4b0f2cae0d fix compiler warning in scoped_timer.cpp on linux 
2 secs in nanosec representation still fit in 31 bits, so no need for ULL

d9bafc3fba rewrite scoped_timer for linux 
The previous version was racy and could lead to crashes.
The timer could be deleted before the callback was called, making it execute on already freed memory

This new version is similar to Mac's. It spawns its own thread and uses pthread_cond_wait.
Care is taken for small timeouts to avoid races in the thread creation and timer destruction.

fc592fc856 fix for #291. The root issue is that the set of antecedents is recycled as a fixed object between routines. Antecedents that were already allocated for a Gomory cut got reset by the internalizer. This causes unsound bounds axioms to be created

Removing it ensures the function never returns null and enables further optimizations.
