Create a new class, which performs all thumbnailing code.
This is mostly code reshuffling. Thumbnails are extracted
either from a cache or thumbnail calculation is started in
a worker thread.
Since getHashedImage() is called from a worker thread it
makes no sense to call subfunctions in yet another worker
thread. Remove these calls.
In contrast to the previous code, on error the background
thread produces a failure image, but it is not yet shown.

The old code loaded all thumbnails into memory at once. This does
not scale to logs with thousands of pictures. Therefore, save
the pictures to individual files and only load the currently
needed pictures.
Currently, this will make changing switching between dives slower,
because the thumbnails are loaded from disk. In the future, it
is planned to do this in a background thread without blocking
the user interface.
A notable difference to the old code: Thumbnails are now indexed
by the image-hash (i.e. the content of the raw image) and not
by the filename of the image. Thus, different paths to the same
image should only be saved once.

fake_dc() used to return a statically allocated dc with statically
allocated samples. This is of course a questionable practice in
the light of multi-threading / resource ownership. Once these
problems were recognized, the parameter "alloc" was added. If set
to true, the function would still return a statically allocated
dc, but heap-allocated samples, which could then be copied in
a different dc.
All in all an ownership nightmare and a recipie for disaster.
The returned static dc was only used as a pointer to the samples
anyway. There are four callers of fake_dc() and they all have access
to a dc-structure without samples. Therefore, change the semantics
of fake_dc() to fill out the passed in dc. If the caller does
not care about the samples, it can simply reset the sample number
to zero after work.

This commit allows plotting the OC-equivalent pO2 graph for PSCR
dives. This happens in both the cases where there is no external
O2-monitoring AND when there is external pO2 monitoring. The
calculations are only done for PSCR dives and is achieved as
follows:
1) Within plot-info create a pressure-t called OC_pO2 in
profile.h and populate this variable with the open-circuit
pO2 values in profile.c.
2) Create a new partialPressureGasItem ocpo2GasItem in
profilewidget2.h and, in profilewidget2.cpp, initialise it
to read the plot-info OC_pO2 values and enable its
display by using the setVisible method. The
diveplotdatamodel was also touched in order to achieve
this.
3) Create a pref button that controls the display of OC-pO2 for SCR dives
4) Change the colour of the OC-pO2 grpah to orange
5) Change the connection of the crr_OC_pO2 signal to be appropriate
6) rename the OC_pO2 attribute to scr_OC-pO2

See also e6e1473e6. The construction of the locationlist
was not the same as the 3 previous lists, and it needs
the inclusion of a new model file (divelocationmodel.cpp)

interested in a simple stringList (model) to populate a HintsText
field (or maybe later a combobox), this stringlist is added
to the model, to easy interfacing with QML.

This is the first of a set of commits that are (very) similar.
It appeared that a number of more or less static lists, which are
constructed by a loop over all dives in the logbook, were executed
when changing focus to a next dive. For example, the in this
commit addressed list of used dive suits.
What was wrong was that the suitList was linked to a dive. There
is only a need to construct the list of used suits when data is
changed (and obviously, once on startup of the app). Further, it
appeared that a lot of code was duplicated and that we can use
(in this case) the same code from the desktop completionmodels.cpp.
Basically, this commit involves the following changes:
- include completionmodels.cpp in mobile and desktop (so move
it from the desktop only category to the generic category).
- remove double code from DiveObjectHelper.cpp
- Do not differentiate in the init phase and the normal refresh
of the list
- the per dive logic is now only the getting of a previously
constructed list (in init or update of the divelist).
There are no visible changes in the UI, other than a better
performance when scrolling over dive details.

This patch allows the planner to save the last manually-entered
dive planner point of a dive plan. When the plan has been saved
and re-opened for edit, the time of the last-entered dive planner
point is used to ensure that dive planning continues from the same
point in the profile as was when the original dive plan was saved.
Mechanism:
1) In dive.h, create a new dc attribute dc->last_manual_time
with data type of duration_t.
2) In diveplanner.c, ensure that the last manually-entered
dive planner point is saved in dc->last_manual_time.
3) In save-xml.c, create a new XML attribute for the <divecomputer>
element, named last-manual-time. For dive plans, the element would
now look like:
<divecomputer model='planned dive' last-manual-time='31:17 min'>
4) In parse-xml.c, insert code that recognises the last-manual-time
XML attribute, reads the time value and assigns this time to
dc->last_manual_time.
5) In diveplannermodel.cpp, method DiveplannerPointModel::loadfromdive,
insert code that sets the appropriate boolean value to dp->entered
by comparing newtime (i.e. time of dp) with dc->last_manual_time.
6) Diveplannermodel.cpp also accepts profile data from normal dives in
the dive log, whether hand-entered or loaded from dive computer. It
looks like the reduction of dive points for dives with >100 points
continues to work ok.
The result is that when a dive plan is saved with manually entered
points up to e.g. 10 minutes into the dive, it can be re-opened for edit
in the dive planner and the planner re-creates the plan with manually
entered points up to 10 minutes. The rest of the points are "soft"
points, shaped by the deco calculations of the planner.
Improvements: Improve code for profile display in dive planner
This responds to #1052.
Change load-git.c and save-git.c so that the last-manual-time is
also saved in the git-format dive log.

This is a somewhat hacky commit. For a very long time, the delete
from the divelist on mobile crashed. That is, not always for anyone,
but for me almost consistently. This commit tries to solve it.
I found that trying to save the delete immediately after removing
data from the underlying model seemed to cause the crash. Hacking
around, I found that a simple beginResetModel/endResetModel between
the delete of the underlying model data and actual save is
sufficient to solve the crash.
The big question is, why does this all work? I suspect some of race
condition between deleting model data, and giving the QML engine
the opportunity to do its thing.
This is also related to issue #311, but that is not implemented
here.

This is mainly code maintenance. Instead of emitting explicit
dataChanged signals, we can make sure that setStringList()
is called after all model data manipulation is ready. Accoording
to the Qt docs: "The model will notify any attached views
that its underlying data has changed".

better.

This "bug" is found using Qt 5.10 compiled in developer mode. Access
the filers, click a little around here, close the filters. Almost every
time the following assert is triggered:
ASSERT failure in QPersistentModelIndex::~QPersistentModelIndex:
"persistent model indexes corrupted", file itemmodels/qabstractitemmodel.cpp, line 643
This is relatively deep down in Qt, and it is triggered by clearing the
filters. Trying to force a crash when using the same scenario in Qt 5.10
compiled for production (so no active asserts) did not result in a crash.
So, upto this time, it is unclear if the Qt assert points out a real problem,
or it is some false alarm (for whatever reason).
Further investigation shows that the assert can be solved by changing the
invalidate() to an invalidateFilter(). Indeed, the last variant is a little
more lightweigt, and does seem to do the same job from a functional point
of view (in this case).
