CCR code: Split profile.c into two files, with gas caluclations separate.

Browse source 
This patch implements a separation of the code for gas pressure
calculations from the rest of the code in profile.c. The latter
file is now split into: profile.c and gaspressures.c. The
details of the transferred functions is given at the top of
gaspressures.c. The following chnages were made:
1) dive.h: The function types of calculate_depth_to_mbar
   and depth_to_mbar were made non-static in order to make them
   available within gaspressures.c.
2) profile.c: Prototypes for the functions in gaspressures.c
   were inserted at the top of profile. Ten functions were
   transferred from profile.c to gaspressures.c
3) gaspressures.c as well as a short header, gaspressures.h
   were created.

For the gas pressure calculations for CCR dives, gaspressures.c
forms the immediate basis for further code development.
