[webkit-dev] Error handling support in DRT.

[tonikitoo (Antonio Gomes)]

It was agreed on IRC that having DRTs able to handle error pages in
not a bad thing, but good since it brings DRT closer to a real
browsers behavior. Hence, I moved on here and implemented it for QT's
DRT (see https://bugs.webkit.org/show_bug.cgi?id=31509#c0).

Currently the single test depending on it is
fast/history/back-forward-reset-after-error-handling.html (see
https://bugs.webkit.org/show_bug.cgi?id=30573), which is in gtk, win
and mac 'Skipped' for now.

Also, I've filed follow up bugs for each of these DRT to track down
the implementation of such feature for their DRTs:

* MAC -> https://bugs.webkit.org/show_bug.cgi?id=31555
* GTK -> https://bugs.webkit.org/show_bug.cgi?id=31556
* WIN -> https://bugs.webkit.org/show_bug.cgi?id=31557
