Server sockets should be shared by default, and client sockets should be
exclusive by default. For net/TCP, this is how it is, for dgram/UDP, its
a little less clear what a client socket is, but a socket that is
auto-bound during a dgram.send() is not usefully shared among cluster
workers, any more than an outgoing TCP connection would be usefully
shared.
Since implicit binds become exclusive, implicit/client dgram sockets can
now be used with cluster on Windows. Before, neither explicit nor
implicitly bound sockets could be used, causing dgram to be completely
unsupported with cluster on Windows. After this change, they become half
supported.

The copyright and license notice is already in the LICENSE file. There
is no justifiable reason to also require that it be included in every

as part of the entire package.
uncaughtException handlers installed by the user override the default one that
the cluster module installs, the one that kills off the master process.
Fixes#2556.
