Log Message:
- add kqueue option (off by default - perhaps it should be on by
  default at the next version bump?)
- set SSL_{CFLAGS,LIBS} when calling configure script so they are
  found correctly on Solaris, and make the configure script do what it
  claims and ignore pkg-config when these are set.
- add lib-sql Makefile patch from Dovecot CVS so this builds correctly
  when no SQL auth support is built.
