Merge git://github.com/libdivecomputer/libdivecomputer into NG-test

This adds the string field interface to the Shearwater family of dive
computers.

That includes proper serial number formatting, but it also has a lot of
new fields for battery information (both the dive computer itself and
the transmitter) but also deco model information.

Much of the deco model cases come from Anton Lundin in the original
subsurface branch, and Dirk Hohndel added the battery type and serial
number and firmware version data.  And I ended up massaging it even in
that original branch, so it blamed me for all these lines even back
there.

The sign-offs from Dirk and Anton are from the original commits.
