Retire conf_api.h and the API therein

This makes the _CONF_* layer of the conf module internal and gets rid
of the entirely unused conf_api.h.

Make CONF_METHOD opaque

Much of conf is designed in such a way that you really have to reach into
its structs. This one piece can be hidden. It might even be removed soon.

lhash_local.h was previously needed since conf/conf_api.c and

lhash.c and remove the header.

Make LHASH_OF() and STACK_OF() use opaque structs

This removes internals of these two special snowflakes and will allow
further simplifications. Unfortunately, there are some pieces of
software that actually use LHASH_OF() (looking at you, pound, Ruby, and
openssl(1)), so we get to keep exposing this garbage, at least for now.

Expose lh_error() as a symbol to replace a macro reaching into _LHASH.
lh_down_load() is no longer available. _LHASH and _STACK are now opaque,
LHASH_NODE becomes internal-only.

Remove all getenv() calls, especially those wrapped by issetugid().
getenv()'s wrapped by issetugid() are safe, but issetugid() is correct
difficult to impliment on many operating systems. By accident, a grand
experiment was run over the last year, where issetugid() returned 1 (the
safe value) on a few operating systems. Noone noticed & complained that
certain environment variables were not working.......
