Ok. I spent quite a lot of time trying to get fetchmail and kerberos to
properly build in Debian, and in the process I've cleaned up a lot of the
cruft in the configure.in side of things. I don't know how well the work I
did will mix with Nalin's, though.

Here is the patch. This addresses the follwing issues:

* Build correctly under Heimdal kerberos if it is compiled with db2 and
  OpenSSL support (Debian's is)
* Build the kerberos.c stuff (KPOP) only for kerberosIV, to avoid breakage.
  I don't know if this is 100% correct, but now at least IMAP and POP3
  behave the same way regarding kerberosV.
* Build without any fuss for both kerberosIV and V at the same time.
* Move all the kerberos header mess to kerberos.h, and #include that
  in driver.c and kerberos.c.

Tested using the Heimdal Kerberos V libs, Kungliga Tekniska Högskolan (the
Royal Institute of Technology in Stockholm, Sweden)'s kerberos IV libs, and
the MIT reference implementation of KerberosV (all as packaged in Debian).

I tried not to break the build in any of the platforms, but it would be
advisable to test it.
