The memory managements for DeviceDetails was very sketchy.
First of all, sharing a pointer to a structure between threads
seems like a recipe for disaster. Secondly, the structure was
a QObject and when first generated included in the (silly)
Qt object tree, but when generated in the threads it was not.
Clearly, this leaks.
Instead, use value semantics and use local copies of the
structure. I didn't go full length and use std::move to
move the data, because this doesn't work through signals
(which are the wrong abstraction here, but OK) and secondly
I didn't have time to analyze whether the caller still
needs the data after passing it down to the worker thread.
To be able to pass an object through signals, the class
has to be registered in the Qt MetaType system. Super
ugly, but fine for now. Ultimately, this whole thing should
probably be replaced by futures, co-routines, or whatever.
Moreover, this removes the prefix from number of "m_*"
function parameters. By convention, "m_" marks member
variables, which function parameters are not.

make DeviceDetails a metatype
So that we can pass it as value through the signal/slot system.

Unfortunately Coverity doesn't understand that most Qt data
structures are copy-on-write. It's a mis-feature of Qt, but
it is the way it is. Thus, passing by value is not an issue.
Out of ca. 25 warnings only two were legit. Let's silence
the others by either std::move()ing or passing by reference,
as would be idiomatic C++, which Qt is not.

Requires changes in libdivecomputer.

This version is compile-time checked and therefore less risky with
respect to refactoring.
Since the same three signals were connect()ed for three different
threads-objects, do this in a new function.

Replaces some enums with names that do not clash with windows #defines.
Specifically:
ERROR -> ERRORED, PASCAL->PASCALS, IGNORE->IGNORED,FLOAT->FLOATVAL

Having subsurface-core as a directory name really messes with
autocomplete and is obviously redundant. Simmilarly, qt-mobile caused an
autocomplete conflict and also was inconsistent with the desktop-widget
name for the directory containing the "other" UI.
And while cleaning up the resulting change in the path name for include
files, I decided to clean up those even more to make them consistent
overall.
This could have been handled in more commits, but since this requires a
make clean before the build, it seemed more sensible to do it all in one.
