a7fc252b0a Enhance the EXPLAIN QUERY PLAN output to use symbolic names to describe 
subqueries, where possible, instead of cryptic subquery index numbers.
And in other ways, make the EQP output cleaner and easier to read.  Little
code is changed, but many of the test results had to be tweaked to align
with the new output format.

70bd2124ed Change the RETURNING algorithm so that outputs accumulate in an ephemeral 
table until all modifications have been completed, and only then do results
start being returned.  This should help prevent problems with interleaved
sqlite3_step() calls on two separate DML statements.  It also seems to be
closer to how PostgreSQL works, which might prevent compatibility problems.
