In non-A/B OTA path, we've been loading the info dict for the target build twice (once to have a peek at the OTA type, with a reload after unzipping the target-files zip). Remove the reloading. This CL moves the loading of the source info dict up a bit to avoid having two copies in the A/B and non-A/B paths. It also moves up the sanity checks of the loaded info dicts before unzipping the target-files zips. Test: Generate full and incremental packages for bullhead and marlin.

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For an outdated reference on Android.mk files, see build-system.html.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