Still incomplete. And I am not sure I should
support it, but it should get more people happy

This was originally meant only to eradicate the interleaving
code, so that the raw API could be slightly faster.

Turns out a lot had to be done for that, and the API changed
to reflect those changes.

The RAW_Encoder template now has enabled/disabled methods,
so that you can only use the right one, depending on
whether you choose interleaving or not.

While doing all of this, I realized a nice way to let the user
choose the correct symbol number for the block. +1 for typesafety.

And since the commit became really big, I threw in a couple
of useless style changes, bringing back everything to 80 columns.

Really, I should be doing smaller commits.
