Revert "url: support path for url.format"

This reverts commit d312b6d.

d312b6d introduced some confusion in
the existing API of url.format and url.parse.

The way the 'path' property overrides other properties in url.format's
input is too confusing for existing users compared to the issues it
fixes.

Fixes such as nodejs#9081 have been
proposed, but they do not make the API less confusing.

Instead, this change just reverts the original breaking change so that
it gives us more time after v0.12.0 is released to come up with a better
API for url.format, url.parse and other related APIs in the v0.13
development branch.

Fixes nodejs#9070.

 * `port` will only be used if `host` is absent.
 * `host` will be used in place of `hostname` and `port`
 * `pathname` is treated the same with or without the leading `/` (slash).
-* `path` is treated the same with `pathname` but able to contain `query` as well.
 * `search` will be used in place of `query`.
   * It is treated the same with or without the leading `?` (question mark)
