Move InsertZeroColumns and CopyColumn to ::internal.

These functions operate directly on the packet masks, and are thus not directly
involved in the FEC encoding/decoding operation. The ::internal namespace is used
for packet mask-related functions, and will be renamed later on.

This CL should have no impact on functionality or performance.
