If the deprecated NODE_REPL_HISTORY_FILE is set to default
node history file path ($HOME/.node_repl_history) and the file
doesn't exist, then node creates the file and then crashes when
it tries to parse that file as JSON thinking that it's an older
JSON formatted history file. This fixes that bug.

This patch also prevents node repl from throwing if the old
history file is empty or if $HOME/.node_repl_history is empty.

socket.destroy() triggers a 'close' event from the socket which triggers
the onClose handler of HTTPAgent which calls self.removeSocket(). So by
calling self.removeSocket() prior to socket.destroy() we end up with two
calls to self.removeSocket().

If there are pending requests, removeSocket ends up creating a new socket.
So if there are pending requests, each time a request completes, we tear
down one socket and create two more. So the total number of sockets grows
exponentially and without regard for any maxSockets settings. This was
noticed in https://github.com/nodejs/node/issues/4050. Let's get rid of
the extra calls to removeSocket so we only call it once per completed
request.

On Windows there can exist some race condition where the
notification of the client's `socket.destroy()` isn't received
before the server writes to the socket. This race condition was
more evident/reproducible on a single core system.

This commit fixes the flakiness by waiting until the server's
connection event handler has been called to destroy the client
socket and perform the server socket write.

process.hrtime() was performing too many operations in C++ that could be
done faster in JS. Move those operations over by creating a length 4
Uint32Array and perform bitwise operations on the seconds so that it was
unnecessary for the native API to do any object creation or set any
fields.

This has improved performance from ~350 ns/op to ~65 ns/op. Light
benchmark included to demonstrate the performance change.
