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.

Given that ICU is a set of lively developed libraries, that ICU 50.1
has been released on 2012-11-05, and PHP 7.4 is scheduled to be
released seven years after it, we consider it appropriate to ditch
these legacy versions.
Particularly, that would be a reasonable groundwork to implement part
two of the “Deprecate and remove INTL_IDNA_VARIANT_2003” RFC[1], namely
to default idn_to_ascii()'s and idn_to_utf8()'s $variant parameter to
INTL_IDNA_VARIANT_UTS46, which is not defined in ICU < 4.6.

To better support IntlCalendar, added this function:
string IntlDateFormatter::formatObject(IntlCalendar|DateTime $obj [,
array|int|string $format = null [, string $locale = null).
$format is either of the constants IntlDateFormatter::FULL, etc., in
which case this format applies to both the date and the time, an array
in the form array($dateFormat, $timeFormat), or a string with the
SimpleDateFormat pattern.
This uses both the Calendar type and the timezone of the passed object
to configure the formatter (a GregorianCalendar is forced for
DateTime).
Some stuff was moved around and slighlt modified to allow for more code
reuse.
