The maximum number of bits int the prefix code for
p(0) is 4. By setting it as 3, we were missing the
last 0 bit.
This fixes bug #4715 present on the trac.

Also change the type of begin, end and smp to ptrdiff_t to make the
comparison well-defined.

If begin is smaller than t, the subtraction 'begin -= t' wraps around,
because begin is unsigned. The same applies for end < t.
This causes segmentation faults.

If the same idx is used for more than one i, at least one entry in
sconf->chan_pos remains uninitialized.
This can cause segmentation faults.
