So far, the fields for the two SAC rates did not show a unit and were implictly l/min.
Now they respect the settings for volume units. This was harder than I thought for two reasons:
1) Imperial units for SAC are cuft/min but a typical value would be .70. So I made the point
the field prefix and what is entered is actually hundreth of cuft per minute.
2) I had to get the rounding right in order not to get effects like 20l/min become .70 cuft/min (19800 ml/min
internally) which would then become 19l/min when switching back.
While being at it, I gave the gradient factors '%'-signs as units.

We had pointers to data structures on the stack which we frequently
reallocated. These data structure contain basically a filename and an
offset. We then create a hash of the pointers to those datastructures with
the filename being the key. And then we passed those pointers around
through a Qt model(!!!) only in order to then later look up by filename
what the offset might be.
I am at a loss for words for the lunacy behind this design.
How about we just remember the offsets and pass the integers around?

Almost invisible, mostly looking like an odd bug in the profile code,
there was a tiny red line at depth 0 in the planned profile. Turns out
that was the missing mean depth. We didn't populate enough data in the
dive computer of the dive we generated from the plan (and the length of
the depth line was incorrectly determined by the duration of the dive
instead of the duration stored in the dive computer).

We were actually searching dives which match the dowloaded position
fixes. So we're also trying to take into account if the fix is automatic
or no based on a limited amount of predefined strings (bad idea, as the
user can change in companion app settings the predefined string).
This way, in actual implementation, if program concludes that a fix has
been manually got or, simply, the user is unlucky enough to have all the
position fixes out of the dive time, find_dive_n_near() function will
pair fix and dive in an ordered way (1st fix -> 1st dive; 2nd fix -> 2nd
dive ...) which is probably erroneous, except for manual position fixes.
BTW actual implementation can't pair the same gps position with more
than one dive, which would be the case, e.g. in repetitive dives while at
anchor in the same point.
The patch changes the logic:
- Search positions for defined dives (instead of dives for defined
positions) without care if position has manually or automatically been
set.
- Only take care of those dives that don't have a position yet.
- It makes two assumptions:
a.- If the position fix has been taken during the dive time, is
correct. If there are more than one inside the dive time, takes the
first one (closest to the DC's reported time).
b.- If not during diving time, the correct one is the nearest fix
before the dive begins (also the usual case if manually fixed from the
smartphone just before jump into the water). But will work too if there
is only one fix *in SAME_GROUP range* after the dive (another usual
case).
- Finally, as copy_gps_location() in dive.h is used only here, let it
take care of naming the dive if user hasn't named it yet.

I don't like that the event structure includes the variable length array.
That really makes it a pain to change the name of an event (on the flip
side, freeing events is easier I guess).
Anyway, to correctly rename an event we need to actually remove the event
from the correct dc and then add a new event with the new name. The
previous code was insane (it only worked if the new name was of smaller or
equal length, otherwise it had a beautiful buffer overflow).
And of course we need to do this both for the current_dive and the
displayed_dive.

This is kind of the inverse to copy_dive(). Instead of duplicating all the

There is massive confusion about what we display when and where and which
dive structure (or pointer to a dive structure) contains which information
at which stage. This is the first step towards restructuring all of this.
This creates a global variable displayed_dive which at any point in time
should be what is displayed on screen (both in the profile and in the
maintab). It removes the editedDive concept from MainTab.

Spin boxes for pO2 are now hooked up to preference values. Adding new
cylinders (or changing their fo2) computes the MOD accordin to the current
value of decopo2. Note that chaning the limits for deco pO2 does _not_
automatically update the switch depth of all cylinders as those might have
been manually entered.
Furthermore, MOD has now to option of rounding to multiples of a given
depth. That is used for the automatic switch depth which are now always
multiples of 3m (so that EAN50 is switched to at 21m rather than 22m).

This patch lays the foundation for differentiating
between open-circuit(OC)dives and rebreather dives
(CCR). The following were done:
1) In dive.h add an enum type dive_computer_type
2) In dive.h add two more fields to the dc structure:
a) dctype (an enum field indicating dc type)
b) no_o2sensor (indicating number of o2 sensors for this dc)
3) In parse-xml.c add a function trimspace that strips any
whitespace from a string. This is used by two functions:
utf8_string as well as by get_dc_type, described below.
The pointer to buffer is not changed in order to ensure
consistency when the buffer is freed.
4) In parse-xml.c add a function get_dc_type. This parses the
dc_type string from xml and assigns an enum value which will
later be returned to the function that parses
the dc variables.
