Indicate when a sentence is not parsed or is not valid. Before this
change, it was not clear from the example run whether each sentence is
parsed properly or not.
Instead of comparing floats "x == y", perform comparison
"fabs(x - y) <= epsilon", where epsilon is acceptable error that
accumulates in computation of x and/or y.
Because in this case all integers are small and all floats are exactly
representable under IEEE754, epsilon may be zero in our tests.

This is an API breaker that incorporates the following big changes:
1. The (value, scale) float, as used in minmea, is a compound type. It
should be declared and used as such.
2. Some platforms, notably avr-gcc, have 16-bit ints. Make life easier
for them by using int_least32_t for floating point values.
3. As a side effect, the following functions were renamed:
* minmea_coord -> minmea_tocoord
* minmea_float -> minmea_tofloat
Migration guide for user code (easy unless you do fancy stuff):
1. Replace calls to minmea_{coord,float}.
2. Replace int32_t with int_least32_t in user code if your platform
requires this.
