FaceUri does not recognize IPv4-mapped IPv6 address

Description
FaceURI: wsclient://[::ffff:76.90.11.239]:56366
Expected: no error, wsclient://76.90.11.239:56366 is constructed
Actual: Malformed URI: wsclient://[::ffff:76.90.11.239]:56366
FaceUri should treat an IPv6 endpoint containing IPv4-mapped IPv6 address as the corresponding IPv4 endpoint (eg. When scheme is not specified, "tcp4" should be chosen instead of "tcp6")
Problem was discovered when using WebSocket faces.
1400690340.435746 FATAL: [NFD] Malformed URI: wsclient://[::ffff:76.90.11.239]:56366
This happens when NFD is running dual-stack WebSocket while the client is from IPv4. A temporary fix is to disable IPv6 for WebSocket faces.

WebSocket++ using IPv4-mapped IPv6 addresses implies that IPv4 connectivity is not available on FreeBSD because IPv4-mapped IPv6 is disabled by default.

A closer look reveals that the bug is in FaceUri parsing routine.
This routine has no control over the scheme name.
