Request for review (S): 7100935: win32: memmove is not atomic but is used for pd_conjoint_*_atomic operations

[Siebenborn, Axel]

7100935: win32: memmove is not atomic but is used for  pd_conjoint_*_atomic.

The fix is to replace the call to memmove by a simple copy loop.

I made the fix for windows_x86_64 and for sparc.

I added the tests for copying oops and the copy of short arrays of Volker.

I did not use the template of my original change.
However, win compiler would inline the template and so does gcc. It's strange, that Sun's compiler doesn't.
