I just modified that: the driver will now just have to return
"/dev/foo"; the manager will do the job of adding the prefix. That is
convenient for several reasons:
* it makes it possible to make the GetDevice method public: if the
program asked to load a plugin, it can now ask to have one instance
created for it;
* the name of the plugin only appears in the exported in the
plugin_getname functions: there is now only one place to look at to
rename a plugin (well, there were other ways to do that, with a #define
notably, but this solution is more elegant IMHO).
* it puts the burden of managing the plugin in the manager!
