Fix Py_DECREF being executed without holding the GIL
...
When the gdbpy_ref objects get destroyed, they call Py_DECREF to
decrement the reference counter of the python object they hold a
reference to. Any time we call into the Python API, we should be
holding the GIL. The gdbpy_enter object does that for us in an
RAII-fashion.
However, if gdbpy_enter is declared after a gdbpy_ref object in a
function, gdbpy_enter's destructor will be called (and the GIL will be
released) before gdbpy_ref's destructor is called. Therefore, we will
end up calling Py_DECREF without holding the GIL.
This became obvious with Python 3.6, where memory management functions
have asserts to make sure that the GIL is held. This was exposed by
tests py-as-string.exp, py-function.exp and py-xmethods. For example:
(gdb) p $_as_string(enum_valid)

The fix is to place the gdbpy_enter first in the function. I also
cleaned up the comments a bit and removed the unnecessary initialization
of the value variable.
