    * WebCore.xcodeproj/project.pbxproj: Added new files.
    
    * bindings/js/JSCryptoAlgorithmDictionary.cpp:
    (WebCore::createAesKeyGenParams): Added bindings for AesKeyGenParams.
    (WebCore::JSCryptoAlgorithmDictionary::createParametersForGenerateKey): Handle
    algorithms that generate AES and HMAC keys.
    
    * bindings/js/JSSubtleCryptoCustom.cpp: (WebCore::JSSubtleCrypto::generateKey): Added.
    
    * crypto/CryptoAlgorithmAesKeyGenParams.h: Added.
    
    * crypto/CryptoKey.cpp: (WebCore::CryptoKey::randomData):
    * crypto/CryptoKey.h:
    * crypto/CryptoKeyMac.cpp: Added
    Expose a function that produces random data for symmetric crypto keys. Cross-platform
    implementation uses ARC4 code from WTF, while Mac uses a system function that
    provides a FIPS validated random number generator.
    
    * crypto/CryptoKeyAES.cpp: (WebCore::CryptoKeyAES::generate):
    * crypto/CryptoKeyAES.h:
    Added a function that creates AES keys.
    
    * crypto/SubtleCrypto.idl: Added generateKey.
    
    * crypto/algorithms/CryptoAlgorithmAES_CBC.cpp:
    (WebCore::CryptoAlgorithmAES_CBC::generateKey): Added.
    
    * crypto/algorithms/CryptoAlgorithmHMAC.cpp:
    (WebCore::CryptoAlgorithmHMAC::generateKey): Added.
    
    * crypto/keys/CryptoKeyHMAC.cpp: (WebCore::CryptoKeyHMAC::generate):
    * crypto/keys/CryptoKeyHMAC.h:
    Added a function that creates HMAC keys.
    
    * crypto/mac/CryptoAlgorithmAES_CBCMac.cpp: Removed generateKey stub, the implementation
    ended up in cross-platform file.
    
    * crypto/mac/CryptoAlgorithmHMACMac.cpp: Ditto.

    * crypto/subtle/hmac-generate-key.html: Added.
    
    * crypto/subtle/sha-1-expected.txt: Now that crypto.webkitSubtle.generateKey exists,
    a different exception is raised.
