First commit of stuff from Tremolo. C-only changes to start with.

Mostly squashing of warnings with some explicit casts, and removing some
variables that are never used.

Optimisations to render_line.

Various checks for (m)alloc failures and out of range inputs.

Change to use explicit dec_buf rather than repeated calls to alloca.

Change to use dec_method/switch rather than nested if.

Reorder of contents of codebook struct in preparation for ARM code.
