    Update the ssss code:

    + add the ability to encode split shares as 16bit or 24-bit values,
    which greatly simplifies input and output, and allows constant-sized
    output for given inputs.  This also gives us the ability to use larger
    primes, although space is wasted with these, and it's not immediately
    obvious what advantage would accrue.  But it's there, just in case.

    + we advertise being able to do 255 (SSSS_MAX_SHARES) shares - so
    complete the inverse table for GF(16) arithmetic modulo P for 256
    values

    + use SSSS_MAX_SHARES (255) internally, rather than the previous
    internal (and much smaller) limits

    + simplify the I/O in this library - it was a remnant from 1993

    + remove private structs and definitions from the header file - they're
    not part of the public interface, and shouldn't be exposed

    + add ssss_split_vec() and ssss_combine_vec() which give input and
    oputput to split and combine via struct iovec

    + update the manual page
