Chris Lu d3b267bac2 Issue 15: Stress test corrupts volume 
Checked in for GThomas(tgulacsi78)

I've also met with partial writes (pipe closed on localhost), and also
met with real corruption: after some partial write, the data size in
needle header was read as some huuuuge number, which resulted in memory
panic.

Please consider the attached patch for ensuring full writes (seeks back
to the beginning on needle append error). Hope this helps.
Tested with a small tmpfs, lot of "no space left on device" :)
(sudo umount -lf /tmp/weed; mkdir -p /tmp/weed && sudo mount -o
size=128M,mode=4777 -t tmpfs tmpfs /tmp/weed && bin/weed master
-mdir=/tmp/weed -debug=true & bin/weed volume -dir=/tmp/weed
-debug=true)

Walk needed to be added to NeedleMap and CompactMap, to be able to add WalkKeys and WalkValues to volume. This is needed for iterating through all the stored needles in a volume - this was dump's purpose.

Chris Lu 8fb8ebdf14 master can redirect GET/DELETE/POST requests to volume servers. So 
clients does not always need to remember the volume server locations.
This is good for low~medium sized web site traffic.
