Fix #61700: FILTER_FLAG_IPV6/FILTER_FLAG_NO_PRIV|RES_RANGE failing

It makes no sense to compare IPv6 address ranges as strings; there are
too many different representation possibilities. Instead, we change
`_php_filter_validate_ipv6()` so that it can calculate the IP address
as integer array. We do not rely on `inet_pton()` which may not be
available everywhere, at least IPv6 support may not, but rather parse
the IP address manually. Finally, we compare the integers.

Note that this patch does not fix what we consider as reserved and
private, respectively, but merely tries to keep what we had so far.

Fix #81122: SSRF bypass in FILTER_VALIDATE_URL

We need to ensure that the password detected by parse_url() is actually

Alternative fix for bug 77423

That bug report originally was about `parse_url()` misbehaving, but the
security aspect was actually only regarding `FILTER_VALIDATE_URL`.
Since the changes to `parse_url_ex()` apparently affect userland code
which is relying on the sloppy URL parsing[1], this alternative
restores the old parsing behavior, but ensures that the userinfo is
checked for correctness for `FILTER_VALIDATE_URL`.

Added range options to the float validation filter

php_filter_int (called via the constant FILTER_VALIDATE_INT) has the options min_range
and max_range. they allow the user to not only test if a value is a double but also if
the value is inside a specific range. php_filter_float (called via the constant
FILTER_VALIDATE_FLOAT) didn't provide this yet, making validation of numeric but
not-only-int values more complicated for the user.
this commits implements the options min_range and max_range for the function
php_filter_float to fix this inconsistency.

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.
