USetup meets NewInfLib

[Roel Messiant]

Hey,
This one's mostly for Eric Kohl.
Newinflib seems to be causing some issues for usetup, accessing memory it
shouldn't.
Attached are some patches that solve this.
The newinflib one fixes some pointer arithmetic, which ended up lying about
a buffer size.
This was already fixed in the host code, so I just applied the same fix to
the ros code.
The usetup patch is a hackfix. The issue here is that usetup fetches a line
from a section,
but the line is blank. Usetup treats it as a data line, and reading the data
from it results
in NULL .. which usetup tries to dereference.
I just hackfixed that one because the code hasn't changed, so it must've
worked fine with
the previous inflib. So the question end up as: is newinflib wrong here by
not trying to skip
the blank line, or should usetup keep in mind such lines can exist.. or some
third option?
WBR,
Roel Messiant
PS: I know patches belong in bugzilla, but the perceived urgency on my side
won the decision on where to post them.

Hi Roel,
I just committed your changes as they fix some of the issues. Thanks for
finding these bugs!
I also added a little change to the inf-parser that makes the parser
stop reading as soon as it finds the first null character.
Regards,
Eric
