Revert "rtsp-session-pool: Make sure session IDs are properly URI-escaped"

This reverts commit 935e8f852d050b4939f1d0f44b38e9b55a2fbe36.

RFC 2326 states that session IDs may consist of alphanumeric as well as
the safe characters $-_.+ -- N.B. the percent character is not allowed.

Previously the session ID was URI-escaped, this meant that any character
which was not alphanumeric or any of the characters +-._~ would be
percent encoded. While the RFC (surprisingly) mentions that linear white
space in session IDs should be URI-escaped, it does not say anything
about other characters. Moreover no white space is allowed in the
session ID. Finally the percent character which is the result of
URI-escaping is not allowed in a session ID.

So there is no reason to do any URI-escaping, and now it is removed.
