229fd3dc3e [CMake] Fix dependencies for generating install_tactic.cpp. 
Previously CMake was not aware of which headers files the generation
of `install_tactic.cpp` depended on. Consequently this could result
in broken incremental builds if

* Existing headers that declared tactics/probes changed.
* New tactics/probes were added to new header files.

Now the `z3_add_component()` CMake function has been modifed to take an
optional `TACTIC_HEADERS` argument which allows the headers that declare
tactics/probes to be explicitly listed. The necessary component
declarations have been modified to declare their tactic/probe header
files.

With this information CMake will now regenerate `install_tactic.cpp`
correctly.

This required the `mk_install_tactic_cpp_internal()` function to be
changed to take a list of header files rather than a list of component
source directories. The two consumers (CMake and Python/Makefile build
systems) of this function have been modified to work with this change.

This partially fixes #1030.

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.

131f9e2247 change queries to take function names instead of arbitrary predicates.
