2LL << (wrap_bits=64 - 1) does not fit in int64_t; change the

ensure wrap_bits <= 64.

11a940adbc Fix undefined shift on assumed 8-bit input. 
decode_user_data() attempts to create an integer |build|
value with 8 bits of spacing for 3 components. However
each component is an int32_t, so shifting each component
is undefined for values outside of the 8 bit range.

This patch simply clamps input to 8-bits per component
and prints out a warning that the values were clamped.

When a channel formula ends with a subtraction, the next formula will
otherwise have its first coefficient negated.

a7aac19933 vc2enc_dwt: pad the temporary buffer by the slice size 
Since non-Haar wavelets need to look into pixels outside the frame, we
need to pad the buffer. The old factor of two seemed to be a workaround
that fact and only padded to the left and bottom. This correctly pads
by the slice size and as such reduces memory usage and potential
exploits.
Reported by Liu Bingchang.

Ideally, there should be no temporary buffer but the encoder is designed
to deinterleave the coefficients into the classical wavelet structure
with the lower frequency values in the top left corner.
