Dirk's ascii_strtod was blindly copied from other GPL code and didn't do
what was the main purpose (i.e. ignore the locale and still accept the
numbers we have in our data files).
This implementation does *not* care about INF/NaN, and it does *not* try
to handle some strange conditions (overflow/underflow), and I do *not*
guarantee that it doesn't have rounding issues.
That said, for our native format, we never print odd FP numbers anyway
(since we use fixed-point integer arithmetic), and while we *do* care
about exponents for some of the odder import formats (I remember
seeing them in jdivelog output), we don't care about the crazy cases.
So rather than worry about getting the edge cases right for the max
double exponents (around +-308), it just says "screw you" and gives
you something close enough.
So what it *does* try to do is handle the actual parsing right, and
get the right answer for all the reasonable cases.

This patch implements basic functionality to import CSV formatted log
profiles to Subsurface. The import includes time, depth and temperature
from AP Logviewer based on one sample log file I have received. It is
assumed that dive time is the first parameter and depth second.
Temperature is given as a parameter from C source (hard coded currently
to field 15) but we should have a GUI implemented for selecting the
wanted fields.
The two different sample logs of CSV dive log export I have received use
tabulator as field separator. I assume the possible GUI should have
option for the FS as well to be given as parameter to the XSLT.

This data structure was quite fragile and made 'undo' when editing
rather hard to implement. So instead I decided to turn this into a
QMultiMap which seemed like the ideal data structure for it.
This map holds all the dive computer related data indexed by the model. As
QMultiMap it allows multiple entries per key (model string) and
disambiguates between them with the deviceId.
This commit turned out much larger than I wanted. But I didn't manage to
find a clean way to break it up and make the pieces make sense.
So this brings back the Ok / Cancel button for the dive computer edit
dialog. And it makes those two buttons actually do the right thing (which
is what started this whole process). For this to work we simply copy the
map to a working copy and do all edits on that one - and then copy that
over the 'real' map when we accept the changes.

This started out as a way to keep dives in the dive list but being able to
mark them as 'invalid' so they wouldn't be visible (with an option to
disable that feature).
Now it supports an (at this point, fixed) set of tags that can be assigned
to a dive with 'invalid' being just one of them (but one that is special
as it gets some additional support for hiding such dive and marking dives
as (in)valid from the divelist).

divelogs.de sends us XML files that explicitly state that they are in
ISO-8859-1 encoding (which is true). These files contain the HTML encoded
Cyrillic characters. Once we decode those characters the resulting file is
actually UTF-8 encoded (which is a superset of ISO-8859-1). That seriously
confuses libxml when it tries to parse things.
So instead recognize divelogs.de files and skip the encoding declaration
for them before decoding the HTML encoded non-ISO-8859-1 characters.
This does show, however, that divelogs.de incorrectly truncates the
encoded strings (at least in some sample data that I created the parsing
throws errors because of that).

Seems that DM4 has useless cylinder size data on global level and real

global un-used value.
Similarly the DiveMixture table contains cylinder pressures. However, it
appears this information is available on DiveMixture table only in some
cases. So we use start and end pressures from DM table if available,
otherwise we use the global pressures. (My guess is that the DM table
has the pressure info only when the pressure has dropped from the
initial pressure reading that is reported in Dive table before the dive
is considered to have started.)

Localization could be causing floating point numbers to have a comma
instead of a decimal point (in a file format that is really stupid).
If we detect this we replace the comma with a decimal point instead, and
try to re-parse the number, and see if we get further.
The downside of that is that we're changing the buffer we get passed in.
Nobody cares, but still, it's kind of ugly. It's simple, though.

Testing the Planner in Subsurface on a Windows XP SP3 installation,
shows corrupted UTF-8 strings in the case of Cyrillic locales, but
possibly others as well. Instead limited to the Planner, this affects
the entire application.
After some examination it appears that <ctype>'s isspace() in MSVC
on the tested version of Windows is broken for some UTF-8 characters,
after enabling the user locale using: setlocale(LC_ALL, "");
For example, characters such as the Cyrillic capital "BE" are defined as:
0xD091, where isspace() for the first byte returns 0x08, which is the
bytemask for C1_SPACE and the character is treated as space.
After a byte is treated as space, it is usually discarded from a UTF-8
character/string, where if only one byte left, corrupting the entire
string.
In Subsurface, usages of string trimming are present in multiple
locations, so to make this work try to use GLib's g_ascii_isspace(),
which is a locale agnostic version of isspace().
Affected versions of Windows could be everything up to XP SP3,
but not apparently Vista.

Since the temperature profile is binary data, we most likely should

A couple of these could clearly cause a crash just like the one fixed by
commit 00865f5a1e1a ("equipment.c: Fix potential buffer overflow in
size_data_funct()").
One would append user input to fixed length buffer without checking.
We were hardcoding the (correct) max path length in macos.c - replaced by
the actual OS constant.
But the vast majority are just extremely generous guesses how long
localized strings could possibly be.
Yes, this commit is likely leaning towards overkill. But we have now been
bitten by buffer overflow crashes twice that were caused by localization,
so I tried to go through all of the code and identify every possible
buffer that could be affected by this.

Commit 28aba5a206 ("Flesh out the UDDF xml parsing a bit more")
improved on parsing UDDF files by teaching "percent()" to also handle
pure fractions like UDDF uses. So in a UDDF file, an o2 value of "1.0"
means "100%".
But it turns out that I have a few dives with "1% He", and the "Turn
fractions into percent" logic also turns that into 100%.
So this makes the 'percent()' function a bit smarter. If it actually
finds a percentage-sign after the number, it knows it is already
percent, not a fraction. That disambiguates the two cases: "1.0" is
100%, but "1.0%" (note the explicit percentage sign) is 1%.
So now our native format cannot get confused, because it generally
tries to avoid naked numbers. Good choice.

This uses the example UDDF file from Jan Schubert's Heinrichs Weikamp
DR5 dives, and now parses the dive dates, the cylinder mixes and the gas
switch events correctly (or at least partially).
It's not perfect: the gas mix has an "id" field that we ignore, and
instead we just depend on the cylinders being in order (which they seem
to be). And I have rather limited test-cases, so maybe something else
is messed up too. But for the six example dives I have, this gives
reasonable data.

They happen for CDATA content, where libxml2 turns the CDATA fields into
a child of the parent entry, but without a name.
Now, of course, any sane person would just want to use the CDATA as the
string value of the parent itself, but libxml2 probably does this
insanity for a reason. And the reason is probably that some misguided
people want to *write* XML using libxml2, and then the stupid child node
actually acts as a "now I want you to write this data as CDATA".
Whatever the reason, let's just ignore it. We will just traverse such a
nameless child and be happy, and we'll give the nameless child the name
of the parent. Our XML node matching logic will then never see this
insane nameless child at all, and doesn't have to care.
Our whole XML parsing rule-of-thumb is to take the whole "be strict in
what you output, but generous in what you accept" to its logical
conclusion. Because we will literally accept almost anything, in any
format. You can mix tags or attributes wildly, and youc an use CDATA or
not as you see fit. We just don't care.
