Hi,
this patch fixes the ptx plugin's management of offloaded functions.  Currently
it has a single global list of functions.  But it should track this information
per ptx device instance.  I've moved the linked list  into the per-device data.

We were also not managing the plugin-allocated vector of offloaded functions,
with some totally bogus code in the unload routine.  This is currently not used,
because there is no unloading destructor.  The patch fixes that.

A followup patch will then be able to enable unloading.

ok for trunk?

I went ahead and committed this on the basis I probably understand the code bestat this point, and it is entirely PTX-specific.
