In pscr_o2() the result of a double calculation was implicitly
converted to int, which resulted in a gcc warning.
Part of the expression was explicitly converted to int, but then
subtracted from a double.
Instead, do all the calculations in double and cast the final
expression to int. This is probably the prudent thing to do.

This prevented calculation of the pressure data when dragging

As an alternative, if this turns out to be too slow, we might

The old get_maxdepth() function in profile.c was accounting for
two things:
- the partial pressure graphs
- rounding to sane value
Both are now taken care of by the profile itself. This leads to
excessive max-depths. Remove the code from profile.c.

free_plot_info_data() frees the sample and pressure arrays
and accordingly sets the corresponding pointers to NULL.
However, it doesn't clear the element-count and thus leaves
the structure in an inconsistent state.
Clear the whole structure with memset(). I am not a fan of
doing so, but there are existing memset() calls in the

Dive data are stored internally using integral types using
appropriately fine units (mm, mbar, mkelvin, etc.). These
are converted with functions defined in units.h for display
(m, bar, C, etc.). Usually floating points are returned by
these functions, to retain the necessary precision. There
is one exception: the to_PSI() and mbar_to_PSI() functions.
For consistency, make these functions likewise return floats.
This will be needed for the rework of the profile-axes.
The plan is to use the conversion functions to make the
axes aware of the displayed values. This in turn will be
necessary to place the ticks at sensible distances. However,
the conversions need to be precise, which is not the
case for the current to_PSI() functions.

For better scalability, we might replace the dive event icons

This function has accumulated quite some cruft. It seems to add
additional space to make place for certain chart features
(e.g. the average depth text item).
However, it makes no sense to solve this here, as only the
profile knows how much place is needed to display these
features.
Therefore, basically revert this to the original version,
which simply returns the maximum time for long dives
and a threshhold for short dives that depends on the
zoomed_plot setting.
The result looks more reasonable to me, as there is no
(varying!) empty space to the right of the profile.

To enable grouping by trip in the statistics module, split
the get_trip_title() function in a version that appends
a "(n dive(s)" string an one that doesn't. The statistics
module doesn't want that added string, since it displays
the number of dives in a different way.
Also, move the functions to string-format.h, where these
are collected. And rename them to camelCase. Yes, it's
ugly, but consistent with most other C++ code in the code
base.

When adding a cylinder, it was added at the end of the list.
This would make hidden cylinders visible as the new rule is
to only hide unused cylinders at the end of the list.
Therefore, add the cylinder after the last used cylinder,
i.e. before the first hidden cylinder.
This means that the position where the cylinder is added has
to be hidden in the undo command.

The D in MOD, EAD, END, and EADD stands for "depth" and
as such these should be mm in int rather than double.
The intermediate fn2 and fhe2, however, as intermediate
value should not be rounded to an integer.
The upshot of this is a litle more numerical stability.
It should lead to more stable values in TestProfile
when run on architectures with different floating

In order to not break existing behavior, we still store fingerprints on disk, but

This just adds the basic structures and the accessor functions needed to
manage a table of fingerprint data. The table is indexed by the hash of
the model name and binary serial number as created by libdivcecomputer.
This way the data is accessible when libdivecomputer fist accesses a
dive computer (which is the point in time when we need to use the
fingerprint.
The table also contains the corresponding device id and dive id so we
can verify that the current dive table still contains that dive.

Most divecomputers download data dive by dive - so we get reasonably
frequent updates during the download (as new dives are found and posted
in the progress text area). But some (like the G2) download all of the
new dives at once and only then start parsing them. As a result the
download can look like it is hung.
As a compromise this shows updates on the data received in 10kB
increments. Which for most cases should never be shown and therefore not
make the user experience any worse - but for cases like the G2 will make
a huge difference.

For some reasons prefs.bottompo2 is an integer (mbar)
whereas prefs.modpO2 is a float (bar). This results
in mixed integer/floating point arithmetics when

a warning, when storing a mbar value as an integer.

This tries to make our fingerprinting code work better, by avoiding
using the "deviceid" field that has always been unreliable because we've
calculated it multiple different ways, and even for the same version of
subsurface, it ends up changing in the middle (ie we calculate one value
initially, then re-calculate it when we have a proper serial number
string).
So instead, the fingerprinting code will look up and save the
fingerprint file using purely "stable" information that is available
early during the download:
- the device model name (which is a string with vendor and product name
separated by a space)
- the DC_EVENT_DEVINFO 32-bit 'serial' number (which is not necessarily
a real serial number at all, but hopefully at least a unique number
for the particular product)
but because the model name is not necessarily a good filename (think
slashes and other possibly invalid characters), we hash that model name
and use the resulting hex number in the fingerprint file name.
This way the fingerprint file is unambiguous at load and save time, and
depends purely on libdivecomputer data.
But because we also need to verify that we have the actual _dive_
associated with that fingerprint, we also need to save the final
deviceid and diveid when saving the fingerprint file, so that when we
load it again we can look up the dive and verify that we have it before
we use the fingerprint data.
To do that, the fingerprint file itself contains not just the
fingerprint data from libdivecomputer, but the last 8 bytes of the file
are the (subsurface) deviceid and the diveid of the dive that is
associated with the fingerprint.

In commit 4724c88 get_plot_details_new was updated to pass an index
instead of the entry into plot_string. This means we are passing "i" to
plot_string after the final increment of the for loop, instead of
getting the entry[i] within the loop before the final increment. This
means if we are mousing over the far right of the graph, where the time
based break is not hit, we will end up passing an index equal to nr-2
instead of nr-3, which is intended to shave off the final two rows
containing data not useful to the display.
There are a handful of ways to fix this. This commit intends to be
consistent with stylistic choices made elsewhere in the project.
