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.

build: Inline kernel building as a buildtime task

Kernel image integration is now done in the build system. The
"one true way" of doing this is to download the kernel source
into kernel/TARGET_BOOTLOADER_NAME (by usage of the cm.dependencies
mechanism or otherwise), and defining the TARGET_KERNEL_CONFIG
variable in the device's BoardConfig makefile

If the kernel's location doesn't match the automagic location
(multi-device kernel source, for instance), TARGET_KERNEL_SOURCE
can be used to specify a kernel path (i.e.,
"TARGET_KERNEL_SOURCE := kernel/shared-whatever")

If the device requires out-of-kernel-tree modules to be built,
the TARGET_KERNEL_MODULES variable can be used, pointing to a
_make target_ that will build and install such modules. Definition
of such a target is the device author's responsibility, the only
restriction is that it is a normal makefile recipe (example
below)

Optionally (or as an alternative), a prebuilt binary can also be
defined at BoardConfig, by usage of the TARGET_PREBUILT_KERNEL
variable. This binary will be used if the kernel source is absent
(or undefined).

A minimal BoardConfig.mk should look something like this:

TARGET_KERNEL_CONFIG := cyanogenmod_<device>_defconfig
TARGET_PREBUILT_KERNEL := device/<vendor>/<device>/kernel

To include, for example, the TI WLAN modules, this can be used:

-----------------------------
TIWLAN_MODULES:
       make -C hardware/ti/wlan/wl1283/platforms/os/linux/ KERNEL_DIR=$(KERNEL_OUT) ARCH="arm" CROSS_COMPILE="arm-eabi-" TNETW=1273 RANDOM_MAC=n REPORT_LOG=n
       mv hardware/ti/wlan/wl1283/platforms/os/linux/tiwlan_drv.ko $(KERNEL_MODULES_OUT)
       make -C hardware/ti/wlan/wl1283_softAP/platforms/os/linux/ KERNEL_DIR=$(KERNEL_OUT) ARCH="arm" CROSS_COMPILE="arm-eabi-" TNETW=1273 REPORT_LOG=n
       mv hardware/ti/wlan/wl1283_softAP/platforms/os/linux/tiap_drv.ko $(KERNEL_MODULES_OUT)

TARGET_KERNEL_MODULES := TIWLAN_MODULES

kernel: allow TARGET_KERNEL_MODULES to overwrite kernel modules

This is necessary to use compat-wireless since it needs to build a newer

There are probably other instances of this type of need.

envsetup: set OUT_DIR to an absolute path always

OUT_DIR was set to $(TOPDIR)out previously,
but $(TOPDIR) was null, so it was a relative path.
This broke releasetools, inline kernel building, etc
since they require absolute paths.
Fix it so that it is set to $(shell readlink -f .)/out
if $(TOPDIR) is null.

Also remove hacks which checked if (OUT_DIR) was out
and changed it to $(ANDROID_BUILD_TOP)/out to workaround
the aforementioned problem.
