build: Squash of allowing a device to generically define its own headers

    Allow a device to generically define its own headers

    We have a few cases of devices including specific versions of projects
    just because of modified headers (msm_mdp.h comes to mind), and I just
    had enough of ifdeffing header files for specific cases (the P990 needs
    a lot of these).
    Now... if a target defines a TARGET_SPECIFIC_HEADER_PATH, any headers in
    there will take precedence over the standard ones; for example, on the
    p990, I have

    TARGET_SPECIFIC_HEADER_PATH := device/lge/p990/include

    which makes, for example, the
    device/lge/p990/include/hardware_legacy/AudioHardwareInterface.h be
    used instead of
    hardware/libhardware_legacy/include/hardware_legacy/AudioHardwareInterface.h
    whenever a source file uses <hardware_legacy/AudioHardwareInterface.h>

    build: fix target header overlay

    LOCAL_C_INCLUDES as defined by the makefile should be put AFTER
    the overlay includes so the overlay always takes precedence.

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For an outdated reference on Android.mk files, see build-system.html.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