+ *
+ * Proof:
+ *   Have |h|<=p so |q|<=1 so |19^2 2^(-255) q|<1/4.
+ *   Also have |h-2^230 h9|<2^231 so |19 2^(-255)(h-2^230 h9)|<1/4.

+ *   Write y=2^(-1)-19^2 2^(-255)q-19 2^(-255)(h-2^230 h9).
+ *   Then 0<y<1.
+ *
+ *   Write r=h-pq.
+ *   Have 0<=r<=p-1=2^255-20.
+ *   Thus 0<=r+19(2^-255)r<r+19(2^-255)2^255<=2^255-1.
+ *
+ *   Write x=r+19(2^-255)r+y.
+ *   Then 0<x<2^255 so floor(2^(-255)x) = 0 so floor(q+2^(-255)x) = q.
+ *
+ *   Have q+2^(-255)x = 2^(-255)(h + 19 2^(-25) h9 + 2^(-1))

+/*
+ * IMPLEMENTATION NOTES.
+ *
+ * As you might have noticed 32-bit hash algorithms:
+ *
+ * - permit SHA_LONG to be wider than 32-bit (case on CRAY);
+ * - optimized versions implement two transform functions: one operating
+ *   on [aligned] data in host byte order and one - on data in input
+ *   stream byte order;
+ * - share common byte-order neutral collector and padding function
+ *   implementations, ../md32_common.h;
+ *
+ * Neither of the above applies to this SHA-512 implementations. Reasons
+ * [in reverse order] are:
+ *
+ * - it's the only 64-bit hash algorithm for the moment of this writing,
+ *   there is no need for common collector/padding implementation [yet];
+ * - by supporting only one transform function [which operates on
+ *   *aligned* data in input stream byte order, big-endian in this case]
+ *   we minimize burden of maintenance in two ways: a) collector/padding
+ *   function is simpler; b) only one transform function to stare at;
+ * - SHA_LONG64 is required to be exactly 64-bit in order to be able to
+ *   apply a number of optimizations to mitigate potential performance
+ *   penalties caused by previous design decision;
+ *
+ * Caveat lector.
+ *
+ * Implementation relies on the fact that "long long" is 64-bit on
+ * both 32- and 64-bit platforms. If some compiler vendor comes up
+ * with 128-bit long long, adjustment to sha.h would be required.
+ * As this implementation relies on 64-bit integer type, it's totally
+ * inappropriate for platforms which don't support it, most notably
+ * 16-bit platforms.
