<h3>Log Message</h3>
<pre>URLParser should parse IPv4 addresses as the last two pieces of an IPv6 address
https://bugs.webkit.org/show_bug.cgi?id=162991

Reviewed by Saam Barati.

Source/WebCore:

The last 32 bits of an IPv6 address can be written in the form of an IPv4 address,
but the syntax is stricter than if it were just an IPv4 address.  There must be 4 pieces,
and each piece must be decimal (no octal or hex allowed).  These should serialize to
regular hex IPv6 addresses.

Covered by new API tests.

* platform/URLParser.cpp:
(WebCore::URLParser::parseIPv4Piece):
(WebCore::URLParser::parseIPv4Host):
(WebCore::URLParser::parseIPv4PieceInsideIPv6):
(WebCore::URLParser::parseIPv4AddressInsideIPv6):
(WebCore::URLParser::parseIPv6Host):
(WebCore::URLParser::parseIPv4Number): Deleted.
* platform/URLParser.h:
