        Add SHA-1 for new WebSocket protocol
        https://bugs.webkit.org/show_bug.cgi?id=55039

        The code is based on Chromium's portable SHA-1 implementation
        (src/base/sha1_portable.cc). Modifications were made in order
        to make the code comply with WebKit coding style.

        (WTF::testSHA1): This function will be run the first time SHA1
        constructor is called. This function computes a few hash values
        and checks the results in debug builds. However, constructor is
        probably not a good place to run these tests, so we need to find
        a good place for it (bug 55853).
