crypto: LazyTransform on properties, not methods

It needs to apply the Transform class when the _readableState,
_writableState, or _transformState properties are accessed,
otherwise things like setEncoding and on('data') don't work
properly.

Also, the methods wrappers are no longer needed, since they're only
problematic because they access the undefined properties.
test: fix dgram-bind-default-address on osx

Allow the IPv4-mapped-as-IPv6 style address.
http: Don't try to destroy nonexistent sockets

Fixes #3740

In the case of pipelined requests, you can have a situation where
the socket gets destroyed via one req/res object, but then trying
to destroy *another* req/res on the same socket will cause it to
call undefined.destroy(), since it was already removed from that
message.

Add a guard to OutgoingMessage.destroy and IncomingMessage.destroy
to prevent this error.
os: Fix uname() error handling on sunos

The uname function can return any non-negative int to indicate success.

Strange, but that's how it is documented.  This also fixes a similar
buffer overflow in the even more unlikely event that info.release is
> 255 characters, similar to how 78c5de5 did for info.sysname.
