std::string is used because parts of the code assumes
that the data is null terminated after the last character
of the data. std::string does precisely that.
One disadvantage is that std::string clears its memory
when resizing / initializing. Thus we read the file onto
freshly cleared data, which some might thing is a
performance regression. Until someone shows me that this
matters, I don't care.

The function clear_*_table frees all elements of the table.
However, persumably as a performance feature, it kept the
memory of the table itselt (i.e. it only reset the number of
elements but kept the capacity).
That is fine if the table is reused later. However, this
function was also used when freeing the table and this
would leak the table memory.
This commit frees the table memory. An alternative would

Currently, the "hide event" status is lost when switching dives.
Save it in the event struct instead to make it persistent.
In the future we might save this information to the log file.
Then this should be integrated in the undo-system.
This commit also makes the "unhide events" menu entry more

events and event types.
Note this adds an additional field to the event structure.
There is a "deleted" field that is used internally for
book-keeping, but probably should be removed. Not touching

There are two enums related to the type of dive.

UNDEF_COMP_TYPE};
and the anonymous
enum {AIR, NITROX, TRIMIX, FREEDIVING} dive_type;

The existing logic correctly calculates the minimum (ie, ending) pressure, but not the maximum

then merged):
A: 205 - 84
B: 83 - 55
When merging the starting pressures, the call is : merge_pressure(205, 0, 83, 0, false)
The final comparison is:
if(false && 205 < 83) return 205;
else return 83;
-> So 83 is returned even though 205 should have been.

Fix how gases are marked as 'used' and kept from being deleted in the
equipment tab for CCR dives.
It does not make sense to treat the (arbitrary) first gas in the list
with a usage type of 'diluent' or 'oxygen' as 'used' and prevent the
user from deleting it. Dive computers report the initial diluent and
any other diluents used through a 'gaschange' event, so the actually
used diluents are already picked up as part of gaschange event based
logic.
Also clarify the selection of the first diluent used as a default if no
gaschange events exist.
Also fixed the test data - gases that have a pressure change should be
included in the profile if they do not have a gas change recorded
against them by other dive computers, even if they are oxygen.
A secondary problem shown by this is that the pressure change is not
applied to the profile - the pressure is currently shown as constant on
the start pressure. But this is for another pull request.
