Fix #75102: `PharData` says invalid checksum for valid tar

Apparently, there are broken tarballs out there which are actually in
ustar format, but did not write the `ustar` marker. Since popular tar
tools like GNU tar and 7zip have no issues dealing with such tarballs,
Phar should also be more resilient.

Thus, when the first checksum check of a tarball in (presumed) in old-
style format fails, we check whether the checksum would be suitable for
ustar format; if so, we treat the tarball as being in ustar format.

Closes GH-6479.

Fix #79503: Memory leak on duplicate metadata

Duplicate metadata can only happen if someone tampers with the phar, so
we can and should treat that as error.

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.
