src/sn_network.c: Implement shifting when using the bitonic merge.
Before adding the bitonic merger to a concatenated network, shift it by
a random amount of inputs. Because the merger is *bitonic* it'll still
be able to merge the result correctly.

Imported the initial C files that make up a decent sorting network toolkit already.
The files built up to know are:
- sn-cut: Does a min/max cut on a given input.
- sn-merge: Merges two networks (files) by appending a bitonic merge.
- sn-show: Pretty-prints a network to stdout.
