I've always wanted to make the CONF library more adaptable. Here's

the result.

I have retained the old behavior of the CONF_* functions, and have
added a more "object oriented" interface through NCONF_* functions
(New CONF, you see :-)), working the same way as, for example, the
BIO interface.  Really, the CONF_* are rewritten so they use the
NCONF_* functions internally.

In addition to that, I've split the old conf.c code into two files,
conf_def.c and conf_api.c.  conf_def.c contains the default config
object that reads a configuration file the standard OpenSSL way, as
well as configuration file with Win32 registry file syntax (I'm not
sure I got that one right).  conf_api.c provides an API to build other
configuration file readers around (can you see a configuraion file in
XML?  I can :-)).

Finally, I've changed the name conf_lcl.h to conf_def.h, since it's
made specifically for that "class" and none others.
