Add to script the new functions added in
commit 2368187e and commit e5ee6e14 which are:
signal_emitv_unlocked()
signal_emit_valist_unlocked()
so that the "<emit signal 'blabla'>" line keeps
showing after them.
This is a minor style change to better differentiate
signal name by enclosing it in single quotes.
Before:
<emit signal event on instance 0xf14e60 [GdkWaylandToplevel]>
After:
<emit signal 'event' on instance 0xf14e60 [GdkWaylandToplevel]>
- Commit f02ec2f2de added a gsignal fastpath where g_closure_invoke_va()
is directly called from g_signal_emit_valist() skipping signal_emit_unlocked_R()
altogether which it's the function used by gobject_gdb.py to detect
signal emission.
So we update gobject_gdb.py to also detect signals which use this
g_closure_invoke_va() fastpath.
- We also update the existent code to detect marshallers to also
include these:
surface_event_marshaller()
gdk_surface_event_marshallerv()
g_type_class_meta_marshal()
g_type_class_meta_marshalv()
This allow us that for signal emissions which use those marshallers
to keep showing the signal handler frame just after the
<emit signal blabla> line.
commit bfbe7127d5 which did a code refactor in
gobject_gdb.py introduced a bug by failing to
return the signal name when a signal had no
'detail', this was preventing pretty printing
name for signals with no 'detail'.
This commit is the unmodified results of running
```
black $(git ls-files '*.py')
```
with black version 19.10b0. See #2046.

PEP8 says that:
"Comparisons to singletons like None should always be done with is or
is not, never the equality operators."
glib uses a mix of "== None" and "is None". This patch changes all
cases to the latter.
glib installs a gdb helper file named `glib.py`.
Then the "hook" file updates `sys.path` and does `import glib`.
This will fail if glib has already been imported into gdb, say
using `from gi.repository import GLib`. This is due to a namespace clash.
One fix would be to rename the gdb helper files to not clash with
other Python modules. This should be done for all such helper files.
