Previously, two versions of the `qtwidget` functions existed,
`qwidget()` and `pyqwidget()`, with the only difference being that
`qwidget()` returned a pointer to the `QWidget` object managed by the
corresponding block, while `pyqwidget()` returned that same pointer, but as
an integer (Or `PyLong` in this case).
While `qwidget()` is used by C++ code accessing the widgets,
`pyqwidget()` is only used for the python interface. This makes these
two methods redundant, thus this commit entirely removes `pyqwidget()`,
and modifies the `qwidget()` python wrapper to behave like
`pyqwidget()`. Note that we can be fairly confident that this change
will not effect potential users of `qwidget()`, because any invocation
on the objects previously returned by `qwidget()` would cause a
segmentation fault.
This commit also fixes a memory leak:
Internally, the `pyqwidget()` functions were returning a PyLong `PyObject *`,
which was then upwrapped in a pybind trampoline without decrementing
the reference count of that python object.

First batch of changes:
```
find […] -print0 | xargs -0 sed -i -r '/get_initial_sptr/{:nxt N;/;/!b nxt;s/get_initial_sptr\(\s*new ([^(]+)(.*)\)\)/make_block_sptr<\1>\2)/}'
```
Then:
* Back out `sptr_magic.h` edits
* Change some `friend` clauses
* clang-format the whole thing
* Update checksums in the pybind11 bindings files

gr-qtgui uses lambdas instead of `boost::bind` to register message
handlers now. This component makes quite heavy use of message handlers.

Replaced with horizontalAdvance (requires Qt >=5.11).

This is the last boost::lexical_cast in gnuradio.

This is C++11: you can convert
std::vector<complextype> vec;
vec.push_back(complextype(foo, bar, baz));
by
std::vector<complextype> vec;
vec.emplace_back(foo, bar, baz);
which saves one unnecessary copy.
This mostly happened in rpc code.
The automated clang-tidy check failed miserably, so most of this was
done by hand.

typical usage:
message_port_pub(pmt::mp("out_port"), …)
which is bad, as it implies hashing of a string, allocation of memory,
deallocation, finding the hashed string in the table of interned strings
and returning a unique pointer (which for reasons of PMT awesomeness
isn't even unique) to the interned port name.
Replacing all these port name ad hoc ::mp() calls by reusing one,
private, port name member.

Unlike the current QT GUI Entry Widget, this is an actual GNU Radio
block with an output message port 'msg'. When the editing is finished
(enter or change in scope), it triggers the editing_finished method
that publishes the text in the box as a message.
Also allows setting of the value through an input message port.
Adds example test_qtgui_msg.grc to explore this.
