Adjust a number of places that result in WebKit's 'check-for-weak-vtables-and-externals' script reporting weak external symbols: ERROR: WebCore has a weak external symbol in it (/Volumes/Data/dev/webkit/OpenSource/WebKitBuild/Release/WebCore.framework/Versions/A/WebCore) ERROR: A weak external symbol is generated when a symbol is defined in multiple compilation units and is also marked as being exported from the library. ERROR: A common cause of weak external symbols is when an inline function is listed in the linker export file. ... These cases are caused by inline methods being marked with WTF_EXPORT (or related macro) or with an inline function being in a class marked as such, and when enabling LTO builds. For the most part, address these by removing the WEBCORE_EXPORT annotation from inline methods. In some cases, move the implementation out-of-line because it's the class that has the WEBCORE_EXPORT on it and removing the annotation from the class would be too disruptive. Finally, in other cases, move the implementation out-of-line because check-for-weak-vtables-and-externals still complains when keeping the implementation inline and removing the annotation; this seems to typically (but not always) happen with destructors.

Attachment 343380 [details] did not pass style-queue: ERROR: Source/WebCore/platform/mac/PlaybackSessionInterfaceMac.h:53: Inline functions should not be in classes annotated with WEBCORE_EXPORT. Remove the macro from the class and apply it to each appropriate method, or move the inline function definition out-of-line. [build/webcore_export] [4] Total errors found: 1 in 17 files If any of these errors are false positives, please file a bug against check-webkit-style.
That warning can be ignored for now. LTO builds succeed despite it.

OK. I've made the requested changes.
