new package: "linux-lts-3.4"

Long term support kernels:
http://ltsi.linuxfoundation.org/blog/2013-01-22/ltsi-v3.4-released
default kernel: upgrade to 3.4 lts
linux headers 3.4 lts - needs refactoring
switch to 3.4lts headers
glibc: make minimum supported kernel version configurable

The minimum we support is 3.2.43 which is nixos' default kernel in
master. On every stdenv-updates merge, we will move this number up to
the previous latest default kernel.

for people who want older kernels, a "compat" setting (headers +
glibc) will soon appear
