The pointer from native is stored inside of a class which
wraps the structure. Fields can be accessed by marshalling
from and to the pointer. glib: Value.Update does now invoke
a private Update() method which is needed to update the new
structures.
Unfortunately, gir marks all integers as gint regardless
of its size. We have to check if the value will really
fit into a int, that is why there is an automatic fallback
to long.
The migration to generic collections [1] caused another regression: a
KeyNotFoundException was being thrown (instead of returning null like
HashTable did) when using the Destroyed event of the Gtk.Widget class.

A particular example of this problem is Banshee's Import Media feature,
which was generating the following stacktrace:
[1 Debug 23:24:36.898] Starting - Importing Media

Note: Applications can use GLib.ExceptionManager.UnhandledException
to handle the exception.

glib.csproj needs to reference System.Core from .NET 3.5 because
glib-sharp now[1] uses System.Action [2] delegate (not to confuse
with System.Action<T>) which was not available in .NET 2.0's System
reference. This way MonoDevelop stops marking "Action" in red color.

The only autogenerated AssemblyInfo files are in cairo and in
gtk-sharp's root, not inside other libraries like atk, glib, etc.
Removing them will make MonoDevelop stop rendering a red element
underneath each project.
Autogen.sh was grepping for the obsolete macro AM_CONFIG_HEADER, which
was replaced by AC_CONFIG_HEADERS in configure.ac. As a consequence it
was not calling autoheader, and then causing automake to fail if
config.h.in was not already present.
ListBase was throwing a NullReferenceException in DataMarshal() due
to the fact that Reflection was being used to find the adapter name
of the interface generated by the bindings, which has recently
changed [1].

This regression surfaced after 82a957bc9d [1],
when many collections were migrated to generic collections. HashTables
simply return null when queried for certain key, while Dictionary objects
throw KeyNotFoundException.
The regression could be noticed, more particularly, when trying to
compile the gtk3 branch of the gudevsharp project [2].

For example gtk_drag_start allows a null Gdk.Event so we need to marshal
it to IntPtr.Zero instead of throwing a NullReferenceException
Cherry-picked from the gtk-sharp-2.12 branch.
