[Bug runtime/10490] New: make big printfs possible

Some tracing scenarios require copying large buffers into the trace output.
Several parts of the runtime conspire currently to impose a smaller limit,
one that can't easily be overridden. We should fix this, so that scripts
such as this one work:
printf("%.*M", 65536, $some_buffer)
(64K representing a hypothetical jumbo network packet)
It may help if the "stap -s NNNN" value is used to derive a print
buffer size limit, or if there is a -DPARAMETER for it.
