Rework the "Simple Configuration Files" chapter so it's more
of a quick-start "how to set up your project" tutorial:
- Say how to hook up the JTAG adapter. This will help new
users, and in any case is worth spelling out somewhere.
- Streamline the previous rather haphazard presentation,
filling in some missing holes along the way:
* Suggest "project directory" structure
* Introduce new term, "user config" file (openocd.cfg)
* Talk about more options for openocd.cfg contents
* ... and about creating new config files
* Add new topic, project-specific utilities (+examples)

config files) upstream.
