Improve summary output.

Try at having a deterministic ouput of it, which still apparently is not
always the case when using SBCL, now that it's been switched to using
the explicit *terminal-io* rather than t.

This change is needed for CCL support, though, where you don't get to
write to the same stream from different threads.
Fix with-monitor support of :start-logger option.

It used to still launch an extra set of threads for monitoring where,
and that would confuse CCL where it's not possible to write into a
stream from more than one thread concurrently.
Allows to build pgloader image using CCL.

Too many Makefile commands where hard-coded using SBCL, which prevented
from building successfully against CCL. That's now fixed.
No patches needed anymore to compile pgloader.
Include the new version of the manpage, pre-compiled.
