+/* An improved random number generation package.  In addition to the standard
+   rand()/srand() like interface, this package also has a special state info
+   interface.  The initstate() routine is called with a seed, an array of
+   bytes, and a count of how many bytes are being passed in; this array is
+   then initialized to contain information for random number generation with
+   that much state information.  Good sizes for the amount of state
+   information are 32, 64, 128, and 256 bytes.  The state can be switched by
+   calling the setstate() function with the same array as was initialized
+   with initstate().  By default, the package runs with 128 bytes of state
+   information and generates far better random numbers than a linear
+   congruential generator.  If the amount of state information is less than
+   32 bytes, a simple linear congruential R.N.G. is used.  Internally, the
+   state information is treated as an array of longs; the zeroth element of
+   the array is the type of R.N.G. being used (small integer); the remainder
+   of the array is the state information for the R.N.G.  Thus, 32 bytes of
+   state information will give 7 longs worth of state information, which will
+   allow a degree seven polynomial.  (Note: The zeroth word of state
+   information also has some other information stored in it; see setstate
+   for details).  The random number generation technique is a linear feedback
+   shift register approach, employing trinomials (since there are fewer terms
+   to sum up that way).  In this approach, the least significant bit of all
+   the numbers in the state table will act as a linear feedback shift register,
+   and will have period 2^deg - 1 (where deg is the degree of the polynomial
+   being used, assuming that the polynomial is irreducible and primitive).
+   The higher order bits will have longer periods, since their values are
+   also influenced by pseudo-random carries out of the lower bits.  The
+   total period of the generator is approximately deg*(2**deg - 1); thus
+   doubling the amount of state information has a vast influence on the
+   period of the generator.  Note: The deg*(2**deg - 1) is an approximation
+   only good for large deg, when the period of the shift register is the
+   dominant factor.  With deg equal to seven, the period is actually much
+   longer than the 7*(2**7 - 1) predicted by this formula.  */
+
+
+
+/* For each of the currently supported random number generators, we have a
+   break value on the amount of state information (you need at least this many

+/* An improved random number generation package.  In addition to the standard
+   rand()/srand() like interface, this package also has a special state info
+   interface.  The initstate() routine is called with a seed, an array of
+   bytes, and a count of how many bytes are being passed in; this array is
+   then initialized to contain information for random number generation with
+   that much state information.  Good sizes for the amount of state
+   information are 32, 64, 128, and 256 bytes.  The state can be switched by
+   calling the setstate() function with the same array as was initialized
+   with initstate().  By default, the package runs with 128 bytes of state
+   information and generates far better random numbers than a linear
+   congruential generator.  If the amount of state information is less than
+   32 bytes, a simple linear congruential R.N.G. is used.  Internally, the
+   state information is treated as an array of longs; the zeroth element of
+   the array is the type of R.N.G. being used (small integer); the remainder
+   of the array is the state information for the R.N.G.  Thus, 32 bytes of
+   state information will give 7 longs worth of state information, which will
+   allow a degree seven polynomial.  (Note: The zeroth word of state
+   information also has some other information stored in it; see setstate
+   for details).  The random number generation technique is a linear feedback
+   shift register approach, employing trinomials (since there are fewer terms
+   to sum up that way).  In this approach, the least significant bit of all
+   the numbers in the state table will act as a linear feedback shift register,
+   and will have period 2^deg - 1 (where deg is the degree of the polynomial
+   being used, assuming that the polynomial is irreducible and primitive).
+   The higher order bits will have longer periods, since their values are
+   also influenced by pseudo-random carries out of the lower bits.  The
+   total period of the generator is approximately deg*(2**deg - 1); thus
+   doubling the amount of state information has a vast influence on the
+   period of the generator.  Note: The deg*(2**deg - 1) is an approximation
+   only good for large deg, when the period of the shift register is the
+   dominant factor.  With deg equal to seven, the period is actually much
+   longer than the 7*(2**7 - 1) predicted by this formula.  */
+
+
+
+/* For each of the currently supported random number generators, we have a
+   break value on the amount of state information (you need at least this many
+   bytes of state info to support this random number generator), a degree for
+   the polynomial (actually a trinomial) that the R.N.G. is based on, and
+   separation between the two lower order coefficients of the trinomial.  */

+mix -- mix 3 32-bit values reversibly.
+For every delta with one or two bit set, and the deltas of all three
+  high bits or all three low bits, whether the original value of a,b,c
+  is almost all zero or is uniformly distributed,
+* If mix() is run forward or backward, at least 32 bits in a,b,c
+  have at least 1/4 probability of changing.
+* If mix() is run forward, every bit of c will change between 1/3 and
+  2/3 of the time.  (Well, 22/100 and 78/100 for some 2-bit deltas.)
+mix() was built out of 36 single-cycle latency instructions in a 
+  structure that could supported 2x parallelism, like so:
+      a -= b; 
+      a -= c; x = (c>>13);
+      b -= c; a ^= x;
+      b -= a; x = (a<<8);
+      c -= a; b ^= x;
+      c -= b; x = (b>>13);
+      ...
+  Unfortunately, superscalar Pentiums and Sparcs can't take advantage 
+  of that parallelism.  They've also turned some of those single-cycle
+  latency instructions into multi-cycle latency instructions.  Still,
+  this is the fastest good hash I could find.  There were about 2^^68
+  to choose from.  I only looked at a billion or so.

+hash() -- hash a variable-length key into a 32-bit value
+  k     : the key (the unaligned variable-length array of bytes)
+  len   : the length of the key, counting by bytes
+  level : can be any 4-byte value
+Returns a 32-bit value.  Every bit of the key affects every bit of
+the return value.  Every 1-bit and 2-bit delta achieves avalanche.
+About 36+6len instructions.
+
+The best hash table sizes are powers of 2.  There is no need to do
+mod a prime (mod is sooo slow!).  If you need less than 32 bits,
+use a bitmask.  For example, if you need only 10 bits, do
+  h = (h & hashmask(10));
+In which case, the hash table should have hashsize(10) elements.
+
+If you are hashing n strings (ub1 **)k, do it like this:
+  for (i=0, h=0; i<n; ++i) h = hash( k[i], len[i], h);
