WK1: Support default actions for read-only text
https://bugs.webkit.org/show_bug.cgi?id=138552
-and corresponding-
rdar://problem/18877483

Reviewed by Tim Horton.

Source/WebCore:

WK1 now needs to do a lot of dictionary lookup operations that it did not 
previously have to handle. So this patch takes a lot of that functionality, which 
was implemented as static functions in WebPageMac for WK2 and moves it into 
WebCore.

* WebCore.exp.in:
* WebCore.xcodeproj/project.pbxproj:
* editing/DictionaryLookup.h: Added.
* editing/DictionaryLookup.mm: Added.
(WebCore::isPositionInRange):
(WebCore::shouldUseSelection):
(WebCore::rangeExpandedAroundPositionByCharacters):
(WebCore::rangeForDictionaryLookupForSelection):
(WebCore::rangeForDictionaryLookupAtHitTestResult):
* platform/mac/WebCoreSystemInterface.h:
* platform/mac/WebCoreSystemInterface.mm:

Source/WebKit/mac:

New WKSystemInterface functions that WebCore needs to use.
* WebCoreSupport/WebSystemInterface.mm:
(InitWebCoreSystemInterface):

WebActionMenuController now keeps an ivar for the WebCore::HitTestResult. This 
makes a lot of things easier.
* WebView/WebActionMenuController.h:
* WebView/WebActionMenuController.mm:

Perform the hit test ourselves instead of calling into WebView so that we can more 
easily save the WebCore::HitTestResult for ourselves.
(-[WebActionMenuController performHitTestAtPoint:]):

Clear selection for non-text menus.
(-[WebActionMenuController prepareForMenu:withEvent:]):

Re-set the _type here just to be safe.
(-[WebActionMenuController didCloseMenu:withEvent:]):

Moving this method to be next to the link actions so they can be within a pragma 
mark.
(-[WebActionMenuController _defaultMenuItemsForLink:]):

New method for default text actions — lookup and copy.
(-[WebActionMenuController _defaultMenuItemsForText:]):
(-[WebActionMenuController _copySelection:]):
(-[WebActionMenuController _lookupText:]):

If there is not already a selection, invoking the action menu on text should 
select the lookup text.
(-[WebActionMenuController _selectLookupText]):
(performDictionaryLookupForSelection):
(performDictionaryLookupForRange):

Handle text now.
(-[WebActionMenuController _createActionMenuItemForTag:withHitTestResult:]):
(-[WebActionMenuController _defaultMenuItemsForHitTestResult:]):

New enum values.
* WebView/WebUIDelegatePrivate.h:

Pass didCloseMenu on to the controller.
* WebView/WebView.mm:
(-[WebView didCloseMenu:withEvent:]):

Source/WebKit2:

WK1 now needs to do a lot of dictionary lookup operations that it did not 
previously have to handle. So this patch takes a lot of that functionality, which 
was implemented as static functions in WebPageMac for WK2 and moves it into 
WebCore.

* WebProcess/WebCoreSupport/mac/WebSystemInterface.mm:
(InitWebCoreSystemInterface):
* WebProcess/WebPage/mac/WebPageMac.mm:
(WebKit::WebPage::performDictionaryLookupForRange):
(WebKit::isPositionInRange): Deleted.
(WebKit::shouldUseSelection): Deleted.
(WebKit::rangeExpandedAroundPositionByCharacters): Deleted.
(WebKit::rangeForDictionaryLookupForSelection): Deleted.
(WebKit::rangeForDictionaryLookupAtHitTestResult): Deleted.

+        (InitWebCoreSystemInterface):
+
+        WebActionMenuController now keeps an ivar for the WebCore::HitTestResult. This

+        (-[WebActionMenuController didCloseMenu:withEvent:]):
+
+        Moving this method to be next to the link actions so they can be within a pragma 
+        mark.
