Split up dive data structure declarations into 'dive.h'
The dive parser should eventually be just a part of the program, not the whole thing. So start preparing for that. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

- * Some silly typedefs to make our units very explicit.
- *
- * Also, the units are chosen so that values can be expressible as
- * integers, so that we never have FP rounding issues. And they
- * are small enough that converting to/from imperial units doesn't
- * really matter.
- *
- * We also strive to make '0' a meaningless number saying "not
- * initialized", since many values are things that may not have
- * been reported (eg tank pressure or temperature from dive
- * computers that don't support them). But sometimes -1 is an even
- * more explicit way of saying "not there".
- *
- * Thus "millibar" for pressure, for example, or "millikelvin" for
- * temperatures. Doing temperatures in celsius or fahrenheit would
- * make for loss of precision when converting from one to the other,
- * and using millikelvin is SI-like but also means that a temperature
- * of '0' is clearly just a missing temperature or tank pressure.
- *
- * Also strive to use units that can not possibly be mistaken for a
- * valid value in a "normal" system without conversion. If the max
- * depth of a dive is '20000', you probably didn't convert from mm on
- * output, or if the max depth gets reported as "0.2ft" it was either
- * a really boring dive, or there was some missing input conversion,
- * and a 60-ft dive got recorded as 60mm.
- *
- * Doing these as "structs containing value" means that we always
- * have to explicitly write out those units in order to get at the
- * actual value. So there is hopefully little fear of using a value
- * in millikelvin as Fahrenheit by mistake.
- *
- * We don't actually use these all yet, so maybe they'll change, but
- * I made a number of types as guidelines.
