Summary: Documentation about name of a session should be less
restrictive

I believe this is due to legacy reasons. In past, PHP had register globals settings, which means
cookie names must meet PHP variable naming restrictions. This option no longer exists, so I think
this restriction should be elevated.

From manual page: http://www.php.net/function.session-name

Documentation mentions that only alphanum chars should be used as a session name since the name can
be used in URLs and cookies.
This is a bit too restrictive and prevent for example to use the cookie prefixes restriction [1]
browser feature.
According to RFC1738 and RFC3986 the characters $-_.+!*'(), should also be safe to use in URLs
and it seems that RFC6265 does not add more limitations for cookies. These characters can probably
be added to the documentation as "safe to use" as the name of a session.
