Sync final and leading newlines

This patch adds some missing newlines, trims some multiple redundant
final newlines into a single one, and trims few redundant leading
newlines.

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 [2] and later standards [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."

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