RFC: reducing wasted disk space from addon files

[Olivier F. R. Dierick]

I have more than one version of wine installed and more than one
wineprefix.
I added a configuration file in each wineprefix that remember the wine
version used, and my scripts use that to launch the apps in the prefix
with the proper wine version.

Since the wine versions may depend on different wine-mono version, the
sharing mechanism would have to allow parallel installation of multiple
wine-mono versions, and wine would have to make the prefix link to the
right wine-mono shared install. Updating the prefix with another wine
version will have to update the wine-mono link to the right wine-mono
shared install, when it differs.

Whatever sharing mechanism that will end up in wine would have to handle
that situation.

Also, having to use another filesystem type/partition is not a solution.
It must work on ANY filesystem used by the user.
