Add missing svn:eol-style property to all .cpp files. Also set svn:keywords for .cpp files which don't have that property yet to Id, including src/osx/core/glgrab.cpp for consistency (it doesn't make use of the property).

- implements YieldFor() with event filtering for wxMSW and wxGTK,
adds TODO markers in other ports;
- replaces wxYield() in GTK's clipboard code with a wxTheApp->YieldFor() call, thus fixing possible reentrancies
(and modifies clipboard sample to test synchronous IsSupported calls)
- replaces wxYieldIfNeeded() calls in wxProgressDialog with wxTheApp->YieldFor() calls, so that it processes only
UI/user-input events, thus fixing the race condition visible in the "thread" sample
- documents the new functions
