Apply code style to the complete source code

[tcsabina]

It would be really necessary to apply a coding style guide to the complete source code. There are so many styles applied, a contributor like myself find it utmost difficult to apply the correct one.

There are plenty of tools out there that good to this. We just need to define the style guide, and apply to tool. A before/after build is necessary, so we could bit-compare the build output after the formatter was applied. To make sure that the changes are cosmetic.

If someone could identify the code style that must be followed, I would be happy to execute this task.
