correctly when filling in cylinder pressures.

0d93470c50 Change fake profile behavior
If no average depth is known the current fake profile behavior is rather
unintuitive (we make up an average depth).

Instead we should assume that this is a PADI style dive log and give the
user a "rectangular" profile (actually, it's a trapecoid as we at least
try to enforce a sane ascent / descent speed). If the dive is somewhat
longer or deeper (10 min / 10 m) we even add a 3m safety stop at 5m.

Added a new dives/test0b that tries to capture the typical cases to test
this.

Fixes #398

262bc9c84b Add a string_to_depth() helper function to match our string_to_weight one
It's currently only used for the setting of the cylinder switching
depth, but now that one should work with user-specified units (so you
can set a max depth in feet even if you use metric, and vice versa).

In the future, if we also make the unit preferences something you can
pass in (with user preferences as a default argument value), we might
want to use this for parsing the XML too, so that we'd honor explicit
units in the XML strings.  But the XML input unit preferences are not
necessarily at all the same as the user preferences, so that does
require us to extend the conversion functions to do possibly explicit
unit preference selection.

1c72b8b054 const'ify our strtod() helper functions
The C library doesn't use const char pointers for legacy reasons (and
because you *can* modify the string the end pointer points to), but
let's do it in our internal implementation just because it's a nice
guarantee to have.

We actually used to have a non-const end pointer and replace a decimal
comma with a decimal dot, but that was because we didn't have the fancy
"allow commas" flags.  So by using our own strtod_flags() function, we
can now keep all the strings we parse read-only rather than modify them
as we parse them.

b9d7e440fd Make 'string_to_grams()' use proper type safe types
Make it use 'weight_t' and hide the "grams" part inside the type.  That
was the whole point of the weight_t type, after all.  Returning a
"double" was always bogus, since we internally always do integer grams
(and the function actually used "rint()" to get all the rounding right
anyway).

As a result, it's now called "string_to_weight()".

eec5dba1c2 Reinstating SURFACE_THRESHOLD test in pressure_time function
The small straight parts at the end of tank pressure lines are more of a
aesthetic issue, not causing real harm so it is no reason to remove the
SURFACE_THRESHOLD test from pressure_time function only because of this.

Also improved interpolate data debuging, rearranged
get_pr_interpolate_data and removed an unused variable from
get_pr_interpolate_data. No real change here, just trying to make the code
clearer.

8f0c8be245 Discontinuity and stall on tank pressure interpolated lines
Interpolated lines for tank pressures were presenting discontinuities
(sudden drops) and stalls (horizontal lines) with certain dive profiles.

The main reason seems to be that the discrete interpolation of tank
pressure was adding small pressure increments that could be rounded down
or up repeatedly generating cumulative rounding errors that would mean
either a delay on pressure drop that would be drawn as a sudden drop or as
a premature pressure drop that would result in a flat line.

This patch changes the way the discrete interpolation is done, so that we
don't have cumulative rounding errors distorting tank pressure lines.

To calculate accumulated pressure_time values the get_pr_interpolate_data
function was created. The fact that get_pr_interpolate_data transverses
the beginning of the plot_info entry list for each entry that needs
interpolated tank pressure isn't optimal at all. There might be a way to
properly track the data necessary to interpolate tank pressures from
inside the main pi->entry loop in fill_missing_tank_pressures.
Unfortunately I didn't manage to do it inside fill_missing_tank_pressures
so we have get_pr_interpolate_data.

The SURFACE_THRESHOLD test from pressure_time function was also removed as
no matter how shallow the diver is, if he is using the cylinder to breathe
the cylinders tank pressure should be affected.

409c2e9bcf Not everything can be done with the diveId
In commit c3fe1a9e9f ("Get rid of pointers to dive structures in the
UI") I was a bit too aggressive moving away from pointers to dives.

This is only needed for pointers that are held across operations that
could change the dive_table. I figured that it wouldn't hurt to get rid of
some more pointers as well, but it turns out I was wrong. The current dive
that we store in the Cylinder and Weight models can be a dive that isn't
in the dive_table at all: the multiEditEquipmentPlaceholder. And when
using the diveId we end up finding the original dive in the dive_table and
therefore modify the wrong structure.

This undoes two thirds of the above mentioned commit.

c3fe1a9e9f Get rid of pointers to dive structures in the UI
The assumption that the pointer will keep pointing to a valid structure is
fundamentally flawed. And even if that is true today, it might change in
the future - just don't do it. Use the diveId instead.

The exception is when you own the structure and use it within one UI
interaction during which any way to change the dive_table is disabled
(e.g., while adding / editing a dive).
