Bug 156255 – Refactor Windows/GTK/EFL usage of addHTTPHeaderField to send an HTTPHeaderName instead of a String

• Status: NEW
• Component: WebKitGTK

[John Wilander]

During the https://bugs.webkit.org/show_bug.cgi?id=155602 it was noted that Windows, GTK, and EFL call ResourceResponseBase::addHTTPHeaderField() with a String reference as the header name. We should refactor these pieces to instead use HTTPHeaderName::findHTTPHeaderName() and send a HTTPHeaderName enum value to esourceResponseBase::addHTTPHeaderField(). Thus, unknown header names can be handled where error handling makes more sense.

The same goes for ResourceRequestBase::addHTTPHeaderField().

After this refactoring it should be possible to remove the addHTTPHeaderField() functions that receive HTTP header names as strings.
