Daniel Rosenberg d9a520c5bd Add support for different F2FS block sizes 
F2FS has been expanded to allow for different block sizes. Currently the
block size must be the same as page size, but this may change in the
future. This gives support for 16K while not restricting the ability to
choose a block size that isn't based on the page size later on.

Bug: 279820706
Test: Boot 16k F2FS device

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For an outdated reference on Android.mk files, see build-system.html.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