There were numerous small issues with test cases:
- some lacked the right source file header
- some were not portable at all
- some were using internal libzmq APIs (headers)
Solution: fixed and cleaned up.
Of course people still "can" distributed the sources under the
LGPLv3. However we provide COPYING.LESSER with additional grants.
Solution: specify these grants in the header of each source file.
- used msleep (10) in most places instead of zmq_sleep (1)
- may cause failures on slower machines
- to change, modify SETTLE_TIME in testutil.h
- tested down to 1 msec on fast boxes
