Before this change `go list <pkg>` was used to sanitize the import
path of the package argument. That doesn't work well for building
Go source files directly:
gio -target android helloworld.go
where `go list helloworld.go` simply returns "command-line-arguments".
A better way is to leave the package path alone, and compute the
output file separately from the import path, as reported by
`go list -f {{.ImportPath}} <pkg>`.

Replace the StageDead stage with DestroyEvent dedicated to ending
the event loop and, for premature window closes, the error.
Drop the error return from NewWindow; any errors in window creation
will appear as an immediate DestroyEvent with its Err field set.

Replace CreateWindow with NewWindow that immediately creates a Window
ready to use.
Drop the Windows channel of windows created by the system. For iOS
and Android where the system creates the windows, let them rendezvous
with the window created in the first NewWindow call.
Android is further changed so that destroying and re-creating the
Java Activity simply reconnects with the original Window.

Redrawing should only be scheduled when some UI state has changed.
Window has no way to know whether a CommandEvent was ignored by
the client, so push the onus to the client to schedule a redraw.

Single stepping events only makes sense for widgets with complex
state, e.g. the text.Editor. For the input.Events source, returning
all events in a single Events call is sufficient and more natural
for clients.

Before this change, the weight applied to the space left, not the
total space available after rigid children.
While here, ensure that weight sums > 1 are capped to the available
space.

The type and argument to Flex.Flexible does not carry its weight;
It is just as easy to expand the constraint directly.
While we're here, rename the flex argument to weight which is clearer.
With this change, a List l can be iterated with
for l.Init(...); l.More(); l.Next() {
l.Elem(..., l.Constraints(), l.Index())
}
instead of
l.Init(...)
for {
i, cs, ok := l.Next()
if !ok {
break
}
l.End(..., cs, i))
}
