Remove local variables

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.

Use zval_ptr_dtor() instead of zval_dtor() in internal functions that destroy new created object (This is safer and produces less code)

Replace legacy zval_dtor() by zval_ptr_dtor_nogc() or even more specialized destructors.
zval_dtor() doesn't make a lot of sense in PHP-7.* and it's used incorrectly in some places.

Removed or simplified incorrect SEPARATE_*() macros usage.

Cleanup (avoid string reallocations)

Use ZSTR_ API to access zend_string elements (this is just renaming without semantick changes).

Fix Intl constructor leaks

Drop the Z_OBJ(return_value) = NULL hack and return status code
from ctor function instead.

Fix leak in transliterator_transliterate()

Patch improvement:

Removed the corresponding core code.
Fixed ext/com_dotnet and ext/date.
Refactored ext/intl changes.
Improved ext/fileinfo and ext/pdo changes.
Fixed tests.

Converted intl extension to use IntlException in constructors.
