Berkus Decker 2a8dc7eb33 Maintain size assumptions held by openocd (and probably JLink tools) 
* Buffer sizes are not prescribed exactly in Segger's implementation,
  but reference is made to "int" being 32 bits.
* 24 bytes size assumption is hardcoded in openocd RTT implementation.

Berkus Decker 1ba6c3f4d7 Add JLink RTT feature 
* SEGGER J-Link RTT allows to do terminal I/O without any additional
  connection except the J-Link itself.
