e85f9d33c4 add "legacy" support for theory case splits 
this replicates what was done in theory_str to add axioms excluding each
pair of literals from being assigned True at the same time;
no new heuristics are being used in smt_context (yet)

bd1f07f864 Fix implementation of scoped_timer under Linux where it was 
incorrectly assumed that `pthread_cond_timedwait()` would exit
due to a condition variable being signaled or a timeout occuring.

According to the documentation `pthread_cond_timedwait()` might
spuriously wake so we introduce a new variable `m_signal_sent` (that is
guarded by an existing mutex) that is used as the variable to check that
the thread wake was not spurious.

This is intended to partially fix #839 .

e9411e5b8c explicitly re-introduce string axioms on refreshed string theory vars 
this fixes at least one case (kaluza/unsat/big/9650.smt2) where a string
could have a negative length value due to a constraint that went out of scope
