Replace the complex and somewhat unfixable regexp based parser for
a parser that handles each line individually. Normalize multi-line
headers to replace multiple spaces with a single one. Section 4.2 of the
HTTP1.1 standard states
> Any LWS that occurs between field-content MAY be replaced with
> a single SP before interpreting the field value or forwarding the
> message downstream.
This makes me somewhat confident that we can safely normalize
multi-line HTTP header values.

Facebook servers have now HTTP response without status string. The use
"HTTP/1.1 200 "
while CakePHP needs
"HTTP/1.1 200 Ok"
because preg_match() in code use + instead *
This statement does not serve a purpose anymore.
In a long forgotten world it indicated the main version number of PHP which the code in the file was compatible to.

But since PHP 5.1 and later this is only marginally true.
Thus I propose to remove it from CakePHP.
