188a478214 #5417 
strict inequality (over reals) require solving for least-upper/greatest-lower bounds that may coincide with non-strict inequalities (be epsilon stronger). Instead of using the coefficient 'a' to turn the inequality into an equality, add the slack value as a constant.

e844aef896 remove a few more copy constructors, though still not enough to enable the assertion in vector 
I give up for now; there are too many copies left for little return..

baa96909cc mb-skolem for arithmetic with model repair 
The contract is that users of mb-skolem ensure that
interface equalities are preserved (by adding a
sufficient set of disequalities, such as a chain
x1 < x2 < x3 .., to force that solutions for
x_i does not clash).

4b517b96df [CMake] Move CMake files into their intended location so the 
`contrib/cmake/bootstrap.py` script no longer needs to be executed.

The previous location of the CMake files was a compromise proposed
by @agurfinkel in #461. While this has served us well (allowing progress
to be made) over time limitations of this approach have appeared.

The main problem is that doing many git operations (e.g. pull, rebase)
means the CMake files don't get updated unless the user remembers to
run the script. This can lead to broken and confusing build system
behaviour.

This commit only does the file moving and necessary changes to
`.gitignore`. Other changes will be done in subsequent commits.
