate a ninja file instead of being executed directly. That's combined with a ninja file read by Soong so that the build graph of the two systems can be combined and run as one.
