url-normalize

URI Normalization function:

• Take care of IDN domains.
• Always provide the URI scheme in lowercase characters.
• Always provide the host, if any, in lowercase characters.
• Only perform percent-encoding where it is essential.
• Always use uppercase A-through-F characters when percent-encoding.
• Prevent dot-segments appearing in non-relative URI paths.
• For schemes that define a default authority, use an empty authority if the default is desired.
• For schemes that define an empty path to be equivalent to a path of "/", use "/".
• For schemes that define a port, use an empty port if the default is desired
• All portions of the URI must be utf-8 encoded NFC from Unicode strings

Inspired by Sam Ruby's urlnorm.py
