Host test plugins: added copy pligins, and removed Selenium and eACommander dependency from Test API

[NUCLEO_F411RE] Adapt python script + CMSIS files to build/export to IAR

Added parent directory to import path to host test script so we can now impoer workspace_tools.* as we do in other scripts - problem was host_test.py and other tests run with custom CWD and imports are not easy to maintain

Added copy + reset method for eACommander

Added simple commen to GOANNA_PATH. This will be refactored in the future to get more flexible Goanna settings in private_settings.py

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'

cppcheck Popen usage improvements (stderr issues)

Added CPPCHECK static analysis for MBED and CMSIS libraries from command line. Use switch --cppcheck

mbed-tools package improvements ...

- install all the needed components
- use a customized version of private_settings.py. Projects using mbed-tools
  will be able to use mbed_settings.py instead of private_settings.py. This
  ensures compatibility with the current structure.

Added on-line defined macros to the build system ...

Added 3 macros defined by the on-line build system to the off-line build
system: MBED_BUILD_TIMESTAMP, MBED_USERNAME and __MBED__.

Default to ARM GCC tools in the system path

Added default path for Goanna

Tidy up default settings

Compile network and RTOS with GCC_ARM

Add license to workspace_tools files

Reverted unnecessary change to settings.py ...

Also keeps the GCC_ARM_PATH in keeping with the rest of the code, rather than looking out of place.

Added ytsuboi's modifications for using the 1114

Add build options ...

Implement "save-asm" option

Update default CodeWarrior paths

Refactor the build system: ...

* add sets of TARGET and TOOLCHAIN "labels"

Use correct setting for -mfpu when building for Cortex-M4 targets, and ...
