C-style memory management is a pain and nearly nobody seems to get
it right. Add a C++-version of membuffer that frees the buffer
when it gets out-of-scope. Originally, I was thinking about
conditionally adding a constructor/destructor pair when compiling
with C++. But then decided to create a derived class membufferpp,
because it would be extremely confusing to have behavioral change
when changing a source from from C to C++ or vice-versa.
Also add a comment about the dangers of returned pointer: They
become dangling on changes to the membuffer.

The application state is a desktop-only thing. The mobile UI
also has its application state, but that is something completely
different.
The last remaining user of the application state was to flag
whether the planner is active. Since this has all been
unglobalized, the ApplicationState structure can be moved
from core to the desktop UI. And there it can be made local
to the MainWindow class.

Since dive.c is so huge, split out divecomputer-related functions
into divecomputer.[c|h], sample.[c|h] and extradata.[c|h].

dive.h has to include divecomputer.h. However, it make things

The XML-parameter code is a mess. Ownership is unclear. Allocation
and freeing of strings is in different functions. Sometimes
only every second string is free()d, because keys are not copied.
But this is done inconsistently. The caller has to know how
many parameters the callee may add.
Instead, let's add a small helper-struct that uses C++ memory
management, but exports a C-API. The array for the XML-library
is generated on the fly.
This is only the implementation, the old code is not yet replaced.

Add a rudimentary list of filter presets to the core. The list
is sorted by name. Access is provided via a C interface so that
the presets can be written to the git and XML logs. Internally,
the list is realized by a C++ vector for convenience (euphemism for
laziness).
Morover, a C++ interface is provided for the UI. Currently names of
the presets cannot be edited, since this would mean that the order
of the list changes. This may be implemented later if required.

Adds a filter constraint object to the core, which represents one
constraint the user can filter dives with. The plan is to write these
constraints to the XML and git logs. Therefore, this code is written
in C-style except when it comes to handling strings and dates, which
is just too painful in plain C.
There is one pointer to QStringList in the class, though when compiled
with C, this is simply transformed into a pointer to void. Granted,
that smells of an ugly hack. However it's more pragmatic than
self-flaggelation with C string and list handling.
A filter constraint is supposed to be a very general thing, which can
filter for strings, multiple-choice lists, numerical ranges and date
ranges.
Range constraints have a range mode: less-or-equal, greater-or-equal
or in-range. Text constraints have a string mode: startswith, substring
or exact.
All the data are accessed via setter and getter functions for
at least basic levels of isolation, despite being written with
a C-interface in mind.

core/device.h was declaring a number of functions that were related
to divecomputers (dcs): creating a fake dc for manually entered dives
and registering / accessing dc nicknames. On could argue whether
these should be lumped together, but it is what it is.
However, part of that was implemented in C++/Qt code in a separate
core/divecomputer.cpp file. Some function therein where only
accessible to C++ and declared in core/divecomputer.h.
All in all, a big mess. Let's simply combine the files and
conditionally compile the C++-only functions depending on
the __cplusplus define.
Yes, that means turning device.c into device.cpp. A brave soul
might turn the C++/Qt code into C code if they whish later on.

Dives for the seac action computer are imported by the seacsync
program into two tables in an sqlite3 database.
The dive information is read from the headers_dive table.
The dive_data table is then queried for each dive to get samples.
The seac action computer is the only current supported computer
by the seacsync program. It only supports two gas mixes, so the
parser will toggle between two cylinders whenever it detects a
change in the active O2 mix.
Dive start time is stored in UTC with a timezone offset.
A helper function to read this was added to qthelper.
Default cases have been added to some switch statements
to assist in future development for other dive types and
salinity.

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.

The application state was encoded in a QByteArray. Thus, there was
no compile-time checking. Typos would lead to silent failures.
Turn the application state into an enum. Use the enum-class construct,
so that the values don't polute the global namespace. Moreover,
this makes them strongly typed, i.e. they don't auto-convert to
integers.
A disadvantage is that the enums now have to be cast to int
explicitly when used to index an array.
Replace two hash-maps in MainWindow to arrays of fixed sizes.

Previously, each dive-list modifying function would lead to a
full model reset. Instead, implement proper Qt-model semantics
using beginInsertRows()/endInsertRows(), beginRemoveRows()/
endRemoveRows(), dataChange().
To do so, a DiveListNotifer singleton is generatated, which
broadcasts all changes to the dive-list. Signals are sent by
the commands and received by the DiveTripModel. Signals are
batched by dive-trip. This seems to be an adequate compromise
for the two kinds of list-views (tree and list). In the common
usecase mostly dives of a single trip are affected.
Thus, batching of dives is performed in two positions:
- At command-level to batch by trip
- In DiveTripModel to feed batches of contiguous elements
to Qt's begin*/end*-functions.
This is conceptually simple, but rather complex code. To avoid
repetition of complex loops, the batching is implemented in
templated-functions, which are passed lambda-functions, which
are called for each batch.

XMP is a media-metadata standard based on XML which may be used
across a variety of media formats. Some video-processing software
writes XMP data without updating the native metadata fields.
Therefore, we should aim at reading XMP metadata and give priority
of XMP data over native fields.
Pros:
- Support for *all* common media formats.
Cons:
- XML (complex, verbose, chaotic).
- Does not even come close to fulfilling its promise of being
well defined (see below).
Implement a simple XMP-parser using libxml2. Connect the XMP-parser to
the existing Quicktime/MP4 parser.
First problem encountered: According to the spec, XMP data supposed
to be put in the 'XMP_' atom. But for example exiftools instead
writes an 'uuid' atom with a special 16-byte uid. Implement both,
more options will probably follow.
Second problem: two versions of recording the creation date were found
1) The content of a <exif:DateTimeOriginal> tag.
2) The xmp::CreateDate attribute of a <rdf:Description> tag.
Here too, more versions are expected to surface and will have
to be supported in due course (with an obvious priority problem).
