gn-build: Add BUILD files for libchrome 

This CL adds GN build files for libchrome, which is the ChromeOS/Brillo library
for many C++ tools, include libbase. I added a new GN build target for "base"
under secondary sources with a GN build file for libchrome which currently lives
in platform/external/libchrome in AOSP.

To build, clone libchrome into third_party/libchrome and remove
third_party/libchrome/base/BUILD.gn. Also clone external/modp_b64 into
third_party/modp_b64. Eventually I will have scripts set up to do
this automatically.

This means that we can start developing against libbase while running GN builds
on Goobuntu but this would break the tree until libchrome is buildable within
the Android build system (http://r.android.com/158392). So Brillo/Android builds
will depend on libchrome using the conventional Android.mk means.

Building with GN+ninja

======================



packages/modules/Bluetooth/system is buildable using the GN and and ninja buildtools from the Chromium

project. After setting up these tools, several third_party packages need to be

set up to build the stack. It's a simple matter of copying (or sym-linking) some

packages out of AOSP into "packages/modules/Bluetooth/system/third_party":



From AOSP:

1. "platform/external/libevent" => third_party/libevent. The relevant

  headers here are "event.h" and "event-config.h". event-config.h from

  external/libevent is only compatible on Android; this means that you will need

  to generate a new one based on the current platform. Please follow the

  instructions in external/libevent/README.android for instructions on how to

  generate this file.

2. "platform/external/libchrome" => third_party/libchrome. After that, remove

the BUILD.gn file that's in libchrome/base. This is a legacy file that only

works inside the Chromium project and we're using our own from secondary build

sources.

3. "platform/external/modp_b64" => third_party/modp_b64

4. "platform/external/tinyxml2" => third_party/tinyxml2



From Chromium:

1. "src/testing/gtest" => third_party/gtest



You will also need a fresh checkout of platform/hardware/libhardware and

platform/system/core for some include dependencies.



BUILD.gn files for all of these packages have already been set up under

"packages/modules/Bluetooth/system/build/secondary/third_party" (note: we don't have a BUILD.gn file for

modp_b64 since it comes with its own; as the package was imported into AOSP from

Chromium). To build, run:



1. 'gn args out/Default': This will prompt you to fill the contents of your

"args.gn" file. Set the two following variables:

  a. libhw_include_path=<path to your "platform/hardware/libhardware/include">

  b. core_include_path=<path to your "platform/system/core/include">



Once done, this will create the *.ninja files for the entire project.



2. 'ninja -C out/Default all': This will build all targets (the shared library,

executables, tests, etc) and put them in out/Default (or whatever you named the

output directory. To build an individual target, replace "all" with the target

of your choice, e.g. 'ninja -C out/Default net_test_osi'.
