When the Java class parser began culling unused constructors, the
logic for determining whether a given Java class has a no-arg
constructor broke when the no-arg constructor is culled. Add
an explicit field for tracking the no-arg constructor property.

With the introduction of constructors Java side, all types
become entry points into the library. However the library
was only initialized by the main class until now, resulting
in all other constructors hitting linker errors until an
interaction with the main library class.
This CL fixes that by changing each generated type to touch
the main library class, ensuring that the underlying native
library is loaded.

Before this CL, generated Java classes or interfaces were inner
classes to the top package class. That is both unnecessary and creates
ugly class names. Instead, move every generated class and interface to its
own package level class.
NOTE: This is a backwards incompatible change and requires every client
of gomobile APIs to be updated to leave out the package class in the
type names. For example, the Go type
package pkg
type S struct {
}
now generates (with the default java package name go) a Java class named
go.pkg.S. The name before this CL was go.pkg.Pkg.S.
Also, change the custom java package to specify the package prefix and
not the full package as before. This is an unfortunate change needed
to avoid name clashes between two bound packages. On the plus side,
the change brings the custom package case closer to the default behaviour,
which is a commen prefix, "go.", and a distinct java package for every
Go package bound.

Gobind uses strings for passing errors across the language barrier.
However, since Gobind doesn't have a concept of a nil string, it
can't separate an empty native string from a nil string.
In turn, that means that empty errors, exceptions or NSError * with
an empty description are treated as no error. With ObjC, empty errors
are replaced with a default string to workaround the issue, while
with Java empty errors are silently ignored.
Fix this by replacing strings with actual error objects, wrapping
the Go error, Java Throwable or ObjC NSError *, and letting the
existing bind machinery take care of passing the references across.
It's a large change for a small corner case, but I believe objects
are a better fit for exception that strings. Error objects also
naturally leads to future additions, for example accessing the
exception class name or chained exception.

The issue here is that after the split on GOMOBILEFLAGS, if
GOMOBILEFLAGS contained more than one parameter, ie "-javapkg my.pkg",
then the array gets aggregated into cmd, ie ["string1", ["-javapkg",
"my.pkg"], "string2"]. When join() is later called on cmd, this results
in a string looking like this: "string1 L[javajunk...] string2"
The cmd.addAll instead uses cmd's underlying Array Collection
interface to add all the elements from the gomobileFlags.split(" ")
call.
