MINOR: cfgparse: finish to set up servers outside of the proxy setup loop

Till now servers were only initialized as part of the proxy setup loop,
which doesn't cover peers, tcp log, dns, lua etc. Let's move this part
out of this loop and instead iterate over all registered servers. This
way we're certain to visit them all.

The patch looks big but it's just a move of a large block with the
corresponding reindent (as can be checked with diff -b). It relies
on the two previous ones ("MINOR: server: add a global list of all
known servers and" and "CLEANUP: lua: set a dummy file name and line
number on the dummy servers").
