Release 2.0 (2014-08-30)
B Make this wrapper compile under Go 1.3 and newer.
I Change the layout of some Target structures. This is needed to
simplify the marshalling code. The new target structures also follow
the underlying C structures more closely.
I Some names where changed to match Go naming conventions. This was
done now as I believe it is better to lump incompatibly changes into
one release as much as possible.
C Error strings were converted to lower case.
B Some typos where fixed in comments.
