Cosmetic: Multiple cosmetic changes

- Added missing space to 'if', 'for', 'while' and 'switch' when it's followed by '('
- Added missing space after a comma and remove space before comma (with some exceptions)
- Remove trailing spaces
- Convert tab to spaces

Note: Only affects files with extension "cpp" and "h" under /src/server
