Make atomic writes general
- Atomic writes are enabled by default
- Automatically detect if device supports atomic write and use it if
atomic writes are enabled
- Remove ATOMIC WRITE options from CREATE TABLE
- Atomic write is a device option, not a table options as the table may
crash if the media changes
- Add support for SHANNON SSD cards
