Style: Changing for loops and ints according to the Coding Style Guide

Hi,

With respect to https://openfoam.org/dev/coding-style-guide/ , assuming ESI-OpenFOAM applies the same, the two points might need to be corrected throughout the code:

-- for (int i=0; i<10; i++) ++ for (label i = 0; i < 10; i++)

-- int iter = 0; ++ label iter = 0;

Some examples of the style inconsistencies can be found in src/.../wallFunctions, e.g.:

https://develop.openfoam.com/Development/OpenFOAM-plus/blob/master/src/TurbulenceModels/turbulenceModels/derivedFvPatchFields/wallFunctions/fWallFunctions/fWallFunction/fWallFunctionFvPatchScalarField.C#L72

Additional typos from OpenFOAM.org issue tracker:

https://www.openfoam.com/documentation/cpp-guide/html/classFoam_1_1functionObjects_1_1forceCoeffs.html#details

-- type Type name: forces ++ type Type name: forceCoeffs

https://develop.openfoam.com/Development/OpenFOAM-plus/blob/master/tutorials/incompressible/pimpleDyMFoam/wingMotion/wingMotion2D_simpleFoam/0.orig/omega#L13

-- epsilon ++ omega
