Attached the backport of support for level 1 by Markus Metz in v.info for
6.4.1.
This is needed to make r.fillnulls potentially faster/less memory
consuming.

level 1 for v.info.
Right. v.info no longer needs level 2, it tries level 2 first, if this is
not successful, it tries level 1.
There is also no need to force level 1 just to speed up things, because
v.info opens vectors with head only when trying level 2. At least this is
the original behaviour in 6.4 and earlier, it was changed recently for 6.5
and 7, I changed it back to head only. There is no need to fully open a
vector if level 2 is available.
In short, whatever happens, v.info is lightening fast and uses nearly no
memory. The level 1 option can go.
Um, v.info is fast on cli but slow when used within wxGUI with a large
vector, but that's a wxGUI thing, wxGUI collects some vector information
first before it allows you to run a module.
