J-Link Unsupported firmware version check

OpenOCD does not work with the latest firmware versions
of Segger J-Link.

Latest working version: V4.42c
Unsupported versions: 4.44 to 4.46f, 4.20 to 4.30

Older versions of firmware can be found here:
  http://www.segger.com/j-link-older-versions.html

The firmware versions does not correspond directly with
"Software and documentation pack for Windows", it may be
distinguished by the "compile" date in the information string.

Print an warning message if unsupported firmware version detected.
