This is another entry in the series to make more things
"const-clean" with the ultimate goal of merge_dive() take
const pointers.
This concerns functions taking pointers to events and
the fallout from making these const.
The somewhat debatable part of this commit might be
that get_next_event() is split in a two distinct
(const and non-const) versions with different names,
since C doesn't allow overloading. The linker should
recognize that these functions are identical and remove
one of them.

Accessor-functions without noticeable logic, such as depth_to_bar()
can trivially be made "const-clean".
Moreover, let get_dive_location() return a "const char *". The
non-const version must have been an oversight, as the caller
must not free() or overwrite the string.

In a previous commit, the get_gasmix_* functions were changed to
return by value. For consistency, also pass gasmix by value.
Note that on common 64-bit platforms struct gasmix is the size
of a pointer [2 * 32 bit vs. 64 bit] and therefore uses the
same space on the stack. On 32-bit platforms, the stack use
is probably doubled, but in return a dereference is avoided.
Supporting arbitrary gas-mixes (H2, Ar, ...) will be such an
invasive change that going back to pointers is probably the
least of our worries.
This commit is a step in const-ifying input parameters (passing
by value is the ultimate way of signaling that the input parameter
will not be changed [unless there are references to said parameter]).

There were two functions for getting gas-mixes at a certain timestamp:
- get_gasmix() for repeated queries.
- get_gas_at_time() for a single query.
Since the latter is a special case of the former, simply call
the former in the latter. Moreover, rename to get_gasmix_at_time()
for consistency.
Replace on get_gasmix() call, which was outside of a loop by the
corresponding get_gasmix_at_time() call.

Currently, get_gasmix_from_event() and get_gasmix() return pointers
to either static or to (possibly changing) dive data. This seems like
a dangerous practice and the returned data should be used immediately.
Instead, return the gasmix by value. This is in preparation of
const-ifying input parameters of a number of core functions, which
will ultimately let the merge() function take const-arguments in
preparation of undo of dive-merging.
On common 64-bit systems gasmix (two "int"s) is the size of a pointer
and can be returned in a register.
On 32-bit systems a pointer to the struct to be filled out will be
passed.
Since get_gasmix() now returns a value, the first invocation is
tested by a NULL-initialized "struct event *". Document this in
a comment.

If the dive list is filtered the map should hide dive locations
that do not match the dive list filter.
To achieve that, loop over dives instead of dive sites in
MapWidgetHelper::reloadMapLocations() and discard
dives that are hidden by the filter. Then check if a dive
has a dive site attached to it and re-use the old functionality.

The filter code was an unholy intermixture of backend and frontend
logic, which made it hard to access it from outside of the UI.
Notably, it expected that Qt would call filterAcceptsRow on all rows.
For trip-view, apparently the filter functions were called twice
(once for filtering the trip, then for filtering the individual dives).
Make the filtering explicit, by calling showDive() for all dives in
MultiFilterSortModel::myInvalidate(), setting the hidden_by_filter
flags accordingly and ultimately invalidating the filter.
The UI code only accesses the hidden_by_filter flag set previously.
The "justCleared" flag can then be removed, since accessing the filter
does not have side effects. Moreover, there is no noticeable performance
gain by returning out early.

The compiler complained about assigning the "const char *" returned by
mb_cstring() to a "char *". The warning is correct, as the returned
buffer still belongs to the membuffer. The code only worked because
destruction of the membuffer was "forgotten".
Fix this by using the "detach_buffer()" function, which passes ownership
to the caller and accordingly returns a "char *".

To make dive-filtering accessible from other parts of the code,
break out the actual dive-filtering code into a function that

Conceptually, the doFilter() functions shouldn't modify the dive
they test. Therefore, make the argument const. To do this, constify
the parameter of get_dive_location(), which likewise seems to be
the right thing to do.

Change the signature from of the virtual doFilter() functions from
bool doFilter(struct dive *d, QModelIndex&, QAbstractItemModel*) const;
to
bool LocationFilterModel::doFilter(struct dive *d) const;
as the QModelIndex and QAbstractItemModel parameters were not used.
This makes this functions independent from Qt's model/view
framework. This is in preparation for making the undo-machinery
compatible with the filtering.
