-  Generate tables for a byte-wise 32-bit CRC calculation on the polynomial:
-  x^32+x^26+x^23+x^22+x^16+x^12+x^11+x^10+x^8+x^7+x^5+x^4+x^2+x+1.
-
-  Polynomials over GF(2) are represented in binary, one bit per coefficient,
-  with the lowest powers in the most significant bit.  Then adding polynomials
-  is just exclusive-or, and multiplying a polynomial by x is a right shift by
-  one.  If we call the above polynomial p, and represent a byte as the
-  polynomial q, also with the lowest power in the most significant bit (so the
-  byte 0xb1 is the polynomial x^7+x^3+x+1), then the CRC is (q*x^32) mod p,
-  where a mod b means the remainder after dividing a by b.
-
-  This calculation is done using the shift-register method of multiplying and
-  taking the remainder.  The register is initialized to zero, and for each
-  incoming bit, x^32 is added mod p to the register if the bit is a one (where
-  x^32 mod p is p+x^32 = x^26+...+1), and the register is multiplied mod p by
-  x (which is shifting right by one and adding x^32 mod p if the bit shifted
-  out is a one).  We start with the highest power (least significant bit) of
-  q and repeat for all eight bits of q.
-
-  The first table is simply the CRC of all possible eight bit values.  This is
-  all the information needed to generate CRCs on data a byte at a time for all
-  combinations of CRC register values and incoming bytes.  The remaining tables
-  allow for word-at-a-time CRC calculation for both big-endian and little-
-  endian machines, where a word is four bytes.

-   Examine all possible Huffman codes for a given number of symbols and a
-   maximum code length in bits to determine the maximum table size for zilb's
-   inflate.  Only complete Huffman codes are counted.
-
-   Two codes are considered distinct if the vectors of the number of codes per
-   length are not identical.  So permutations of the symbol assignments result
-   in the same code for the counting, as do permutations of the assignments of
-   the bit values to the codes (i.e. only canonical codes are counted).
-
-   We build a code from shorter to longer lengths, determining how many symbols
-   are coded at each length.  At each step, we have how many symbols remain to
-   be coded, what the last code length used was, and how many bit patterns of
-   that length remain unused. Then we add one to the code length and double the
-   number of unused patterns to graduate to the next code length.  We then
-   assign all portions of the remaining symbols to that code length that
-   preserve the properties of a correct and eventually complete code.  Those
-   properties are: we cannot use more bit patterns than are available; and when
-   all the symbols are used, there are exactly zero possible bit patterns
-   remaining.
-
-   The inflate Huffman decoding algorithm uses two-level lookup tables for
-   speed.  There is a single first-level table to decode codes up to root bits
-   in length (root == 9 in the current inflate implementation).  The table
-   has 1 << root entries and is indexed by the next root bits of input.  Codes
-   shorter than root bits have replicated table entries, so that the correct
-   entry is pointed to regardless of the bits that follow the short code.  If
-   the code is longer than root bits, then the table entry points to a second-
-   level table.  The size of that table is determined by the longest code with
-   that root-bit prefix.  If that longest code has length len, then the table
-   has size 1 << (len - root), to index the remaining bits in that set of
-   codes.  Each subsequent root-bit prefix then has its own sub-table.  The
-   total number of table entries required by the code is calculated
-   incrementally as the number of codes at each bit length is populated.  When
-   all of the codes are shorter than root bits, then root is reduced to the
-   longest code length, resulting in a single, smaller, one-level table.
-
-   The inflate algorithm also provides for small values of root (relative to
-   the log2 of the number of symbols), where the shortest code has more bits
-   than root.  In that case, root is increased to the length of the shortest
-   code.  This program, by design, does not handle that case, so it is verified
-   that the number of symbols is less than 2^(root + 1).
-
-   In order to speed up the examination (by about ten orders of magnitude for
-   the default arguments), the intermediate states in the build-up of a code
-   are remembered and previously visited branches are pruned.  The memory
-   required for this will increase rapidly with the total number of symbols and
-   the maximum code length in bits.  However this is a very small price to pay
-   for the vast speedup.
-
-   First, all of the possible Huffman codes are counted, and reachable
-   intermediate states are noted by a non-zero count in a saved-results array.
-   Second, the intermediate states that lead to (root + 1) bit or longer codes
-   are used to look at all sub-codes from those junctures for their inflate
-   memory usage.  (The amount of memory used is not affected by the number of
-   codes of root bits or less in length.)  Third, the visited states in the
-   construction of those sub-codes and the associated calculation of the table
-   size is recalled in order to avoid recalculating from the same juncture.
-   Beginning the code examination at (root + 1) bit codes, which is enabled by
-   identifying the reachable nodes, accounts for about six of the orders of
-   magnitude of improvement for the default arguments.  About another four
-   orders of magnitude come from not revisiting previous states.  Out of
-   approximately 2x10^16 possible Huffman codes, only about 2x10^6 sub-codes
-   need to be examined to cover all of the possible table memory usage cases
-   for the default arguments of 286 symbols limited to 15-bit codes.
-
-   Note that an unsigned long long type is used for counting.  It is quite easy
-   to exceed the capacity of an eight-byte integer with a large number of
-   symbols and a large maximum code length, so multiple-precision arithmetic
-   would need to replace the unsigned long long arithmetic in that case.  This
-   program will abort if an overflow occurs.  The big_t type identifies where
-   the counting takes place.
-
-   An unsigned long long type is also used for calculating the number of
-   possible codes remaining at the maximum length.  This limits the maximum
-   code length to the number of bits in a long long minus the number of bits
-   needed to represent the symbols in a flat code.  The code_t type identifies
-   where the bit pattern counting takes place.

-
-      syms: number of symbols remaining to code
-      left: number of available bit patterns at length len
-      len: number of bits in the codes currently being assigned
-
-   Those indices are constrained thusly when saving results:
-
-      syms: 3..totsym (totsym == total symbols to code)
-      left: 2..syms - 1, but only the evens (so syms == 8 -> 2, 4, 6)
-      len: 1..max - 1 (max == maximum code length in bits)
-
-   syms == 2 is not saved since that immediately leads to a single code.  left
-   must be even, since it represents the number of available bit patterns at
-   the current length, which is double the number at the previous length.
-   left ends at syms-1 since left == syms immediately results in a single code.
-   (left > sym is not allowed since that would result in an incomplete code.)
-   len is less than max, since the code completes immediately when len == max.
-
-   The offset into the array is calculated for the three indices with the
-   first one (syms) being outermost, and the last one (len) being innermost.
-   We build the array with length max-1 lists for the len index, with syms-3
-   of those for each symbol.  There are totsym-2 of those, with each one
-   varying in length as a function of sym.  See the calculation of index in
-   count() for the index, and the calculation of size in main() for the size
-   of the array.
-
-   For the deflate example of 286 symbols limited to 15-bit codes, the array
-   has 284,284 entries, taking up 2.17 MB for an 8-byte big_t.  More than
-   half of the space allocated for saved results is actually used -- not all
-   possible triplets are reached in the generation of valid Huffman codes.
- */
-
-/* The array for tracking visited states, done[], is itself indexed identically
-   to the num[] array as described above for the (syms, left, len) triplet.
-   Each element in the array is further indexed by the (mem, rem) doublet,
-   where mem is the amount of inflate table space used so far, and rem is the
-   remaining unused entries in the current inflate sub-table.  Each indexed
-   element is simply one bit indicating whether the state has been visited or
-   not.  Since the ranges for mem and rem are not known a priori, each bit
-   vector is of a variable size, and grows as needed to accommodate the visited
-   states.  mem and rem are used to calculate a single index in a triangular
-   array.  Since the range of mem is expected in the default case to be about
-   ten times larger than the range of rem, the array is skewed to reduce the
-   memory usage, with eight times the range for mem than for rem.  See the
-   calculations for offset and bit in beenhere() for the details.
-
-   For the deflate example of 286 symbols limited to 15-bit codes, the bit
-   vectors grow to total approximately 21 MB, in addition to the 4.3 MB done[]
