Current patch-set is preliminary to finishing DD integration.
It gets rid off all functional fields from original SQLite's struct
Index and struct Table, which can be substituted with corresponding
fields from server structures or be calculated using them.

It is worth mentioning ninth patch in series which removes support of
ON CONFLICT error actions related to index uniqueness. Firstly, alongside
with it INSERT and UPDATE code generation has been slightly simplified:
removed a lot of excess register allocations; moved cursors' allocations
closer to their usages (auxiliary cursors on secondary indexes are
required only to process REPLACE or IGNORE conflict actions);
significantly reworked function which generates code to process
constraint checks. To sump up, all these changes result in fixing
assertion fault during INSERT OR REPLACE and incorrect behavior
of UPDATE OR IGNORE statements.

* To those who will review *
I deliberately separated all commits on removing fields since this way
seems to be easier to review and understand provided changes.
After review I can squash some of them, if you want so.
