drh ec26ce3328 When generating the hash on the sqlite_master table in dbselftest, use an 
ORDER BY clause, since the sqlite_master table is reordered by VACUUM.

*************************************************************************
**
** 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
** );
