WP_HTTP: Clean up some comments style and remove outdated information. 

The change to the proxy block here is for consistency, WP_HTTP_Proxy::block_request() is never called before parse_url() has successfully operated on the URL, and in the event we cannot read the URL, it shouldn't be requested.

/**
* WordPress HTTP Class for managing HTTP Transports and making HTTP requests.
*
* This class is called for the functionality of making HTTP requests and replaces Snoopy
* functionality. There is no available functionality to add HTTP transport implementations, since
* most of the HTTP transports are added and available for use.
*
* There are no properties, because none are needed and for performance reasons. Some of the
* functions are static and while they do have some overhead over functions in PHP4, the purpose is
* maintainability. When PHP5 is finally the requirement, it will be easy to add the static keyword
* to the code. It is not as easy to convert a function to a method after enough code uses the old
* way.
* This class is used to consistently make outgoing HTTP requests easy for developers
* while still being compatible with the many PHP configurations under which
* WordPress runs.
*
* Debugging includes several actions, which pass different variables for debugging the HTTP API.

* 'blocking' is the default, which is used to tell the transport, whether it should halt PHP
* while it performs the request or continue regardless. Actually, that isn't entirely correct.
* Blocking mode really just means whether the fread should just pull what it can whenever it
* gets bytes or if it should wait until it has enough in the buffer to read or finishes reading
* the entire content. It doesn't actually always mean that PHP will continue going after making
* the request.
* The 'blocking' parameter can be used to specify if the calling code requires the result of
* the HTTP request. If set to false, the request will be sent to the remote server, and
* processing returned to the calling code immediately, the caller will know if the request
* suceeded or failed, but will not receive any response from the remote server.
