Preliminary code review for domain CHECK constraints patch: add documentation,

Browse Source 
make VALUE a non-reserved word again, use less invasive method of passing
ConstraintTestValue into transformExpr, fix problems with nested constraint

remove memory leak.  Domain checks still need much more work if we are going
to allow ALTER DOMAIN, however.
