Change the constant expression getValue signature from (SchemaContext) to
(ConnectionValues) in preparation for passing conn values into engine along
with the generic sql.
Fix warnings.
Arrange to only obtain values from passed in connection values, rather than one on schema context.
Arrange to carry along all the conn values for the various submaps in the plan.
Arrange to update nested map conn values with trigger values at runtime.
Arrange for trigger values to be set into actual plan ConnectionValues.
Rearrange transform test infrastructure to handle trigger nested plans.
Add a late resolving autoinc offset entry for the generic sql builder.  Use it
when emitting generic sql for nested plans.  Allow qso:multiinsert to delay
sorting and sql generation until runtime if part of a nested plan.  Fix some issues
with the insert into values trigger planner around autoincs in the single row
plan.
