In main_networkattach() and main_network2attach().

I hoped you would say something like this. I see that parts of the code 
has issues:
* xl_cmdimpl.c is way too long (and will probably still have to grow)
* code duplication in several parameter parsers
* not reentrant safe (strtok instead of strtok_r)
* Coding style (mostly 80 character limit)

So I was hoping that code cleanup was on someone's list, that saves me 
from fixing many smaller things.
Regards,
Andre.


Btw. I saw that cpuid= is still missing in libxl, I have a version 
improved over the clumsy xm interface 90% ready, but will probably not 
able to send it out still this week.
