doctool/Gjs: some more fixes for structs and unions

Stop pretending we have fields on unions (only methods are
supported).
Add minimal support (ie, don't crash) to nested structures,
that due to how ast works have namespace None (and the
transformers hard-depend on that). Uncovered by GLib's
GDoubleIEEE754, before I removed union fields.
For some reason, RegressTestStructE (anonymous union) has a
completely different behavior and generates a weird name,
while RegressLikeGnomeKeyringSchema (array of unnamed structs)
becomes array(gpointer).
Bah, one should have methods anyway...
scanner: support virtual functions with a typedef-ed callback

The field of a callback need not be anonymous, it could be a
typedef, with a proper Type node.

Fixes TelepathyGlib.BaseClient having no virtual functions
(and probably others)

Also add EXEEXT to .pc files

scanner: Fix shlib resolution on W32

GI just adds '.dll' to library name and calls it a day.  There's a
comment about how this function might work, i've used it to implement
something better.  This requires a compiler that supports
-print-search-dirs argument (i.e.  gcc) and a dlltool.
