KVM: Support mixed endian machines
Currently kvmtrace is not portable. This will prevent from copying a trace file from big-endian target to little-endian workstation for analysis. In the patch, kernel outputs metadata containing a magic number to trace log, and changes 64-bit words to be u64 instead of a pair of u32s.
