Docs: remove "Concepts:" and related comments in /*T .. T*/ blocks

Remove all \*T ... comment blocks with e.g.

cd src && find . -type f -exec sed -i '/^[! ] *\/\*T$/,/^[! ]*T\*\/$/d' {} \;

Clean up resulting double blank lines with e.g.

cd src && find . type f \( -name "*.c" -o -name "*.cxx" -o -name "*.F" -o -name "*.F90" \) -exec sh -c "cat -s {} > tmp && mv tmp {}" \;

Manually revert those changes from the vendored code (src/sys/yaml)

Manually restore a few comments from these blocks.

Manually remove "Concepts:" and "Processors:" comments from files
which have these outside of "\*T" blocks automatically deleted above.

gcc/gfortran-10: fix errors/warnings

The primary issue now is - gfortran defaults to flagging argument mismatch as error.
We can work-around this with '-fallow-argument-mismatch' option - however this switches from errors to warnings.

And the only way to disable this warning is '-w' i.e disable all warnings.

Fixes involve adding interface definitions for all prototypes that get used. [and work-around mpich by using a(1) for scalars]
