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.

In cases where messages are delivered in non ASCII compatible encoding,

Remove AC_FUNC_UTIME_NULL

Autoconf 2.59d (released in 2006) [1] started promoting several macros
as not relevant for newer systems, including the AC_FUNC_UTIME_NULL.

This macro checks if `utime(file, NULL)` sets file's timestamp to the
current time and defines the `HAVE_UTIME_NULL` symbol. This check was
relevant on very old systems (for example, 4.3BSD released in 1986) and
today can be omitted for systems with utime since it should be well
supported by now. [2]
