Initial porting to tizenrt-artik05x. Tizen RT is a lightweight RTOS-based platform to support low-end IoT devices. The project is under developing in github TizenRt repo. Artik05x is an IoT SoC solution that will be released soon. This PR contains the minimum porting that can print Hello world from jerryscript and a document for building and running. I used jerry_port.c and jerry_main.c in nuttx port and default port for porting base code. Also I used Make.defs and Makefile in working example in tizenrt for adding jerryscript configuration.

About
This folder contains files to build and run JerryScript on TizenRT with Artik05x board.
How to build
1. Set up build environment
- Install toolchain
Get the build in binaries and libraries, gcc-arm-none-eabi-4_9-2015q3-20150921-linux.tar.
Untar the gcc-arm-none-eabi-4_9-2015q3-20150921-linux.tar and export the path like
$ tar xvf gcc-arm-none-eabi-4_9-2015q3-20150921-linux.tar
$ export PATH=<Your Toolchain PATH>:$PATH
- Get the jerryscript and TizenRT sources
$ mkdir jerry-tizenrt
$ cd jerry-tizenrt
$ git clone https://github.com/jerryscript-project/jerryscript.git
$ git clone https://github.com/Samsung/TizenRT.git tizenrt
The following directory structure is created after these commands
jerry-tizenrt
├── jerryscript
└── tizenrt
2. Add jerryscript configuration for TizenRT
$ cp -r jerryscript/targets/tizenrt-artik05x/apps/jerryscript/ tizenrt/apps/system/
$ cp -r jerryscript/targets/tizenrt-artik05x/configs/jerryscript/ tizenrt/build/configs/sidk_s5jt200/
Apply following diff in jerry-tizenrt/tizenrt/os/FlatLibs.mk. (The line number may differ since tizenrt is under developing.)

# Export all libraries
3. Configure TizenRT
$ cd tizenrt/os/tools
$ ./configure.sh sidk_s5jt200/jerryscript
4. Build JerryScript for TizenRT
# assuming you are in jerry-tizenrt folder
$ cd jerryscript
$ make -f targets/tizenrt-artik05x/Makefile.tizenrt
5. Build TizenRT binary
# assuming you are in jerry-tizenrt folder
$ cd tizenrt/os
$ make
Binaries are available in tizenrt/build/output/bin
6. Flash binary
The official guide will be announced on TizenRT page.
7. Run JerryScript
You can use minicom for terminal program, or any other you may like, but set
baud rate to 115200.
(Note: Device path may differ like /dev/ttyUSB1.)
sudo minicom --device=/dev/ttyUSB0 --baud=115200
