[Click] [PATCH] More number of elements configuration support.

[Joonwoo Park]

Hi,

For the second time after patch for click_qsort().
Recently I tried to configure about 4000 click elements. (Lots of
interfaces from VLAN)
But I couldn't get it due to size limitation of atomic memory
allocation of ClickIno::grow().
After configuration, 'ls -al /click/' shows nothing.
I think we need vmalloc() or kmalloc(GFP_KERNEL) at there.
I tried vmalloc() with CLICK_LALLOC()
Therefore, It showed me up to running 7500 elements. (for further more
I got a failed Vector::reserve())
I hope I didn't missed something that we can't use vmalloc instead of
kmalloc(GFP_ATOMIC) at that point.
