Merged the decimal-branch (revisions 54886 to 58140). Decimal is now
fully updated to the latests Decimal Specification (v1.66) and the
latests test cases (v2.56).
Thanks to Mark Dickinson for all his help during this process.

+version: 2.56
+
+-- This set of tests tests the extended specification 'round-to-integral
+-- value-exact' operations (from IEEE 854, later modified in 754r).
+-- All non-zero results are defined as being those from either copy or
+-- quantize, so those are assumed to have been tested extensively
+-- elsewhere; the tests here are for integrity, rounding mode, etc.
+-- Also, it is assumed the test harness will use these tests for both
+-- ToIntegralExact (which does set Inexact) and the fixed-name
+-- functions (which do not set Inexact).
+
+-- Note that decNumber implements an earlier definition of toIntegral
+-- which never sets Inexact; the decTest operator for that is called
+-- 'tointegral' instead of 'tointegralx'.
