Clean up strings.out , removed func_get_detail from error message

if an operating specific expected file exists, use that for the comparison.
This allows for "legit" differences between results, like the "Result too
large" message vs "Math result not representable" ...

Also, have the failed diffs get output to regression.diffs so that its easy to
view those tests that failed

This patch makes it possible to do a "real" make distclean (back to its
fresh state) on the distribution after compilation, regression testing,
etc.

tests running "as expected"...

Some behavior of the triggers test cases changed for the least week or two;
 now back to the usual expected behavior.

Allow varchar() to only store needed bytes.  Remove PALLOC,PALLOCTYPE,PFREE.  Clean up use of VARDATA.

Change some labels in bootparse to make ctags happy.  Clean up outfunc/readfunc code and add missing fields for Query structure and new Union fields.  Fix optimizer bug shown in new \do command.  Change WARN to ERROR in contrib and regression stuff.
