Log Message:
Updated crypto++ to 5.5.2.

Changes since 5.2.1:
5.2.2 - added SHA-224
      - put SHA-256, SHA-384, SHA-512, RSASSA-PSS into DLL

5.2.3 - fixed issues with FIPS algorithm test vectors
      - put RSASSA-ISO into DLL

5.3 - ported to MSVC 2005 with support for x86-64
    - added defense against AES timing attacks, and more AES test vectors
    - changed StaticAlgorithmName() of Rijndael to "AES", CTR to \ 
"CTR"

5.4 - added Salsa20
    - updated Whirlpool to version 3.0
    - ported to GCC 4.1, Sun C++ 5.8, and Borland C++Builder 2006

5.5 - added VMAC and Sosemanuk (with x86-64 and SSE2 assembly)
    - improved speed of integer arithmetic, AES, SHA-512, Tiger, Salsa20,
      Whirlpool, and PANAMA cipher using assembly (x86-64, MMX, SSE2)
    - optimized Camellia and added defense against timing attacks
    - updated benchmarks code to show cycles per byte and to time key/IV setup
    - started using OpenMP for increased multi-core speed
    - enabled GCC optimization flags by default in GNUmakefile
    - added blinding and computational error checking for RW signing
    - changed RandomPool, X917RNG, GetNextIV, DSA/NR/ECDSA/ECNR to reduce
      the risk of reusing random numbers and IVs after virtual machine state
      rollback
    - changed default FIPS mode RNG from AutoSeededX917RNG<DES_EDE3> to
      AutoSeededX917RNG<AES>
    - fixed PANAMA cipher interface to accept 256-bit key and 256-bit IV
    - moved MD2, MD4, MD5, PanamaHash, ARC4, WAKE_CFB into the namespace \ 
"Weak"
    - removed HAVAL, MD5-MAC, XMAC

5.5.1 - fixed VMAC validation failure on 32-bit big-endian machines

5.5.2 - ported x64 assembly language code for AES, Salsa20, Sosemanuk, and Panama
        to MSVC 2005 (using MASM since MSVC doesn't support inline assembly on x64)
      - fixed Salsa20 initialization crash on non-SSE2 machines
      - fixed Whirlpool crash on Pentium 2 machines
      - fixed possible branch prediction analysis (BPA) vulnerability in
        MontgomeryReduce(), which may affect security of RSA, RW, LUC
      - fixed link error with MSVC 2003 when using "debug DLL" form of \ 
runtime library
      - fixed crash in SSE2_Add on P4 machines when compiled with
        MSVC 6.0 SP5 with Processor Pack
      - added support for newly released compilers: MSVC 2008, GCC 4.2, Sun CC 5.9,
        Intel C++ Compiler 10.0, and Borland C++Builder 2007
