Change subject: Add support for NuRAN Wireless Litecell 1.5 BTS ......................................................................

Add support for NuRAN Wireless Litecell 1.5 BTS

Layer 1 compatibility with previous generation or NuRan GSM product, therefore the support for the Litecell 1.5 uses its own sources instead of using tons of ifdef/endif.

Max's amendments: * make headers path configurable * use configured TRX instead of hardcoded value * split subdir-objects into separate commit * cosmetic changes
