execlog is a plugin that logs executed instructions with some useful

The output of the plugin is designed to be usable with other tools. For
example it could be used with a side-channel leakage model to create
side-channel traces from QEMU for security evaluation.

Changes since v1:
  - The output is now easier to parse.
  - Use QEMU logging API rather than FILE* to write output.
  - Don't reject memory information in user mode.
  - Merge memory information with instruction execution. Now one line
    means one instruction.
  - Add documentation.

Where you planning on posting v3? I'm just seeing if we can get this
merged before code freeze in a weeks time.

Thanks,

I had a deadline next week but I managed to move it later, so I can try to make the important changes tomorrow and send v3. I think I will contribute the support for triggering the beginning and end of tracing in another patch as I believe that's something we don't want to rush.
