Patched version of the Trove library - changes the Collections semantics to match proper java.util.Map semantics

This library has been patched by Palantir Technologies to make the following changes:

Branch palantir-gotham-3.12.x - used by Palantir Gotham 3.12.x:

• Trove implements of series of decorators that wrap their custom collections and implement the standard Java Collections interfaces. These decorators depart from the behavior specified in the Map interface by returning 0 when put() or remove() is called with a key not in the map. This version returns null as specified by Map.
• Trove collections use a magic primitive value to mean null when wrapped by a decorator. If this magic primitive value is actually added to the collection, decorators will treat it as null, the same way they would treat a missing value. This version distinguishes between these two cases and disallows adding null to decorators.

Branch palantir-gotham-4.x - used by Palantir Gotham 4.x:

• This version adds implementations of arrays, lists, sets, and maps that utilize offheap memory allocated by the sun.misc.Unsafe class.
