[Libguestfs] Issues with GObject bindings

Matt, further to the conversation today. When you run the tests (make -C gobject check) you'll find it now prints the descriptive message: "GObject bind tests skipped: Int64, OInt64 and OStringList are all broken" That nicely sums up the first two problems. (1) When I tested passing the full range of int64, it turns out to be broken. There are probably two layers of brokenness, ie. Javascript itself has broken integers as a design failure of the language, but also I convinced myself at some point that something in GObject truncates all integers to 32 bits. BTW also check it works on a 32 bit architecture. (2) OStringList: IIRC I added this type to the generator but was unable / didn't have time to add it to the GObject bindings. (3) Stability of the API: GObject doesn't understand the once_had_no_optargs feature of the generator, which means that converting a no-optargs call to an optargs call (which is now permitted) will break the GObject API. You may or may not care about this. (4) Coverity found a potential bug in header inclusion. It seems that GObject headers recursively include themselves. Both Ondrej and I tried different approaches to fixing this but were unable to make it work. (5) I heavily refactored the code in generator/gobject.ml. Although I checked that the output of the generator didn't change, you might also want to check those commits for sanity.
