- Allow setting NetBIOS ComputerName through registry. 

- Keep old behavior as default, using new config option to change.
- Implement SetComputerName(), SetComputerNameEx(),
  GetComputerNameEx().
- ComputerName initialization moved to kernel32.

<para>
If this option is set to "Y" or missing, Wine will set the
NetBIOS name to the Unix host name of your computer, if
necessary truncated to 31 characters. The Unix hostname is the output
of the shell command <command>hostname</command>, up to and not
including the first dot ('.'). Among other things, this means that
Windows programs running under Wine cannot change the NetBIOS computer name.
</para>
<para>
If this option is set to "N", Wine will use the registry value above
to set the NetBIOS name. Only if the registry entry doesn't exist (usually
only during the first wine startup) it will use the Unix hostname as
usual. Windows applications can change the NetBIOS name. The change
will be effective after a "Reboot", i.e. after restarting Wine.
