build: Automatically replace old-style kernel header includes with new header lib

This is a combination of 3 commits.
This is the 1st commit message:

build: add kernel header dependency if module uses kernel headers

Many of the QCOM components use kernel headers, but don't declare
the dependency on them.  This is fine in CAF because of the way they
build the boot.img before anything else.  In CM, we don't build the
boot.img the same, so we run into a race between the kernel build &
these modules... and the modules lose.

Warn about modules that have this missing dependency, and add it for
them so we don't have to modify each Android.mk.

This is the commit message #2:

build: Switch kernel header inclusion

The build is switching to the target INSTALLED_KERNEL_HEADERS to
declare dependencies on kernel headers.

This is the commit message #3:

build: Automatically replace old-style kernel header includes with new header lib

Since we do this via soong and the result is a header library, just replace all
legacy include paths that point to the old header location with calls to the new
header library. Since we no longer have the legacy include, we can also remove
the additional dependency.

This reverts commit fa798218e5b7f96e12ab3acc9d47a3f26a140777.

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For an outdated reference on Android.mk files, see build-system.html.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