To include the device code in the undo system, we need functions
to check for the existence of devices and to add or remove them.

If we want to avoid the parsers to directly modify global data,
we have to provide a device_table to parse into. This adds such
a state and the corresponding function parameters. However,
for now this is unused.
Adding new parameters is very painful and this commit shows that
we urgently need a "struct divelog" collecting all those tables!

The interaction of Qt's drag & drop with GroupedLineEdit was
exceedingly weird. The user was able to scroll the viewport
making the text invisible.
This implements a very primitive alternative drag & drop
functionality: dropped text is regarged as a distinct tag.
This means that it is not possible to modify existing tags
by dropping in the middle of them. Arguably, this might even
be better than arbitrary drag & drop. But even if not perfect,
this fixes a very nasty UI behavior.

If the user manages to "scroll" through the QPlainTextEdit by
a drag&drop action, the state of the widget becomes inconsistent.
On the one hand, the text-block says that it has one line.
On the other hand, its layout says that it has no line.
When trying to fetch the line, a crash occurs.
Try to detect such a strange state and return early in
GroupedLineEdit::paintEvent().

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.

Apparently libdc gives us copies of strings. The API is very
scary, because (at least according to my reading of the code),
the key/value pair may be stored in a cache. Thus on free()ing
the string in the cache becomes invalid and we must not access
it twice. Very obscure.

When importing dive-sites we would add to the global filter-preset
table. This data should be thrown away, just like the other tables
that might be imported.
This shows that we really should introduce a "struct divelog",
which collects all those tables into a single structure.

We used a typedef "filter_preset_table_t" for the filter preset table,
because it is a "std::vector<filter_preset>". However, that is in
contrast to all the other global tables (dives, trips, sites) that we
have.
Therefore, turn this into a standard struct, which simply inherits
from "std::vector<filter_preset>". Note that while inheriting from
std::vector<> is generally not recommended, it is not a problem
here, because we don't modify it in any shape or form.
Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
filter_preset_table_t was defined as "void" for C code.
However, that meant that any pointer could be passed as
such a table and such a table could be passed as any pointer,
without generating compiler warnings.
Indeed, we had a parameter-mixup that went unnoticed.
Therefore, make filter_preset_t an anonymous structure with
the name filter_preset instead.

The code in core/libdivecomputer.c used string insensitive
comparison for device models, before being merged into core/device.c.
Let's reinstate that behavior, since it appears to be more logical.
On would assume that two different vendors will not use the same
model with different casing (and the same device-ids), so that
should be safe.
This uses strcoll to correctly sort unicode, which will hopefully

To search for devices with the same model, we used find_if().
However, that was only to check whether such a thing exists,
not to actually do something with said device.

We have a callback for all devices with a twist: it can loop
over those devices that are used by a selected dive. This is
used for exporting a subset of the dive log.
Factor out the "is device used by selected dive" part of the
function and make it available to C. The goal is to make
the whole callback thing unnecessary and let C code loop
directly over the device list.

The function getDCExact() was used to search for a device structure

Up to now, "struct device" and "struct device_table" were C++
only, because they used C++ strings for convenience. Since we
switched from QString to std::string, we can create accessors
for these structs. For the C code, we simply declare them as
opaque structs and give the full definition only for C++.

struct device is a core data structure and therefore shouldn't use QString.
QString stores as UTF-16 (which is a very questionable choice in itself).
However, the real problem is that this puts us in lifetime-management
hell when interfacing with C code: The UTF-16 has to be converted to
UTF-8, but when returning such a string, this puts burden on the caller
who has to free it. In fact, instead of looping over devices from C-code
we had a callback that sent down temporary C-strings with qPrintable.
In contrast, std::string is guaranteed to store its data as
contiguous null-terminated and C-compatible strings. Therefore,
replace the QString by std::string. Keep the QString just in
one place that formats a hexadecimal number to avoid any
potential change.
The disadvantage of using std::string is that it will crash
when constructed with a NULL argument, consistent with C-style
functions such as strcmp, etc. Arguably, NULL is different
from the empty string even though we treat both as the same.

Recently (c9b8584bd2) the sort criteria of the device-table
was changed from (model/id) to (id/model). However, that
messed with the detection of duplicate device names: there,
the code searched for the first element greater or equal
to (model / 0).
With the reversal of the sort criteria, this would now
always give the first element.
Therefore, do a simple non-binary search, which is much
more robust. The binary search was a silly and pointless
premature optimization anyway - don't do such things
if not necessary!
Since only one place in the code search for existence
for a model-name, fold the corresponding function into
that place.
Moreover, change the code to do a case-insensitive compare.
This is consistent with the dc_match_serial() code in
core/libdivecomputer.c, where matching models is
case-insensitive!

The device table is accessed by core via a callback using
call_for_each_dc(). This sorts the table by device-id. It
is unclear whether this is needed - since currently all it
does is make sure that the devices have a fixed order in XML
and git log files.
In any case, this means that the table had to be copied and
sorted in call_for_each_dc(). Since the frontend now does
its own sorting, we can just keep the core table sorted
as it needs it. This in turn will ultimately make it possible
to replace the callback by a simple loop.
