We will want to set this option (but perhaps not
--enable-all-experimental-features) for F17 to be able to build the sudo
library.

At the time being the option is also turned on when
--enable-all-experimental-features is specified.
The second patch does the refactoring mentioned in #1145 - just moves
code around so that there are no #ifdefs in the main part of LDAP code.
