Overview
Comment:Remove the test/dbselftest.c program. In its place, add the ".selftest" command to the CLI. The new CLI version is .selftest is slightly different in that it uses SHA3 hashing instead of SHA1, so the new is subtly incompatible with the old.

Improvements to ".selftest --init". Tests are number in increments of 10 starting with 100. The tests are generated inside a SAVEPOINT. Errors are reported during test generation. Tests can be appended to existing tests. Add a test case to verify the schema. (check-in: b044b152aa user: drh tags: trunk)

*************************************************************************
**
** This program implements an SQLite database self-verification utility.
** Usage:
** 
**       dbselftest DATABASE ...
**
** This program reads the "selftest" table in DATABASE, in rowid order,
** and runs each of the tests described there, reporting results at the
** end.
**
** The intent of this program is to have a set of test database files that
** can be run using future versions of SQLite in order to verify that
** legacy database files continue to be readable.  In other words, the
** intent is to confirm that there have been no breaking changes in the 
** file format.  The program can also be used to verify that database files
** are fully compatible between different architectures.
**
** The selftest table looks like this:
**
**     CREATE TABLE selftest (
**       id INTEGER PRIMARY KEY,    -- Run tests in ascending order
**       op TEXT,                   -- "test", "regexp", "print", etc.
**       cmdtxt TEXT,               -- Usually the SQL to be run
**       expected TEXT              -- Expected results
**     );
