roomservice: Add lightweight dependencies to repositories

Roomservice can already fetch your cm_<device> without the need for a
manifest entry.

However, when working with common repositories, there is no way of
actually fetching them without adding to the manifest. This patch
introduces a lightweight dependency system. Each repository can have a
cm.dependencies in the following json format:

[
  {
    "repository": "repository_name_on_cm_organization"
    "target_path": "target/path"
  },
  ...
]

For instance, for cm_anzu I need android_device_semc_msm7x30-common and
android_device_semc_mogami-common. I would add both to cm.dependencies
as follows:

[
  {
    "repository": "android_device_semc_msm7x30-common",
    "target_path": "device/semc/msm7x30-common"
  },
  {
    "repository": "android_device_semc_mogami-common",
    "target_path": "device/semc/mogami-common"
  }
]

Roomservice would then fetch the anzu repository, parse the dependency
files and add/fetch/sync these additional repositories if they don't
exist already.

This also adds pretty printing to the output xml.

roomservice: Extend dependency-checks to devices in main manifest

so take that into account as well when checking device paths

roomservice: dont auto fetch deps

since we will only be using roomservice to fetch kernel repos in is
not a good idea to run it with lunch, instead add find_deps to manually
fetch the kernel repo for selected device

(squashed) cm inline kernel building

This is a combination of 7 commits.
The first commit's message is:
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

Darwin/OSX build host does not have module-init-tools which is
required to generated modules.dep file. Switch to modules.order
file marker which is always generated instead.

This is the 6th commit message:

kernel: allow TARGET_KERNEL_MODULES to overwrite kernel modules

This is necessary to use compat-wireless since it needs to build a newer
version of cfg80211 (and sometimes mac80211) than the kernel sources version.
There are probably other instances of this type of need.

kernel: use prebuilt by defalult

to build the kernel inline specifiy BUILD_KERNEL=true on the
command line. since the source is not automatically synced we let it
fallback to prebuilt even if BUILD_KERNEL is defined when the source
dir is not present.
to sync the source run find_deps after setting environment with envsetup.sh
