parse-xml.c:
Instead of always allocating a buffer when parsing a node, only
do so for "strings" in the utf8_string() function. Also move the
whitespace trimming of node contents in there.
This change also requires that most parsing functions don't
free the passed buffer, as it will be part of memory allocated
by libxml2.
visit_one_node(), now also has a xmlIsBlankNode() check, where if
1 is returned, the node contains only whitespace or is empty and should
not be processed.

This should really be done in libdivecomputer, but that can't happen until
the API there gets extended to support tank sizes. So for now with this
code we manually parse the raw dive data (if downloaded via
libdivecomputer from a Cobalt) and setup the tank size ourselves.
This had relatively limited testing so far.

Those only come from a number of development versions of Subsurface that
didn't include the deviceid in the divecomputer entry. There is no way of
telling different dive computers (of the same model) apart, so assigning a
nickname to such an entry then creates incorrect output when loading an
XML file from someone else (e.g. Linus and I both have a Uemis SDA and
both may have entries for our own SDA with deviceid 0; then the nickname
Subsurface shows for any Uemis SDA entry with a deviceid of 0 depends on
whether I last loaded his XML file or mine; that makes no sense).
This should only affect the develoers who stored XML files with one of the
development version of Subsurface that didn't store deviceids.

There was one code path where we didn't strdup the nickname - and this got
triggered when parsing XML files with divecomputerid entries for dive
computers that were already in the config. The nickname is then replaced
with the nickname from the parser - and that memory is later reused...
We should cleanup that nickname, anyway, and that also takes care of
making sure we have our own copy.

This patch makes a couple of modifications:
1) divelist.c:delete_single_dive() now tries to free all memory associated
with a dive, such as the string values for divemaster, location, notes &
etc.
2) dive.c:merge_text(), now always makes a copy in memory for the returned
string - either combined or one of the two which are passed
to the function.
The reason for the above two changes is that when (say) importing the same
data over and over, technically a merge will occur for the contained dives,
but mapped pointers can go out of scope.
main.c:report_dives() calls try_to_merge() and if succeeds the two dives
that were merged are deleted from the table. when we delete a dive,
we now make sure all string data is cleared with it, but also in the actual merge
itself, which precedes, copies of the merged texts are made (with merge_text()),
so that the new, resulted dive has his own text allocations.

Interesting crash. Importing a file gets us to a stage where we have a

bogus. And in import_files() we assume that all is still fine and try to

actual crash from happening by making sure the pointer is non-NULL before

Having it there with the model information seemed to make sense but on
second thought it's the wrong spot to keep that information, especially
since we were storing it in the XML file in every single dive.

This adds the capability to actually view all your dive computers, by
adding a menu item under "Log"->"View"->"Next DC" to show the next dive
computer.
Realistically, if you actually commonly use this, you'd use the
accelerator shortcut. Which right now is Ctrl-C ("C for Computer"),
which is probably a horrible choice.
I really would want to have nice "next/prev dive" accelerators too,
because the cursor keys don't work very well with the gtk focus issues.
Being able to switch between dives would also make the "just the dive
profile, maam" view (ctrl-2) much more useful.
The prev/next dive in the profile view should probably be done with a
keyboard action callback, which also avoids some of the limitations of
accelerators (ie you can make any key do the action). Some gtk person,
please?
Anyway, this commit only does the dive computer choice thing, and only
using the accelerators.

We had logic to remove duplicate dive computer information after merging
dives, but it didn't actually work.
Why? Because we had used the 'res' dive computer pointer to traverse the
list of dive computers, so it no longer actually pointed to the first
dive computer in the result list any more, and so the "remove redundant"
code only removed redundant dive computers from a limited and incomplete
list.

The idea behind editing timestamps had of course been the typical "oops, I
forgot to set my time correctly" which shifts a dive (or a few of them) by
a few hours but keeps the overall order of dives the same).
But reasonable people might argue that they can envision a scenario where
more dramatic changes are being made. And we need to deal with the impact
this has on dive trips.
Here we handle a couple of simple cases:
- this is the only dive in a trip; just update the trip
(this can still cause problems if the new time is in the middle of an
existing trip).
- this dives moves before the start of the trip it is in; let's remove it
from that trip (this response is a bit simplistic - but as I tried to
say, I don't expect this to be a common use case; and removing it at
least doesn't lead to entirely unexpected behavior).
- this dive moves past the end of this trip into the range of a different
trip (in this case we remove the dive from the current trip and allow it
to interrupt the trip it is moving into).

Early in the libdivecomputer 0.3 development cycle Jef and I implemented
deco and ndl as events. That wasn't a wise design choice and we agreed to
switch this to be instead new sample types which makes much more sense
(and is much more aligned with the way we are handling them inside
Subsurface). So this commit tracks the change in libdivecomputer. Since
this happened during the development cycle there isn't a way to detect
this at compile time - so you need to make sure you have a matching
version of libdivecomputer when compiling Subsurface.
To make this easier: this commit of Subsurface requires a libdivecomputer
version that includes the libdivecomputer commit d5d44c1e0ffd "Convert

This splits the dive time, depth, pressure and temperature maxima and
minima setup from the per-dive-computer "create_plot_info()" function
into one setup function that walks _all_ the dive computers, so that we
have a global maxima and minima.
That way the graph scaling we set up will now fit the data from all dive
computers rather than just the particular one we are plotting. So if
you switch back-and-forth between computers, the scale (which is defined
