The string code of uemis-downloader.cpp was broken in more ways
than can be listed here. Notably, it brazenly refused to free any
memory allocated for the parameters buffer.
Using std::string and std::string_view should plug all those
memory holes. That made it necessary to do some major refactoring.
This was done blind and therefore will break.

newmax was an integer variable kept as a string. Very ominous.
Moreover, memory management seems to be broken:
1) The string is never freed.
2) The string is passed as value from do_uemis_import() to
get_matching_dives(), which passes it as reference to
process_raw_buffer(), which may reallocate it, which means
that do_uemis_import() now possesses a pointer to a free()d
string.
Simplify all that by making newmax an integer variable and
passing it as a reference from do_uemis_import() to
get_matching_dives().

There were a number of fprintf()s that escaped the conversion
to report_info(), because they used "debugfile" instead of
"stderr" as target. However, debugfile was just #defined to
be stderr, so we might just use report_info() for consistency.

The uemis code is wild. It simply doesn't deallocate memory
and uses global variables. To get this under control, create
a "struct uemis" and make the functions exported by "uemis.h"
members of "struct uemis". Thus, we don't have to carry around
a parameter for the state of the importing process.
Turn a linked list of "helper" structures (one per imported dive)
into a std::unordered_map, to fix leaking of the helper structures.

This was very obscure: the function that parses into a struct
dive was passed a void-pointer instead of a struct dive-pointer.
Why? Just pass the correct type.

The SHA1() helper function was only used when calculating a
SHA1 hash and taking the first four bytes of it as uint32.
Make that explicit by renaming the function into SHA1_uint32()
and directly returning an uint32_t.
Note that the usage in cochran.cpp is sketchy: it generates
a four-byte hash out of two-byte data. Why!?

The strtod_flags() function allowed for fine control of how to
parse strings. However, only two different modes were actually
used: ascii mode ("C" locale) and permissive mode (accept ","
and "." as decimal separator).
The former had already its own function name (ascii_strtod).
Make the latter a separatge function as well (permissive_strtod)
and remove all the flags rigmarole.

Owing to bitrot, this union only contained a float and therefore
is pointless. Let's remove it.
That makes the function name "integer_or_float()" non-sensical.
Call it "parse_float()" instead.
Moreover, change the output-arguments of "parse_float()" from
pointers to references, as null-pointers are not supported.
Finally, remove the "errno" check after "ascii_strtod()". As far as
I can tell, errno is not set in "ascii_strtod()" and using a global
variable for error-reporting it is an incredibly silly interface
anyway.

Some improvements:
- for constraints where the condition is applied to any one of a list of
items, show the condition as 'any X';
- when filtering for tags, do not include divemode as a 'tag' - this is
hard to impossible for users to understand, and we do have a dedicated
condition for the dive mode.

Fix loading of the negation of filter conditions. Unlike other
conditions that are persisted as `<key>="<value>"`, this is persisted
to git as `negate`.
This fix remediates this for all cases where the condition has already
been saved to the cloud storage.
Saving to XML takes a different approach and indicates negated
conditions with `negate="1"`, making it identical to all other
attributes. The question is if this approach should be implemented in
addition to the above fix, in order to unify the storage format.

Fix an issue introduced in #4148.
Essentially the refactoring missed the fact that in the imperial system
tank size is tracked as the free gas volume, but in the metric system
(which is the one used in most of Subsurface's calculations) tank size
is tracked as water capacity.
So when updating a tank template tracking imperial measurements, the
given (metric) volume in l has to be multiplied by the working pressure,
and vice versa.
This also combines all the logic dealing with `tank_info` data in one
place, hopefully making it less likely that this will be broken by
inconsistencies in the future.
Fixes#4239.

- show the correct gasmix in the profile;
- make gases available for gas switches in the profile after they have
been added;
- persist gas changes;
- add air as a default gas when adding a dive.
This still has problems when undoing a gas switch - instead of
completely removing the gas switch it is just moved to the next point in the
profile.

- standardise the naming;
- use it consistently;
- apply the 'samples < 50' only when putting manually added dives into
edit mode - everywhere else manually added dives should be treated as
such;

46cf2fc086 fixed a bug where clearing of a divelog, such as the one
used for import, would erase dives in the global(!) divelog.
However, the new code used the function clear_dive_table(), which
only cleared the table without unregistering the dives. In particular,
the dives were not removed from the trips, which means that the trips
were not free()d.
This reinstates the old code, but now passes a divelog paremeter
to delete_single_dive() instead of accessing the global divelog.
Moreover, delete dives from the back to avoid unnecessary
copying.
An alternative and definitely simpler solution might be to just
add a "clear_trip_table()" after "clear_dive_table()".

Currently editing of planned dives that have been merged with actual
(logged) dives only works if the 'Planned dive' divecomputer is the
first divecomputer, and this divecomputer is selected when clicking
'Edit planned dive'. In other cases the profile of the first
divecomputer is overlaid with the profile of the planned dive, and the
first divecomputer's profile is overwritten when saving the dive plan.
Fix this problem.
Triggered by @SeppoTakalo's comment (https://github.com/subsurface/subsurface/issues/1913#issuecomment-2075562119): Users don't like that planned dives show up as their own entries in the dive list, so being able to merge them with the actual dive after it has been executed is a good feature - but this wasn't working well until now.

The old code was leaking memory. Use std::unique_ptr<> for
ownership management.
This is still very primitive and divetags are kept during
application lifetime. There should probably be some form
of reference counting. And the taglist should not be global,
but attached to the divelog.

Let's use std::string in the core. Notably, I'd like to make
the numerous main() functions mostly independent of Qt. Some
things will have to remain, such as argument parsing, of course.
This changes the API: instead of returning an error code and
taking a pointer to the actual return-value, return an
std::optional<std::string>> that is set if the function succeeds.
Returning an empty string in the error case might be simpler,
but oh well...
