Remove various bits of printing to stdout or stderr from the
nseries code, replacing it with a qemu log message where there's
an appropriate log category, and just dropping the output for
some of the more debug-like printing.

In particular, this will get rid of the 'mipid_reset' message
you currently get from 'make check'.

None of the printing I deleted seemed important enough to be worth
trying to retain as a trace event. I'm open to argument if anybody
genuinely uses it, though.

Was too deep down my TODO list.

Thanks,
