c1b69e72eb MWL#17: Table elimination 
- Switch from trying to eliminate all tables at once (which didn't work)
  to the original approach of bottom-up elimination.

f260de5c07 MWL#17: Table elimination 
- Address review feedback: change expression analyzer used to be a copy-paste
  of ref analyzer. ref analyzer, besides doing ref analysis, also collected 
  info about keys which had sargable predicates. We didn't need that part here.

ef67ab4d8b MWL#17: Address 2nd post-review feedback 
- Switch from uniform graph to bipartite graph with two kinds of nodes:
  "values" (tables and fields) and "modules" (t.col=func(...) equalities, 
  multi-equalities, unique keys, inner sides of outer joins).
- Rename functions, classes, etc.

b43fb3e915 Correct a merge error that happened during a backport for 5.0.82sp1: 
The test for the 45806 entry in our bug DB got applied twice,
in different places for the "view.test" and "view.result" files.

The fix is to simply remove the erroneous insertion.

171b5d52af Always compile with __NT__ on windows. in 5.1 itthis #define is 
widely used, in replication (delete_allow_opened) and for named
pipe support. We do not support Win9x anymore.
