Make sure both DELETE and PUT requests properly handle redirection requests
to address the issue reported in bug# 267063. In the process of addressing the
afformentioned bug the following related changes and cleanups were performed:

- Removed the check for HTTP_POST on redirection so that kio_http behaves
exactly like Firefox and Chromium except for HEAD requests. Converting
HEAD requests to GET makes no sense.

- Changed both ::del and ::put to leave the query component of the request
URL alone except for WebDAV requests. Not sure why it is removed for DAV
requests either.

- Changed ::del to properly handles any message body returned by the server.

- Renamed sendHttpPutError to sendHttpError and converted it to handle HTTP
response code errors for all HTTP methods, not just PUT.

- Changed proceedUntilResponseContent to use the new sendHttpError function
to send error to the client.

- Converted both ::del and ::put to use proceedUntilResponseContent since it
now correctly handles errors returned by the server.
