Make it possible to have samples without depth from libdivecomputer

Browse source 
Normally, all samples have depths associated with them, and most dive
computers likely don't even have the concept of a sample without a depth.

However, the new Suunto EON Steel definitely has samples with just time
updates (and perhaps other data, like events) and no depth at all.  We
get unhappy about that, and interpret it as having a zero depth.  Which
doesn't look very nice.

This just makes all samples default to the same depth as the previous
sample.  For normal samples with a depth value, that will just override
that default.
