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.

#It is unclear if url_stat handlers should emit a warning in case
#PHP_STREAM_URL_STAT_QUIET is not specified and the resource does
#not exist. Most url_stat handlers never emit messages; the plain
#one does only so in the extraordinary event of an open_basedir
#restriction.
#But in case, php_stat uses PHP_STREAM_URL_STAT_QUIET for the
#FS_EXISTS, which suggests that mere checks on file existence are
#supposed to use this flag (arguably).
#The downside is that important diagnostic messages might be
#omitted.
