b5aa6d5eb5 Fix issue with bd1f07f864 pointed out by 
@nunolopes .

If `pthread_cond_signal()` is called while `m_mutex` is held then the
timing thread might be woken up twice due to waking up from
`pthread_cond_timeout()` (due to being signaled) but then being forced
to sleep again because the thread calling `~imp()` is still holding
`m_mutex` (which the timing thread needs to acquire).

2e74a2c54e Refactor update_api.mk_ml() so that the source and output directories 
can be different. This feature will be needed by the CMake build system
to build the OCaml bindings.

76bbecf4fe Refactor mk_z3consts_ml() code into mk_z3consts_ml_internal() 
and move that into `mk_genfile_common.py`. Then adapt `mk_util.py` and
`mk_consts_files.py` to call into the code at its new location.

The purpose of this change is to have Python code common to the Python
and CMake build systems separate from Python code that is only used for
the Python build system.

0e03fe9bf2 Fix inconsistent emission of OCaml enumeration files. The ordering of emitted 
enum values is not consistent between python 2 or 3. The root cause
of the problem was a dictionary's keys being iterated over which has
no defined order.

This has been fixed by iterating over the dictionary's items and
ordering by values.  We could order by key rather than the values but
seeing as these represent an enum, ordering by value makes more sense.

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 .
