We should call this function with two well defined dive_or_trip structures
which means that exactly one of the two values is set in each argument. But
in order to not have bugs elsewhere leed to crashes here, be more tolerant
of malformed argumnts.

When clicking "done" on the dive site edit screen, the diveSite
member variable was reset to nullptr in acceptChanges() at the
beginning of the function. This prevented posting an undo-command
as a consequence of the active widget losing focus.
Reset the diveSite variable after exiting dive-site mode, which
causes the active widget to lose focus.

The native buffer of a membuffer is not NUL-terminated, so when you want
to detach it and use it as a C string, you had to first do
'mb_cstring()' that adds the proper termination/
This was all documented in the header files, and all but two users did
it correctly.
But there were those two users, and the exported interface was
unnecessarily hard to use. We do want the "just detach the raw buffer"
internally in the membuffer code, but let's not make the exported
interface be that hard to use.
So this switches the exported interface to be 'detach_cstring()', which
does that 'mb_cstring()' for you, and avoids the possibility that you'd
use a non-terminated memory buffer as a C string.
The old 'detach_buffer()' is now purely the internal membuffer
implementation, and not used by others.

This one is a bit complicated as it depends on a specific flow, but it
seems like setup_cvs_parms might indeed write NULL to the element at
index 49 of parm. I'm not 100% sure that the sequence of events required
for this can happen, but adding one more pointer to the array seems like
cheap insurance.

The profile repainting code that was called when a dive changed was
located in a separate function. Not only did it take a redundant
parameter, it also performed very weird stuff like entering and
exiting plan state. That did not work at all. Replace by a simple
call to plotDive() and things work much better.
There was a comment about DivePlannerPointsModel and profile
getting out of sync. So let's keep an eye out for that.

The divesEdited signal sends the changed field as a parameter.
Since some undo-commands change multiple fields, this led to
numerous signals for a single command. This in turn would lead
to multiple profile-reloads and statistic recalculations.
Therefore, turn the enum into a bitfield. For simplicity,
provide a constructor that takes classical flags and turns
them into the bitfield. This is necessary because C-style
named initialization is only supported on C++20 onward!
Is this somewhat overengineered? Yes, maybe.
