SQL (Android-SQLite, JDBC) support

[Miha-x64]

• Prototype, SQLite, observability
• SQL templates
• Create trigger-based observability which will work for external INSERT/UPDATE/DELETE statements and for multi-node applications with a shared database
• Support mutating SQL templates
• deprecate DAOs and Records

While working with locks, especially combining with JDBC, you should always be aware of SQLException or other Throwable, so best-practice is:

try {
  lockObj.lock()
  // do smth what may cause Throwable
} catch(t: Throwable) {
  // optional catch, log, rollback, recover etc.
} finally {
  lockObj.unlock()
}
