CSS parser: Add error recovery while parsing @-webkit-keyframes key values.
<http://webkit.org/b/115175>

Source/WebCore:

From Blink r148714 by <apavlov@chromium.org>:

If not a percentage, "from", or "to" value is used in a key list, the rule is erroneous,
and due to the absense of recovery, the parser skips the following, valid CSS rule.

On a related note, keyframes, whose selectors contain invalid keys, should be discarded
altogether, according to <http://www.w3.org/TR/css3-animations/#keyframes>

Unreviewed build fix: Fix the name of DyldInterpose.h in
SecItemShimLibrary.mm, fix the name of WebProcessShim.dyld in
WebContentServiceEntryPoint.mm, and stop linking against libWTF.a
directly (which means removing ASSERTs from
CookieStorageShimLibrary.cpp).
