So originally I introduced the aboutToQuit() stuff in the hope to
cleanly shutdown the flow graph, including the Qt widgets blocks
before the Qt stuff is torn down.
Turns out that in aboutToQuit some stuff is already invalid, especially
in OpenGL and so causes SegFault on exit.
Instead this patch modify the logic so that we stop the flow graph before
Qt even begin disabling things.
The two shutdown path that exits are :
- The sig_handler in case we get TERM or INT signals
- The closeEvent() of the main window
This makes sure that both path call tb.stop() tb.wait() and also
any snippet 'main_after_stop'.

They are going to be needed in the closeEvent() Qt stuff
and this is earlier in the file ...

This fixes flowgraph generation when using connection templates with
multiple lines. Previously it would only indent the first line and
subsequent lines would have no indentation, causing a python error.

GRC used `gr.io_signaturev` to generate hierarchical block signatures.
This was only a SWIG alias to `gr.io_signature.makev`. Now, the
generator calls `gr.io_signature.makev` directly.

The import of eng_notation was removed in 678a7c2ad, and so float parameter
blocks were leading to flowgraph compilation error.
Since eng_notation is still imported in the generated python script, we can
put the call to num_to_str in the generated script, instead of calling it
during script generation.

This feature adds the ability to insert arbitrary code into the python
flowgraph. It gives a little more low-level flexibility for quickly
modifying flowgraphs and adding custom bits of code rather than having
to go and edit the generated py file
One example is synchronizing multiple USRP objects - sometimes you want
different sync than what is offered in the multi-usrp object, so you can
put a bit of code in the snippet block to do the custom synchronization

Adds an additional option to the flowgraph's "Generate Options" in GRC
called "Catch block exceptions", under the Advanced tab. This parameter
controls the catch_exceptions flag passed to top block instantiation.

- Update SWIG settings
- Update CMake
- Remove Python2 references
Note: This does not touch a lot of Python files, and many Python files
will still work with Python 2 after this commit. However, we won't allow
that in our CMake, and the support will be gone too.

eng_float params, e.g. "2.45G", are not recognized by Python and need to
be rendered as strings (with additional quotes). This is not true for
string types, which already have quotes, or regular floats and ints,
which do not need them.
