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.

2. an `'uncaughtException'` event listener is set on the process
Also fix an issue where the process would not abort in the proper

handler and `--abort-on-uncaught-exception` is used.
Finally, change the behavior of --abort-on-uncaught-exception so that,

a domain further up the domains stack has one, the process will not

When a client calls read() with a nonzero argument
on a Socket, that Socket sets this._consuming to true.
It never sets this._consuming back to false.
ChildProcess.flushStdio() currently doesn't flush
any streams where _consuming is truthy. But, that means
that it never flushes any stream that has ever been read from.
This prevents a child process from ever closing if one of
its streams has been read from, causing issue #4049. This
commit allows consuming streams to be flushed, and the
child process to emit a close event.
