Defer hostname determination to the post_config hook

[tomhughes]

This is an untested (compiled but not run) attempt to fix #41 by deferring the looking up of the hostname until the post_config hook.

It looks like it doesn't work.

scfg->configs->nelts appears to be 0 in the post_config hook and so the code is never executed.

[tomhughes]

Is that just the first time it is called or is that still true the second time?

[apmon]

Unfortunately it seems to be true for both.

[tomhughes]

Hmmm... Of course if there was actually any decent documentation for the apache module API then it might be easier to figure these things out...

[apmon]

There definitely seems to be a lack of documentation when exactly these hooks get called and how to fully use them

I think I might have tried a very similar thing in the past as well and it didn't work. Particularly I think it was getting the initial configuration Notice (you refer to in your other ticket) off the console and into the logs.

This doesn't seem to work for me. However, Tom has verified that it does work for him on both apache 2.2 and apache 2.4. Can anyone else verify if it works for them or not? Or might have an idea what is different? My guess is that it might have something to do about where things are defined. I.e. in the virtual server config or the general server, but I couldn't so far make it work to support this guess.
