child_process: fix spawn() optional arguments

Spawn's arguments were documented to be optional, as they are for the
other similar child_process APIs, but the code was missing. Result was
`child_process.spawn('node', {})` errored when calling slice() on an
Object, now it behaves as the documentation said it would.

tls: process accumulated input

When creating TLSSocket on top of the regular socket that already
contains some received data, `_tls_wrap.js` should try to write all that
data to the internal `SSL*` instance.

test: fix http-many-ended-pipelines server close

The test was calling server.close() without waiting for the server
to have received all the requests. This would cause an ECONNRESET.
test: fix http-incoming-pipelined-socket-destroy

The test was calling server.close() after write on the socket
had completed. However the fact that the write had completed was
not valid indication that the server had received the data.

This would result in a premutaure closing of the server and
an ECONNRESET event on the client.
