Reland: Rework platform version to hide codenames.
The public platform version no longer can be a codename, it is
always the most recently released platform. A new build property
and API provides either the offical version or the current codename
as appropriate. This will avoid breaking apps that look at the
platform version while development is under a codename.
Changes from the original version:
- Logic for emitting system properties has also been added to
buildinfo_common.sh to make sure that ro.${partition}.build.*
are consistent with ro.build.*.
- We also use PLATFORM_VERSION_LAST_STABLE as the value set in the
boot image os_version header / hash tree additional headers to
ensure they match with the ro.build.version.release system property.
This is hopefully a temporary workaround while we stop using the
system property for this purpose.

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For an outdated reference on Android.mk files, see build-system.html.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