34da0a32b9 [Z3py] Fix error in FPRef.__neg__() 
`FPRef.__neg__()` did not work previously because it tried to construct an FPRef from an FPRef (`fpNeg()` already returns an FPRef).

4814555c46 Fix inconsistent emission of `gparams_register_modules.cpp`, 
``install_tactics.cpp`` and ``mem_initialiszer.cpp`` files between
the CMake and Python build systems.

The problem was that the generated files were

* Senstive to the order component directories were traversed
* For CMake there are two directories (a source and build directory)
  for every component rather than a single directory like the
  Python build system has.

To fix this a new function ``sorted_headers_by_component()`` has been
added which defines a order that is consistent between both build
systems. This function is then used on lists of paths to discovered
header files.

75af362b25 Fix inconsistent emission of `z3consts.py`. 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.

a2376b1016 Try to fix #510. The breakage was caused by #498. 
The issue here is that in Python2 ``exec`` is a statement and
``exec`` is a function in Python3. For the ``exec`` statement to
work we would need to write

```
exec line.strip(' \n') in  exec_globals, None
```

We could write a wrapper function to do the right thing depending
on the Python version but a better approach is to actually just
use ``eval()`` rather than ``exec()`` because

* ``eval()`` is less "evil" than ``exec()`` because it only evaluates
  a single expression. My testing so far seems to indicate that this is
  sufficient.

* ``eval()`` is function in both Python 2 and 3 so we don't need
  to specialise the code based on Python version.

04ca873abb [CMake] Provide a way to customise the install directories used for 
executables, include files and libraries. We use
``GNUInstallDirs.cmake`` which ships with CMake to do the difficult work
of setting a sensible default and setting up CMake cache variables.
These can be overriden when running CMake by setting the
``CMAKE_INSTALL_BINDIR``, ``CMAKE_INSTALL_INCLUDEDIR`` and
``CMAKE_INSTALL_LIBDIR`` cache variables.
