The memory leak occurs when more than one UserComment tag is present in
the EXIF data. It's still considered corrupt EXIF data, but this ensures
the memory is freed before trying to set to already allocated memory.
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.

We must not close the stream in exif_read_from_impl(), since it is the
responsibility of the (caller's) caller to do so, if it actually opened
the stream.
We simplify the reproduce script, which is actually about supplying a
path to a directory (opposed to a regular file), and use `.` instead of
`/` to also make it work on Windows.
This patch removes the exif version in the phpinfo output to sync it
with the rest of the php bundled extensions. Also in the past the
revision id from the version control system was used and is today not
needed anymore.
The MakerNote is not necessarily null-terminated, so we must not use
`strlen()` to avoid OOB reads. Instead `php_strnlen()` is the proper
way to handle this.
