Sync final newlines in source code (#2017)

* Sync final newlines in source code

This patch syncs final newlines in source code files:
- trims multiple final newlines into one
- adds one final newline where it was missing

According to POSIX, a line is a sequence of zero or more non-' <newline>'
characters plus a terminating '<newline>' character. [1] Files should
normally have at least one final newline character.

C89 standard [2] and above [3] mention a final newline:
"A source file that is not empty shall end in a new-line character,
which shall not be immediately preceded by a backslash character."

Newline characters:
- LF (\n) (*nix and Mac, default)
- CRLF (\r\n) (Windows)
- CR (\r) (old Mac, obsolete)

Although it is not mandatory for all files to have this issue fixed, a
more consistent and homogeneous approach brings less of commit
differences issues and a better development experience in certain text
editors and IDEs.
