[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).

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.

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.

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.
