URI string into its component
parts. An "undef" value is returned for those parts that are not
present. The $path part is always present (but can be the empty
string) and is thus never returned as "undef".
No sensible value is returned if this function is called in a scalar
context.
URI string from its parts.
Missing parts are signaled by passing "undef" for the corresponding
argument.
Minimal escaping is applied to parts that contain reserved chars
that would confuse a parser. For instance, any occurrence of '?' or '#'
in $path is always escaped, as it would otherwise be parsed back
as a query or fragment.
