compiler problem in pvData/testApp

[Dirk Zimoch <dirk.zimoch@psi.ch>]

Hello,

Since last weekend building EPICS 7 fails in pvData/testApp.

Can please someone fix this or at least tell me which commit to check 
out so that I can compile again? Unfortunately I failed to find out what 
exactly the problem is or which old commit to check out to make it 
compile again.

In case it matters: I have this problem with several gcc versions, e.g 
4.8.5 and 6.2.1. Also with clang, but with better error message:

../../testApp/copy/testPVCopy.cpp:38:5: error: unknown type name 
'PVCopyPtr'; did you mean 'epics::pvDatabase::PVCopyPtr'?

Thus the problem seems to be namespace related. However I could not find 
out how to fix it. Using namespace epics::pvDatabase only seems to make 
things worse.
