Only in ERR/WARN/INFO/DBUG/OGS_FATAL and similar, not in

1. Changed urls to https which fixed the following error:

xsd/OpenGeoSysGLI.xsd, at line 1, column 66: Document is not a XML schema.
Error XSDError in ..., at line 3, column 194: Loaded schema file is invalid.

If this error ever pops up again try to cut the internet connection! No joke!

2. Local schema files are now copied to bin-directory during CMake configuration and package generatiion (install step).

Clang format run on near-the-header lines.

Happy New Year

This potentially saves a second copy compared to using const

Move parts from FileIO to GeoLib/IO and BaseLib/IO.
