152e6966c9 fix copy/paste of dive-site
The copy/pasting of dive-sites was fundamentally broken in at least two
ways:

1) The dive-site pointer in struct dive was simply overwritten, which
   breaks internal consistency. Also, no dive-site changed signals where
   sent.

2) The copied dive-site was stored as a pointer in a struct dive. Thus,
   the user could copy a dive, then delete the dive-site and paste.
   This would lead to a dangling pointer and ultimately crash the
   application.

Fix this by storing the UUID of the dive-site, not a pointer.
To do that, don't store a copy of the dive, but collect all
the data in a `dive_paste_data` structure.
If the dive site has been deleted on paste, do nothing.
Send the appropriate signals on pasting.

The mobile version had an additional bug: It kept a pointer to the
dive to be copied, which might become stale by undo.

5c7cfb1057 core: replace list of dives in trip by std::vector<>
The dive_table will be converted into a table of owning pointers.
Since the trip has only non-owning pointers to dives, turn
its dive_table into an std::vector<dive *>.

Add a helper functions to add/remove items in a sorted list.
These could be used elsewhere.

f120fecccb core: use std::vector<> to store divecomputer samples
This is a hairy one, because the sample code is rather tricky.

There was a pattern of looping through pairs of adjacent samples,
for interpolation purposes. Add an range adapter to generalize
such loops.

Removes the finish_sample() function: The code would call
prepare_sample() to start parsing of samples and then
finish_sample() to actuall add it. I.e. a kind of commit().

Since, with one exception, all users of prepare_sample()
called finish_sample() in all code paths, we might just add
the sample in the first place. The exception was sample_end()
in parse.cpp. This brings a small change: samples are now
added, even if they could only be parsed partially. I doubt
that this makes any difference, since it will only happen
for broken divelogs anyway.

6b835710bc map: use value semantics for MapLocation
This makes memory management more simple, as not explicit deletion
is necessary.

A rather large commit, because changing QVector<> to std::vector<>
is propagated up the call chain.

Adds a new range_contains() helper function for collection
types such as std::vector<>. I didn't want to call it
contains(), since we already have a contains function
for strings and let's keep argument overloading simple.

a2845ece82 cleanup: use range based for in download code
This removes a constant describing the length of the array.

The enumerated_range code had to be adapted, because the
interaction of C-type arrays with the C++ typesystem is mad.
With C-type arrays, one has to pass a reference to std::declval.

691d9e86de cleanup: implement index_of() and index_of_if() generics
Search the index of an item in a container. Compare by
equality or a lambda. The lack of these have annoyed me for a
long time. Return the index of the first found element or
-1 if no element found.

Currently, only supports random-access operators. Might be
trivially changed for forward iterators.

cea171ffd4 core: implement an enumerating iterator
In the printing-template code, we loop through a vector and
then determine the index of the current element by searching
the vector. This irks me.

Since looping over a collection with an index is a rather
common theme, implement an enumerating iterator that can
be used as in:
	for (auto [idx, item]: enumerated_range(v)) {
		...
	}

For now, use it for the above vexing case. Convert other
iterations of this theme later.

94641c510f core: create range.h header for range manupulation functions
The moveInVector() function was defined in qthelper.h, even
though it has nothing to do with Qt. Therefore, move it into
its own header.

Morover, since it is a very low-level function, use snake_case.
And rename it to move_in_range(), because it does not only
work on vectors, but any range with random-access iterators.
