Reviewed by Darin Adler.

Source/WebCore: 

Before this patch, createContextualFragment threw NOT_SUPPORTED_ERR and insertAdjacentHTML didn't throw any errors.
Make them throw SYNTAX_ERR to be consistent with the spec and Firefox:
http://html5.org/specs/dom-parsing.html#parsing
http://www.whatwg.org/specs/web-apps/current-work/multipage/the-xhtml-syntax.html#xml-fragment-parsing-algorithm

Also reduced the code duplication.

Test: fast/dom/xhtml-fragment-parsing-exceptions.xhtml

* dom/Range.cpp:
(WebCore::Range::createContextualFragment):
* dom/ShadowRoot.cpp:
(WebCore::ShadowRoot::setInnerHTML): Explicitly pass AllowScriptingContent. 
* editing/markup.cpp:
(WebCore::createFragmentFromMarkup):
(WebCore::createFragmentForInnerOuterHTML): Takes ExceptionCode now.
(WebCore::createContextualFragment): Share code with createFragmentForInnerOuterHTML
and propagate the exception code.
* editing/markup.h:
* html/HTMLElement.cpp:
(WebCore::HTMLElement::setInnerHTML): Explicitly pass AllowScriptingContent.
(WebCore::HTMLElement::setOuterHTML): Ditto.
(WebCore::HTMLElement::insertAdjacentHTML): Ditto; also rename ignoredEc to ignoredEC
per Darin's comment on the bug 87339.

Source/WebKit/qt: 

Pass an ExceptionCode to createContextualFragment.

* Api/qwebelement.cpp:
(QWebElement::appendInside):
(QWebElement::prependInside):
(QWebElement::prependOutside):
(QWebElement::appendOutside):
(QWebElement::encloseContentsWith):
(QWebElement::encloseWith):

LayoutTests: 

Add a regression test, and rebaselined the existing tests since we throw
DOMException.SYNTAX_ERR instead of DOMException.INVALID_STATE_ERR.
