Revert "lavf/utils: Allow url credentials to contain a slash."

This reverts commit dd06f022b07438d650c82255dff16908ba04244a.

Fixes ticket #7871 and reopens ticket #7816.

The introduced regression caused URL's with @ in them to be parsed incorrectly
which is a bigger issue then not being able to specify the slash character as a
password.

I think there are better ways to fix the original issue, like being able to
specify HTTP username and password as a protocol option, or adding a protocol
option to percent-decode the URL first.
