Experimental valgrind tests

Experimenting with valgrind - I don't intend to check this in as-is (for one,
I'd need to make the OpenSSL suppressions work for everyone) but take a look?

https://codereview.appspot.com/6811056/diff/1/src/suppressions
File src/suppressions (right):

https://codereview.appspot.com/6811056/diff/1/src/suppressions#newcode2
src/suppressions:2: <openssl-rand0>
These two are by design (OpenSSL without -DPURIFY gathering randomness).

src/suppressions:18: fun:_ZN4util24WriteTemporaryBinaryFileERKSsS1_
Line 124 in util.cc:

    ssize_t bytes_written = write(fd,
                                  reinterpret_cast<const char*>(data.data()),
                                  data.length()); // line 124

The data in question is a serialized protobuf.

src/suppressions:24: fun:_ZN4util9HexStringERKSs
Line 41 in util.cc:
string HexString(const string &data) {
  string ret;
  for (unsigned int i = 0; i < data.size(); ++i) {
    ret.push_back(nibble[(data[i] >> 4) & 0xf]);  // line 41
    ret.push_back(nibble[data[i] & 0xf]);
  }
  return ret;
}

Ditto, data is a serialized protobuf.
