Simplify dive planning code

This simplifies the dive planning code by:

- allowing empty gas mixes (which means "pick previous gas")

- avoiding unnecessary strdup/free calls (this requires us to handle
  "const char *" in the parsers, but that was already true from a code
  standpoint, just not a type one)

- re-use the "plan()" function for a successful dive plan, rather than
  open-coding the dive plan segment handling.
