releasetools: do not remove dynamic partitions in system-only builds 
* Before this commit, the generated `dynamic_partitions_op_list` in
  FullOTA packages always tries to remove all partitions and recreate
  them upon flashing. This makes it impossible to have a system-only
  "FullOTA" because vendor partition(s) are always removed.

* This commit detects if a build is vendor-less and disables every
  dynamic partition operation except `resize`, in order to keep the
  original content around after the flash. The change should not affect
  non-dynamic-partition or builds with vendor image included.

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For an outdated reference on Android.mk files, see build-system.html.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.
