[PATCH 1/2] user32/tests: Protect OpenClipboard() from interference.

Fri Jun 4 07:39:09 CDT 2021
Applications using ole32's clipboard API (e.g. Radeon / QT5) end up
monitoring the content of the clipboard and calling OpenClipboard()
while user32:clipboard runs. This causes the test's own
OpenClipboard() calls to fail.
Similarly the KDE clipboard manager may query the Wine clipboard
content while the test runs, causing winex11.drv to call
OpenClipboard() with the same effect.
So call OpenClipboard() again when it fails due to the clipboard
already being open. If opening the clipboard still fails, trace who
opened the clipboard, particularly the window class name to help
identify the source of interference.

This patchset should fix all the failures on cw-rx460 and cw-gtx560. It
will also fix most failures in Wine + KDE.
