entdec: Remove eptr, end_window, and nend_bits.

The eptr, end_window, and nend_bits fields of struct od_ec_dec are
initialized to fixed values and are never changed:
* dec->eptr is initialized to buf + storage, which is equal to dec->end.
* dec->end_window and dec->nend_bits are initialized to 0.

Removing these fields simplifies od_ec_dec_tell.

Document that od_ec_dec_refill does not change the return value of
od_ec_dec_tell.
