[EXPORT][NUCLEO_F334R8] export to gcc_arm and coide

- rtos library is not working because of double defined SysTick_Handler
in system_stm32f3xx.c and in rtos
- please see pullrequest #526 for a correct export
- tests are working fine:

Result: 17 OK

Completed in 125.02 sec
[EXPORT][NUCLEO_F334R8] a missing line in export/coide.py
[EXPORT][NUCLEO_F334R8] removed accidentally 2 macros

The commit 'export to gcc_arm and coide' removed accidentally 2 macros
from NRF51822 and NRF51 targets.
[DISCO_F429ZI] missing interrupt vectors

Added some missing F429 interrupt vectors
[K64F] Add mbed_mac_address implementation
[DISCO_F429ZZI] pin function definition

Added mostly all pin function (ADC, I2C, SPI, UART, PWM).

The basis of the target was DISCO_F407. The 429 has some additional pin
functions which are added with this commit. Also ports, pins and pin
functions of the larger packages are added not only the available of the
F429ZI package.
[DISCO_F429ZI] changed mcu names

Changed mcu names in comments from original F407 ot F429.
Export: IAR ewp template - add suffix lpc1768

	- ewp file does define target, and it's set to lpc1768
Export: IAR - sources in the project file, 3 targets ewp templates
[API] Timer-start behavior (bug)fix

Only start the timer when it is not running currently. In old behavior
the current slice-time was discarded, now multiple starts have no
effect.
[net][k64f] Add access to link status in emac driver
[DISCO_F429ZI] added a description why there are commented pwm config lines

Some text to explain the commented pwm pin config. Remove some Timer5
based pwm config.

The Timer5 lines are not allowed as pwm configs because the timer is
used by the us_ticker as mentioned at the start of the block. I've
overseen to remove these lines.
[README.md] rendering problem because of a missing new line

After last addition of a target, a new line was missing and that's why
there was a redering problem with a header line (Supported Toolchains
and IDEs).
Add BSD license to NVIC_SetVector and NVIC_GetVector.
[export] Add no rtti flag to exporters
[README.md] corrected the toolchains for IDEs CoIDE and emBlocks
