ec431155a9 filter: implement filtering for gas mixes
This adds filter constraints for numerical filtering for gas-mixes.
Currently, this does a "match any" kind of search, which means that
a dive is filtered if any of its cylinders matches.

We should also implement "all-of" and "none-of" modes for cylinder
filtering.

23da23a534 core: add N2 and general gas component accessors
There were helper functions to access O2 and He component fractions.
Add another one for N2. Indeed, this can be used in three cases, where
N2 was deduced indirectly.

Moreover, add a general accessor with a gas_component argument.
This will be used by the filter code to filter for gas components.

cd22b86bf8 dive list: when moving dives, delete first and add later
When moving dives between trips, the core moves the dives internally
and sends a signal to the model. The model adds and removes the dives
accordingly. However, when adding the new dive, the old trip hasn't
changed its position, so the ordering is wrong leading to an inconsistent
state.

Therefore, remove the dives first and then readd them. There could
still be pathological cases where this fails. However, in the short
term this is an improvement. Note that in similar cases, the dives were
indeed removed then added, so this case here seems to be an oversight.

7b196a5ef9 desktop: allow moving dives to arbitrary trips
The UI only allowed adding dives to trips above or below the
current dive (and even that is buggy). This is a strange
restriction, since trips are designed to be non-contiguous.

Allow adding dives to any trip using the new trip selection

d8f35711ff membuffer: be defensive about bad C library vsnprintf implementations
Dirk reports that some Windows users have had odd corruption in the
commit messages in the cloud storage.  They make no sense at all unless
there is some very weird Windows library bug.

The prime suspect is 'vsnprintf()' returning a negative error when the
target buffer is too small (rather than the proper "this is how much
space it would need").  That is a very traditional C library bug that I
thougth had been fixed everywhere, but there doesn't really seem to be a
lot of other likely causes.

So let's make our membuffer code be defensive against bad libraries that
return negative error numbers from vsnprintf.

4608beaee4 Android BLE discovery: use discovery agent
Android can't scan for classic BT devices, so when BT support was first
added, we simply didn't use the discovery agent at all and relied on the
list of paired BT devices provided by Android.

This still worked fine for a lot of BLE devices that allowed 'bonding'
with the Android device - similar to pairing. But some BLE devices (like
the Shearwater Peregrine) don't support bonding and so our Android code
didn't see them at all.

With this commit we start a BLE only scan on Android to add to the list
of already paired devices.

3bfd448b59 filter: implement saving of filter presets to git repositories
On the mailing list it was decided that users might want to
move their filter presets across computers via the cloud.
Notably, in the future one might access statistics on mobile and
these might by controlled by filter presets.

The git save routines use the same string formatting as the
XML save routines. The string formatting is found in
core/filterconstraint.cpp. Thus, duplication of code and
inconsistencies should be minimized.

Each filter preset is saved into a file in the "02-Filterpresets"
folder in the root of the git repository.

Each file consists of one "name" line, zero or one "fulltext" line
and zero or more "constraint" lines.

The modes, types and the actual payload is controlled via attributes.
Thus, a preset file might look like this:

name "test"
fulltext mode="substring" query="clown"
constraint type="location" stringmode="starstwith" data="mafia"
constraint type="sac" rangemode="range" negate data="5000,10000"

41cf83583d filter: load filter presets from XML files
This is a bit painful: since we don't want to modify the filter
presets when the user imports (as opposed to opens) a log,
we have to provide a table where the parser stores the presets.
Calling the parser is getting quite unwieldy, since many tables
are passed. We probably should introduce a structure representing
a full log-book at one point, which collects all the things that
are saved to the log.

Apart from that, this is simply the counterpart to saving to XML.
The interpretation of the string data is performed by core
functions, not the parser itself to avoid code duplication with
the git parser.

448bc5600b filter: implement saving of presets to XML file
Users might want to move their presets with there log-file. Therefore,
save the presets to the log. The alternative would be to save them
to the preferences. However, on the mailinglist it was decided that
moving the presets to a mobile device is a wanted feature.

The XML saving code has a rather reasonable interface, therefore
this turned out to be pretty easy to implement.

The filter presets are saved into a
<filterpresets>
 ...
</filterpresets>
block

Each individual preset is saved into a
 <filterpreset name='...'>
    ...
 </filterpreset>
Block with a unique name attribute.

Each preset contains zero or one fulltext and zero or more constraint entries.
The type and mode(s) are controlled by attributes, the "payload" is saved in
the block. Note that all the formatting is done by functions in core/filterconstraint.c
and not the parser itself.

A preset in the XML file might look like this:

 <filterpreset name='test1'>
  <fulltext mode='startswith'>Train</fulltext>
  <constraint type='planned'>0,0</constraint>
  <constraint type='sac' range_mode='range' negate='1'>5000,10000</constraint>

634152ae43 filter: add filter constraint object to the core
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.
