Log message:
*: more gobject-introspection clean-ups

Restore it in two bl3.mk where the .pc files actually propagate it

Log message:
*: switch to glib2-introspection

The gobject-introspection package installed _some_ of the introspection
files needed for glib2, but not all - some of them are built from the glib2
sources. glib2-introspection now contains all glib2-related introspection
files.

Add a tool dependency on the new package where needed.

Remove gobject-introspection from buildlink3.mk files - this is usually
a tool and should not be forwarded via buildlink3.

Some cleanups/fixes for -current while here.

*: bump gobject-introspection users for ABI bump

XXX: I'm actually not sure why the ABI was bumped for 1.84, but now that
it is we have to bump PKGREVISIONs, otherwise pkgin is quite unhappy
