GPMFMetersGenerator v1.03

This v1.03 version is the last stable version compatible with non-GLibC systems.

Further versions handle timestamp in GPX file as well as within GPMF stream using the GPSU tag : to parse and synchronize timestamps, they are relaying on functions which are not part of POSIX and a GLibC extension.

Workarounds are obviously possible but I choose the laziest solution as GPMFMetersGenerator is mostly a geek solution and I don't see large user audience w/o GLibC. Obviously, contributions are welcome.
