Move the find-moved-images functions into a new translation unit
and present the user with the identified matches before applying
them.

In the last commits, the canonical-to-local filename map was made
independent from the image hashes and the location of moved images
was based on filename not hashes. The hashes are now in principle
unused (except for conversion of old-style local filename lookups).
Therefore, remove the hashes in this commit. This makes addition
of images distinctly faster.

Users might have edited their pictures. Therefore, instead of identifying
pictures by the hash of the file-content, use the file path. The match
between original and new filename is graded by a score. Currently, this
is the number of path components that match, starting from the filename.
Camparison is case-insensitive.
After having identified the matching images, write the caches so that they
are saved even if the user doesn't cleanly quit the application.
Since the new code uses significantly less resources, it can be run in a
single background thread. Thus, the multi-threading can be simplified.

The connection canonical filename to local filename was done via
two maps:
1) canonical filename -> hash
2) hash -> local filename
But the local filename was always queried from the canonical filename.
Therefore, directly index the former with the latter.
On startup, convert the old map to the new one.

When adding a picture to a dive, cache_picture() was called, which
calculated the hash of the picture in a background-thread.
This made tests occasionally fail, because the tests depended on
the filename-to-localfilename being overwritten in a call running
in a different thread. Depending on which thread finished first,
the test succeeded or failed.
The easiest way to circumvent this problem is to remove the cache_picture()
call. The hash will be calculated anyway with the thumbnails. And
the only function of the hash is the "find moved images" function. Which
is not an issue here, because the user just loaded the images from
disk.

helpers.h included qthelper.h and all functions declared in helpers.h
were defined in qthelper.h. Therefore fold the former into the latter,
since the split seems completely arbitrary.
While doing so, change the return-type of get_dc_nichname from
"const QString" to "QString".

In imagedownloader.cpp the only thing we need from the picture struct
is the filename. Therefore, use QStrings instead of the picture struct.
This simplifies memory management.
Remove the clone_picture() function, which is not needed anymore.

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.

qthelper.cpp is already quite voluminous. Move the recently
introduced localized versions of (v)snprintf() and put_format()
into their own translation unit.
Moreover, adopt C-style semantics for asprintf_loc(). This function
will be used to remove fixed-size buffers in core/plannernotes.c.

Previous taglist_get_tagstring signature/implementation did not allow
handling of cases where inputted buffer could not contain all tags.
New implementation allocates buffer based on pre-computed size allowing to
insert all tags in the returned string.
Added get_taglist_string in qthelper to handle conversion to QString
Added TestTagList with tests for taglist_get_tagstring

occurrences that they seem worthy of a short helper-function.

The hash field in the picture-structure was in principle non-operational.
It was set on loading, but never actually changed. The authoritative
hash comes from the filename->hash map.
Therefore, make this explicit by removing the hash field from the
picture structure.
Instead of filling the picture structure on loading, add the
hash directly to the filename->hash map. This is done in the
register_hash() function, which does not overwrite old entries.
I.e. the local hash has priority over the save-file. This
policy might be refined in the future.

Passing of QStrings and QByteArrays was inconsistent in qthelper.cpp.
Unify to passing const-references. Passing by value is no big deal, since
QString and QByteArray do copy-on-write "optimization". Nevertheless, let's
keep it as consistent and effective as possible.

learnHash() was always called in conjunction with add_hash(). The
pattern was that a local filename and a hash were connected in
the hash-to-filename and the filename-to-hash maps. Then, the
original picture-filename or url were registered in the filename-to-hash
map.
This commit changes learnHash() to take three parameters (original-filename,
local-filename and hash) and do all of the above. The new code is
simpler because no dummy picture struct has to be generated in
DiveListView::loadImageFromURL().
The tests were extended to check for all hash<->filename associations.

learnHash() is called either on a local picture structure
[DiveListView::loadImageFromURL()] or on a cloned picture structure
[ImageDownloader::saveImage()]. In neither case the picture structure
is passed to the frontend. Therefore, storing the new hash in the
picture struct is not necessary.

This commit introduces functions:
- QString asprintf_loc(const char *cformat, ...);
- int snprintf_loc(char *dst, size_t size, const char *cformat, ...);
- put_format_loc(struct membuffer *, const char *fmt, ...);
and their va_arg equivalents, which use Qt's QString::arg() formatting
options to render the strings.
The snprintf_loc() function takes care not to truncate multi-byte
UTF-8 encodings. Thus, on overflow, the resulting string might be
shorter than size-1.

Since all qt-helpers are defined in qthelper.cpp, there seems to be
no reason to have two include files. By unifying the two files,
duplication and inconsistencies are removed. The C++-only part is
simply compiled away with #ifdefs.

For UI responsiveness, we need to be able to run the planner in the background. This needs the
planner state to be localized (and we need to pass a pointer around).
In order to not let too many lines overrun (and to save typing in the future)
I have renamed instances of struct deco_state to ds. Yes this should have gone
to a separate commit but I accidentally commit --amend'ed it.
Computing of planner variations is temporarily disabled.
Unlock the planner when returning early
So we don't deadlock in add dive and recreational mode (which
use the planner without actually planning).

Moving the GUI independent Seabear import functionality to Subsurface
core. This will allow Robert to call it directly from download from DC.
Tested with H3 against released and daily versions of Subsurface. The
result differs somewhat, but it is actually fixing 2 bugs:
- Temperature was mis-interpreted previously
- Sample interval for a dive with 1 second interval was parsed
incorrectly

We have two prefernces determining the deco_mode (BUEHLMANN vs VPMB
vs RECREATIONAL): One for the planner (deco_mode) and one for
displaying dives (display_deco_mode). The former is set in the planner
settings while the latter is set in the preferences.
This patch clears up a confusion which of the two to use by introducing
a helper function that selects the correct variable.

Determining the correct cylinder index from a known gas mix can be
complicated, but it is trivial to look up the gasmix from the cylinder_t
structure.
It makes sense to remember which cylinder is being used. This simplifies
handling changing a cylinder's gas mix, either directly by the user, or
indirectly in the planner. It also permits tracking of multiple cylinders of
the same mix, e.g. independent twins / sidemount.

Having subsurface-core as a directory name really messes with
autocomplete and is obviously redundant. Simmilarly, qt-mobile caused an
autocomplete conflict and also was inconsistent with the desktop-widget
name for the directory containing the "other" UI.
And while cleaning up the resulting change in the path name for include
files, I decided to clean up those even more to make them consistent
overall.
This could have been handled in more commits, but since this requires a
make clean before the build, it seemed more sensible to do it all in one.
