We check that the given microsecond fraction is in the valid range
[0, 1000000[, and otherwise mark it as invalid. We also drop the
useless do loop; a plain block is sufficient here.
When getting the properties of a DatePeriod instance we have to retain
the proper classes, and when restoring a DatePeriod instance we have to
cater to DateTimeImmutable instances as well.

And convert some object to string conversion related recoverable
fatal errors into Error exceptions.
Improve exception safety of internal code performing string
conversions.
Arbitrary DateInterval objects don't have well-defined comparison
semantics. Throw a warning and treat the objects as uncomparable.
Support for comparing DateInterval objects returned by
DateTime::diff() may be added in the future.
Function strftime is part of the C89 standard [1] and current systems
don't need to check for its presence anymore.
Additionally, checks for strftime function in tests have been removed
since the PHP strftime function is now always available.

Changes:
- PHP_TM_GMTOFF removed
- HAVE_TM_GMTOFF replaced with HAVE_STRUCT_TM_TM_GMTOFF
- HAVE_TM_ZONE replaced with HAVE_STRUCT_TM_TM_ZONE
- HAVE_TZNAME removed
The PHP_TM_GMTOFF macro can be replaced with Autoconf's AC_CHECK_MEMBERS
that defines the HAVE_STRUCT_TM_TM_GMTOFF symbol instead of the
HAVE_TM_ZONE.
The HAVE_TZNAME symbol is not used in current code. The obsolete
HAVE_TM_ZONE symbol has been replaced with more proper
HAVE_STRUCT_TM_TM_ZONE. These are defined by the AC_STRUCT_TIMEZONE
macro.
get_properties() constructs these as fresh objects with no relation
to the internals, there is no need to clone them again. Additionally
the current implementation leaks memory, because the original objects
are never freed (see PR #3121).
This patch removes the so called local variables defined per
file basis for certain editors to properly show tab width, and
similar settings. These are mainly used by Vim and Emacs editors
yet with recent changes the once working definitions don't work
anymore in Vim without custom plugins or additional configuration.
Neither are these settings synced across the PHP code base.
A simpler and better approach is EditorConfig and fixing code
using some code style fixing tools in the future instead.
This patch also removes the so called modelines for Vim. Modelines
allow Vim editor specifically to set some editor configuration such as
syntax highlighting, indentation style and tab width to be set in the
first line or the last 5 lines per file basis. Since the php test
files have syntax highlighting already set in most editors properly and
EditorConfig takes care of the indentation settings, this patch removes
these as well for the Vim 6.0 and newer versions.
With the removal of local variables for certain editors such as
Emacs and Vim, the footer is also probably not needed anymore when
creating extensions using ext_skel.php script.
Additionally, Vim modelines for setting php syntax and some editor
settings has been removed from some *.phpt files. All these are
mostly not relevant for phpt files neither work properly in the
middle of the file.
