[vlc-devel] [PATCH] Revert "url: Remove duplicated path separators" (fixes #25374)

[remi at remlab.net]

From: Rémi Denis-Courmont <remi at remlab.net>

This was just plain wrong. Multiple forward slashes does not generally
have the same meaning as a single one. This notably broke some FTP and
DLNA servers.

This reverts commit 043988a2519f557856f14578b790da66283645fc.
