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.

Remove AC_HEADER_DIRENT

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

This macro checks which header defines the `DIR` type. If `<dirent.h>`
is available it defines the `HAVE_DIRENT_H` symbol. Since the `<dirent.h>`
header is already checked in the `configure.ac`, this check is not needed
anymore. This macro also additionally checks for SCO Xenix (discontinued,
latest release 1989) dir and x libraries. [2]

Commit 6ed790685f9ddae11834f36b0ba4fea58afc805a introduced also
`<sys/dir.h>`. This header exists from times of UNIX System V and
provided definition of DIR type on these systems such as 4.3BSD.
Today `<sys/dir.h>` is kept for backwards compatibility and includes
the `<dirent.h>` on current systems. With `dirent.h>` present this
include is no longer required.

Remove unused Git attributes ident

The $Id$ keywords were used in Subversion where they can be substituted
with filename, last revision number change, last changed date, and last
user who changed it.

In Git this functionality is different and can be done with Git attribute
ident. These need to be defined manually for each file in the
.gitattributes file and are afterwards replaced with 40-character
hexadecimal blob object name which is based only on the particular file
contents.

This patch simplifies handling of $Id$ keywords by removing them since
they are not used anymore.

Path handling related refactorings

Primarily related to the path handling datatypes, to avoid unnecessary
casts, where possible. Also some rework to avoid code dup. Probably
more places are to go, even not path related, primarily to have less
casts and unsigned integers where possible. That way, we've not only
less warnings and casts, but are also safer with regard to the
integer overflows. OFC it's not a panacea, but still significantly
reduces the vulnerability potential.
