There was a pattern of code like
match_action(line, state, dive_action, ARRAY_SIZE(dive_action));
The doubling of the array might cause copy & paste errors, where
only one array is replaced.
Therefore, determine the length of the array with (hopefully
easily understood) template tricksery.

When iterating over the converted strings of a line, the
first entry of the array would be popped off, leading to
a full copy of the remaining array.
Instead, use an index in the parser state.

The converted strings were stored in a membuffer and later
converted to std::strings. Generate an std::string directly
to avoid unnecessary copying.
Ultimately, when the core structures are converted to
std::string, there should be no copying of the string data
at all (unless formatting is applied or small string
optimization kicks in, of course).

Make the memory management easier to follow. I feel that the old
code was leaking left and right, but not sure because it was so
intractable.

Simplifies memory management. Think about unglobalizing this,
once everything is in C++ so that we can put an std::string
into struct divelog.
