This reverts commit 06cfff9.

Reverted because it introduced a regression where (because options were
modified in the later functionality) options.host and options.port would
be overridden with values provided in other, supported ways.

This commit adds a test to ensure all options are NOT modified after
passing them to http.request. Specifically options.host and options.port
are the most prominent that would previously error, but add the other
options that have default values.

options.host and options.port were overridden for the one-argument
net.createConnection(options) call.

tls.connect(options) with no options.host should accept a certificate
with CN: 'localhost'. Fix Error: Hostname/IP doesn't match
certificate's altnames: "Host: undefined. is not cert's CN: localhost"

'localhost' is not added directly to defaults because that is not
always desired (for example, when using options.socket)

If `$NODE_PATH` contains trailing separators, `Module.globalPaths` will
contains empty strings. When `Module` try to resolve a module's path,
`path.resolve('', 'index.js')` will boil down to `$PWD/index.js`, which
makes sub modules can access global modules and get unexpected result.
