initial import

The original osmo-gsm-tester was an internal development at sysmocom, mostly by
D. Laszlo Sitzer <dlsitzer@sysmocom.de>, of which this public osmo-gsm-tester
is a refactoring / rewrite.

This imports an early state of the refactoring and is not functional yet. Bits
from the earlier osmo-gsm-tester will be added as needed. The earlier commit
history is not imported.
