Comprehensive dump module

[rogerbinns]

Currently you have to do shenanigans via the shell to get dumps. Add a module that lets you configure what you want in the dump, acting as a generator. Have some presets for eg full fidelity dump, mysql/postgres etc compatible, just the data etc

• Header fields like page_size, encoding, auto vacuum
• application id / user_version
• drop table if already exists
• A schema so it can be run against attached database
• include/exclude virtual tables and their backing data tables
• comments at the top or not
• multiple values clauses
• include/omit views and indexes
• rename indexes?
• include/exclude sqlite_stat and similar tables
• run analyze at the end
• Include rowid in insert
• insert or replace so it can run against existing table to merge into it
• foreign key state handling
