[KDE/Mac] pintentry-qt4 integrated upstream

[Till Adam]

Folks,

I wanted to give the interested parties a heads up that we've managed to get 
pinentry-qt4, the Qt4 rewrite of the pinentry application for the gnupg crypto 
stack, integrated into upstream gnupg. So now there is a pinentry available 
that will look and work the same way on all relevant platforms. We based this 
on the initial version in playground, written by Ingo Kloecker, if I remember 
correctly, added a bunch of features like use of secmem, a password strength 
meter, etc, to bring it to feature parity with and to the same level of 
security as the other pinentry implementations in gnupg (console, gtk+, native 
Windows). It is now integrated with gnupg's pinentry subversion module and 
package and built as part of that if qt4 is found on the system. It can 
crosscompile to windows via gcc's mingw target and builds natively on Mac and 
Linux. It also builds natively on Windows, in theory, using cygwin's autotools 
support. We have not been able to convince the gnupg community of moving to 
cmake. Yet. ;) Since this is a standalone binary it should also work fine in 
otherwise MSVC built KDE installations, for example, no linking required.

This means that the version in playgroud should be deprecated and no longer 
packaged. Maybe we should remove it, or mark it as read-only? Ingo?

We, that is KDAB, Intevation and g10-code, are committed to maintaining this 
version of pinentry along with the rest of gnupg and kdepim, of course. Making 
this work has been a joint effort of said companies.

Cheers,

Till
