This patch adds missing newlines, trims multiple redundant final
newlines into a single one, and trims redundant leading newlines in all
*.phpt sections.
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.

The data for messages of type SOL_SOCKET/SCM_RIGHTS was not being
passed correctly. There were actually two bugs: (1) the number of file
descriptors being passed was being read incorrectly (the length of the
cmsg array was being read instead of that of its 'data' element), as a
result it was generally being reported as always three elements
('level', 'type' and 'data') and (2) the allocated block for writing
the file descriptors was being acessed incorrectly because a 1-based
counter was being used as if it was 0-based.
Any of these two bugs would probably be enough to cause heap
corruption.
