PROJ/src/transformations, branch 6.3.1

Modify verbosity level of some debug/trace messages

2019-12-25T09:45:20+00:00

- unitconvert, ell_set and helmert were using debug level, which is
  too verbose. Using trace instead
- proj_trans() was using trace to indicate the operation it selects.
  Changing it to debug

Remove unneeded C99 compatibility functions from math.cpp and proj_math.h
I'll do the clean up of the -std=c89 flags etc. as a separate pull request.

Delete proj_math.h. Replace includes by ; we'll see if anyone

Merge pull request #1322 from rouault/ossfuzz_fixes

Various ossfuzz fixes

Use 1st eccentricity instead of 2nd eccentricity

2019-03-16T09:21:26+00:00

By mistake the second eccentricity was used in a few places in the
Molodensky transform. According to the literature the first eccentricity
should always be used in the eccentricity.

This only affects the output slightly. Reported test coordinates
differed by less than a millimeter.

Fixes #1321
