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

Now that zend_ulong is 64bit on 64bit platforms, it should be
sufficient to always use it, rather than supporting multiple
types.
API changes:
* _zend_print_unsigned_to_buf and _zend_print_signed_to_buf
no longer exist.
* smart_str(ing)_print_long and smart_str(ing)_print_unsigned
no longer exist.
* Instead of all these, zend_print_ulong_to_buf and
zend_print_long_to_buf should be used.
* smart_str_append_generic_ex no longer exists.
* smart_str(ing)_append_off_t(_ex) no longer exists, use
smart_str(ing)_append_long(_ex) instead.
