The old code was leaking memory. Use std::unique_ptr<> for
ownership management.
This is still very primitive and divetags are kept during
application lifetime. There should probably be some form
of reference counting. And the taglist should not be global,
but attached to the divelog.

Add 'Country' to the fields that are indexed for fulltext search - this
seems to be a quite intuitive choice as 'Country' is also a field that
is available in the dive list view.
Fixes#4134.

Mostly irrelevant std::move() stuff of copy-on-write Qt objects,
a few real bugs, a timestamp_t downconversion and some codingsyle
adaptation.

The parser API was very annoying, as a number of tables
to-be-filled were passed in as pointers. The goal of this
commit is to collect all these tables in a single struct.
This should make it (more or less) clear what is actually
written into the divelog files.
Moreover, it should now be rather easy to search for
instances, where the global logfile is accessed (and it
turns out that there are many!).
The divelog struct does not contain the tables as substructs,
but only collects pointers. The idea is that the "divelog.h"
file can be included without all the other files describing
the numerous tables.
To make it easier to use from C++ parts of the code, the
struct implements a constructor and a destructor. Sadly,
we can't use smart pointers, since the pointers are accessed
from C code. Therfore the constructor and destructor are
quite complex.
The whole commit is large, but was mostly an automatic
conversion.
One oddity of note: the divelog structure also contains
the "autogroup" flag, since that is saved in the divelog.
This actually fixes a bug: Before, when importing dives
from a different log, the autogroup flag was overwritten.
This was probably not intended and does not happen anymore.

The liter symbol is written as 'ℓ'. To allow searching for
that, normalize unicode strings to their base letter. This
corresponds to the 'compatibility' mode.
We might also think about stripping diacritics.

In general, replace "dive master" by "dive guide".
However, do not change written dive logs for now. On reading,
accept both versions.

When importing a divelog, import filter presets. If there are
equal names, import only if the presets differ. In that case,
disambiguate the name. This made things a bit more complicated,
as comparison of filter presets had to be implemented.

So far, the fulltext-query structure only saves an canonicalized
upper-cased version of the query. However, if we want to save the
fulltext query to the log (filter presets) or want to restore an old
fulltext query, we have to store the original query. We don't want
to confront the user with the mangled upper-cased version.
Therefore, also save the original version.

get_cylinder(d, i) is more readable than d->cylinders.cylinders[i].
Moreover, it does bound checking and is more flexible with respect to
changing the core data structures. Most places already used this accessor,
but some still accessed the cylinders directly.
This patch unifies the accesses by consistently switching to get_cylinder().
The affected code is in C++ and accesses the cylinder as reference or
object, whereas the get_cylinder() function is C and returns a pointer.
This results in funky looking "*get_cylinder(d, i)" expressions.
Arguably still better than the original.

When initializing the fulltext-cache and the dive-list, every
100 dives a notification was shown. I had a feeling that this
made startup significantly slower, but that could have been
purely psychological.
Therefore I measured and indeed, removing the fine-grained
notification, it becomes *significantly* faster. For a 3500
dives test log with mobile-on-desktop:
Initialization of the fulltext: 1350 ms -> 730 ms (-46%)
Initialization of the divelistmodel: 689 ms -> 113 ms (-83%)
Let's remove the fine-grained notification. There *is* a visual
indication of work-in-progress anyway.

This function was not meant to be called with already existing data.
However, if it was, it cleared the words without clearing the fulltext
caches of the dives. This lead to crashes.
Be more resilient by not clearing the words: Already existing dives
are unregistered during the process of populating anyway. So this
now *should* work if new dives are added to the dive list and then
this function is called.

This function was named improperly: it was only used on freshly
loaded data. Indeed, attempts to use it to actually reload lead
to crashes.

Add code that indexes all words of a dive and provides searching
for words.
A query is represented by the FullTextQuery class, which can be
initialized by assigning a string to it. It is basically a list
of words.
The result of a search is stored in the FullTextResult class,
which is a list of dives.
The actual indexing and searching is implemented in the FullText
class. However, this class is not exported because the interface
is partially accessible to C. Notably, the reloading of the
fulltext index is done from the C core.
Currently, the indexing and searching is totally unoptimized.
In a ~4000 dives test-log searches typically took single-digit
ms times. There is ample room for optimization (e.g. when
searching for multiple words, chose the words with few dives
first and when down to a few dives, check them individually).
The words of each dive are tokenized and uppercased and
cached with the dive. A pointer to these words is stashed
in the dive structure.
For now, compile only on desktop.
