Don Cross 82be64ab2a C: lunar eclipse obscuration
Starting to add support for calculating the intensity
of lunar eclipses and solar eclipses in terms of "obscuration".

This commit adds calculation of obscuration for lunar eclipses
in C/C++. The structure returned by SearchLunarEclipse and
NextLunarEclipse now includes an `obscuration` field whose value
is in the range [0, 1], indicating what fraction of the Moon's
apparent disc is covered by the Earth's umbra at the eclipse's peak.
