added option to build rpc library. closes #1426

Added extra includes for CPPUTEST library - in CppUTest library structure we only include from include/CppUTest and we do not use other functionality

Proper fix for Cortex-M/Cortex-A RTOS issue ...

Created two new labels (CORTEX_A and CORTEX_M) that can be used to differentiate
between Cortex-A and Cortex-M code in the build system.

[RZ/A1H] commit for build system changes ...

- add CA9 category to build.py
- add library for RTX-CA9
- add target definition for RZ/A1H
- change some test related settings for RZ/A1H
- add gcc options for CA9

Revert "[RZ/A1H] mbed-RZ first release" ...

This reverts commit b78ac75.

[RZ/A1H] mbed-RZ first release ...

including
- mbed cmsis  for RZ/A1H
- mbed hal    for RZ/A1H
 - GPIO, Timer, I2C, SPI, InterruptIn
- CA9 related files
- RTOS support files for RZ/A1H

FAT library will be now built to .a / .ar separate folder. New switch -f / --fat is introduced for build.py script

Added support for cpputest library. UT libray now compiles as separate lib, just like other libs. For example ETH or RTX. Added support for cpputest sources in root of mbed project (on the same level with mbed sdk repo). changes include adding new paths to the project. Two example UT (UT_1, UT_2 are added). New option -O is introduced to force 'test build only'

spaces removal - workspace tools (not tmpl)

Updated DSP library + build system changes ...

Updated CMSIS DSP to latest version (CMSIS-SP-00300-r3p2-00rel1.zip)
Build system changes to be able to preprocess assembler sources before compiling them:

- GCC: use gcc '-x assembler-with-cpp'
- ARM: preprocess first, then assemble (two separate commands)
- IAR: added macro definitions and include directories to the assembler command line

Removed CORTEX_ARM_SUPPORT restriction for the DSP libraries.
Tested: LPC1768 with ARM, GCC_ARM and IAR, LPC11U24 with ARM.

Added CellularModem library, removed old VodafoneUSBModem library

Add script to export mbed SDK tests to different IDEs

Compile network and RTOS with GCC_ARM

Add license to workspace_tools files

Refactoring of the mbed SDK: ...

- Provide a well defined HAL and API
- Keep separated the HAL implementations for the different targets

Add scripts to sinchronize mbed.org libraries with mbed SDK

Avoid relying on environmental variables for ARMCC system include and library paths. Provide build progress notification to web IDE. Add generic MBED_MCU target.

Refactor the build system to keep the information about a new target in a single class

Add Freescale KL25Z

Initial commit of the mbed libraries and tools
