Pulling %{client:} into rlm_perl

[Boris Lytochkin]

Hi.

I'm implementing support for hash-like access (r/o I guess) to %{client:...} from rlm_perl module. The issue is that CONF_SECTION structure is just typedef'ed and there is no access to 
pair/section_tree from outside main/conffile.c.

Should I pull `struct conf_part` into headers or make some sort of walker inside conffile.c?

p/s. There's declaration of seems-to-be handy function:
int dump_config(CONF_SECTION const *cs);
but no code is there anymore :)
