Platform independent interface for tun provider. Split the long tun.c into platform specific files using tun_engine interface.
Functionality is the same. Maintenance will be much easier! new options, like stacking several interfaces and delegate partial control to plugin. There is more to be done in order to clean up the code, however this is a good starting point. Some more minor cleanups. Tested on Linux, FreeBSD, Windows. Branch should be merge after syshead[1]. Most probably patch exceeds list limitation, review is available[2]. This is for 2.4, please review quickly this so won't need to rebase. Special thanks to Eric Crist for his FreeBSD help.
