I don't know how I was not shot regarding on how broken the
old behavior was.
The new behavior:
1 copy the old_dive_site on top of the current_dive_site
only if the current_dive_site was actually a new uuid,
created by that method.
2 if the current_dive_site is an existing one but it doesn't
have gps coords, copy only the gps coords.
This fixes existing dive sites copying notes and coordinates
from the old_dive_site.

The old backend was less safe because, it didn't:
- support UTF-16 paths!
- use GetUserNameW()
The following changes were made:
- system_default_path_append() can be used to retrieve a path in the user
Roaming path.
- system_default_directory() - this is equal to
system_default_path_append(NULL)
- system_default_filename() also uses the helper

The purpose of testing against known Subsurface runtimes is to warn (when test
is run in verbose mode) if the runtime has altered. Before the next release, we
should update the known Subsurface runtimes to match current behaviour, so we
are alerted when we change something during the next release cycle.

When just assigning one structure to the other we copy the string
pointers. If we then modify those strings in the copy, we happily free
the strings of the original. And then resetting the preferences equally
happily reused those strings, pointing to long since freed memory.
I think what I did now is excessive for the current use case in that it
copies a ton of strings that are unset in the default_prefs. But I figured
this is a rarely used function and I might as well do it correctly.
Also, once we implement multi user support with per user preferences we
will be copying completely populated preferences around (at least that's
my guess).

Because of the way that the webservice userid can be saved both in the
preferences and in a data file it was treated differently than other
preferences settings - which prevented the reset of the preferences from
actually clearing it.
This patch makes sure that if the preferences are reset the preferences UI
reflects that. To make this work the data file loading functions can no
longer be allowed to just simply clear out the userid preference value
just in case they might load a new one.

If the user has no default filename set and starts Subsurface without a
filename, the directory that is opened with Save as ends up being the
current working directory of the executable, which might be its
installation directory - which in general is not a good place to save data
files to.
With this change we pick the directory which is usually used for the
default file, which should give us reasonable places on all OSs.

If so, some formatting chars (like "\n") will be dropped while parsing.
This could be pretty annoying for a user who tries to keep notes other
than a simple text, e.g. if the site is a wreck, may be interesting to
have some data shown like:
...
Max. Depth = 60 m
Min. Depth = 40 m
Prow: bla, bla, bla.
Stern: bla, bla, bla.
...
instead of a single text line.

If the dive computer tells us that this was free diving we should be a lot

Oops. Moving the check to the beginning of the function in order to avoid
partial execution in commit 69036a1bb7 ("Avoid resource leak by bailing
early") had a nasty side effect. Since Linus used 'i' both to hold the
dive number and as a loop variable, by moving this to the top of the
function the dive nr was overwritten which caused all kinds of problems.
My bad - but of course you shouldn't mix loop variables with meaningful
variables, either...

So Anton Lundin says that the 32-bit timestamp for the Divesoft Freedom
is indeed a signed offset from Jan 1, 2000.
This does that, but also extracts the whole thing into a helper function
and makes sure that there are no overflows at any point by using
"timestamp_t" in the whole series, and all the operations are "obviously
safe" in their types (ie no "unsigned char gets widened to 'int' and
then we shift it left by 24 bits").

Commit 31fb2e4c62 ("Avoid possible sign extension") handled the
problem when a "unsigned char" is shifted 24 bits left, and becomes a
"signed int". By casting the result to uint32_t, that signed case won't
happen.
However, there were two bugs in that fix.
The first is the comment. It's not that "timestamp_t" is signed that is
the problem. No, the problem is inherent in the C expression
(ptr[11] << 24)
where "ptr[11]" is an unsigned char. In C arithmetic, unsigned char is
implicitly type-expanded to "int", so while it has a value between
0..255, when you shift it left by 24, you can get a *negative* "int" as
a result.
So it's actually "ptr[11]" that should have been cast to "unsigned", but
it so happens that you can do all the shifting and adding in "int", and
then cast the end result to "uint32_t" and you'll get the same value.
But at no point did "timestamp_t" matter.
The other bug was pre-existing and just not fixed. When the code does
the "+ 946684800" (to turn the timestamp to be seconds from the start of
2000, into seconds since the "unix epoch", ie 1970) that arithmetic is
now done in that "uint32_t" (and used to be done in "int").
Which means that the addition can overflow in 32 bits *before* it is
cast to timestamp_t (which is 64 bits).
Admittedly that 32-bit overflow happens a bit later than the sign bit
gets set, but if we're worried aboout overflows, let's just do this
right.
In other words, we have a 32-bit unsigned offset since Jan 1, 2000, and
for the full range we need to do the epoch correction in 32 bits.
Because otherwise you fail in the year 2106 (32-bit unsigned unix epoch
time limit), even though the 32-bit seconds *should* work all the way
until the year 2136.
Of course, I'll be rather surprised if people still use the Divesoft
Freedom in the year 2106. Or rather, I won't be surprised, because I'll
be dead.
But if we think that the signed problem matters (in the year 2068), then
dammit, we can extend it another 30 years.
