Encoded in every sample. The depth is in multiples of 10 feet which gives
somewhat odd metric stop depth - but rounding to full meters would take
care of that.

This is ignoring a ton of data that the dive computer provides. But it
gives profile, tank pressure and temperatures - so it's a start.
This patch adds a set_dtr and set_rts call to the serial interface prior
to interacting with the device. This change is required for the A300CS to
talk to the computer.

For the Tusa Zen, the header is 16 bytes smaller. With this change, the
gasmixes and the intial temperature are now parsed correctly.
The tank pressure samples have also been disabled manually, because this
is a non-air integrated model that doesn't seem to set the initial tank
pressure to the magic value 10000.
Commit d414da70a42afca0096e0402a426c4ac8d2a2881 added support for a
second Aeris Elite T3 variant. But the parser wasn't updated to take
into account this second model number.
For the Aeris Manta and Sherwood Insight, the header size should be 16
bytes smaller. Due to this mistake not only two samples were missing,
but also the byte offset for the gas mixes were wrong. This resulted in
invalid gas mixes, with oxygen percentages exceeding 100%.
The Hollis TX1 has several new features compared to the other models. It
supports trimix and up to 6 different gas mixes can be configured. It
also has twice the amount of memory, which requires an extra bit for the
ringbuffer pointers.
The new Oceanic OCi appears to be almost identical to the already
supported Oceanic OC1. The most important change is the different
location for the logbook ringbuffer.
The only difference with the two other Oceanic OC1 variants is the new
model number. I have absolutely no idea what's the purpose of such a
silly change.
Currently, each backend has it's own function to verify whether the
object vtable pointer is the expected one. All these functions can be
removed in favor of a single isintance function in the base class,
which takes the expected vtable pointer as a parameter.
Functions which are called through the vtable, don't need to verify the
vtable pointer, and those checks are removed.
The term "backend" can be confusing because it can refer to both the
virtual function table and the device/parser backends. The use of the
term "vtable" avoids this.
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.
