New scheme for managing platform-specific regress test result files.

Instead of hard-wiring one result file per platform, there is a map file
'resultmap' that says which one to use --- a lot like template/.similar.
I have only created entries in resultmap for my own platform (HPUX) so
far; feel free to add lines for other platforms.

+Platform-specific comparison files
+
+  Since some of the tests inherently produce platform-specific results,
+  we have provided a way to supply platform-specific result comparison
+  files.  Frequently, the same variation applies to multiple platforms;
+  rather than supplying a separate comparison file for every platform,
+  there is a mapping file that defines which comparison file to use.
+  So, to eliminate bogus test "failures" for a particular platform,
+  you must choose or make a variant result file, and then add a line
+  to the mapping file, which is "resultmap".
+
+  Each line in the mapping file is of the form
+               testname/platformname=comparisonfilename
+  The test name is just the name of the particular regression test module.
+  The platform name is the platform name as printed by config.guess (in
+  the toplevel PostgreSQL src directory), or any prefix of it.  The
+  comparison file name is the name of the substitute result comparison file.
+
+  For example: the int2 regress test includes a deliberate entry of a value
+  that is too large to fit in int2.  The specific error message that is
+  produced is platform-dependent; our reference platform emits
+    ERROR:  pg_atoi: error reading "100000": Numerical result out of range
+  but a fair number of other Unix platforms emit
+    ERROR:  pg_atoi: error reading "100000": Result too large
+  Therefore, we provide a variant comparison file, int2-too-large.out,
+  that includes this spelling of the error message.  To silence the
+  bogus "failure" message on HPPA platforms,  resultmap includes
+               int2/hppa=int2-too-large
+  which will trigger on any machine for which config.guess's output
+  begins with 'hppa'.  Other lines in resultmap select the variant
+  comparison file for other platforms where it's appropriate.
