I forgot to update the device and parser initialization functions to
store the context pointer into the objects. As a result, the internal
context pointers were always NULL.
The public api is changed to require a context object for all
operations. Because other library objects store the context pointer
internally, only the constructor functions need an explicit context
object as a parameter.
Adding the "dc_" namespace prefix (which is of course an abbreviation
for libdivecomputer) should avoid conflicts with other libraries. For
the time being, only the high-level device and parser layers are
changed.
The public header files are moved to a new subdirectory, to separate
the definition of the public interface from the actual implementation.
Using an identical directory layout as the final installation has the
advantage that the example code can be build outside the project tree
without any modifications to the #include statements.
The Suunto Vyper, Spyder and Eon store a surface event after the last
depth sample. Adding an artificial zero depth sample avoids the problem
of having an incomplete sample without a depth measurement.
Because these devices also store the tank pressure and/or the
temperature at the begin/end of the dive, these measurements are
associated with the new surface samples.
