Miroslav Lichvar 78b9c13a11 sources: replace unreachable sources before selection 
The commit c43efccf02 ("sources: update source selection with
unreachable sources") caused a high rate of failures in the
148-replacement test (1 falseticker vs 2 unreachable sources). This was
due to a larger fraction of the replacement attempts being made for the
source incorrectly marked as a falseticker instead of the second
unreachable source and the random process needed more time to get to the
expected state with both unreachable sources replaced.

When updating reachability of an unreachable source, try to request the
replacement of the source before calling the source selection, where
other sources may be replaced, to better balance the different
replacement attempts.

README 

This is a collection of simulation tests using the clknetsim simulator
(supported on Linux only).

https://github.com/mlichvar/clknetsim

The CLKNETSIM_PATH environment variable should point to the directory where
clknetsim was downloaded and compiled. If the variable is not set, the tests
will look for clknetsim in ./clknetsim in the current directory.

The tests are written in bash and they can be run directly. The ./run script
runs all tests.
