Multiple system-wide ldap.conf files

[Hallvard B Furuseth <h.b.furuseth@usit.uio.no>]

I'd like to add support for multiple system-wide ldap.conf files.
Our site needs one which comes with the LDAP package, and one which
the host admin can create to override.

One way would be to add this to include/ldap_defaults.h:
    /* Array initializer for system-wide LDAP configuration files.
     * The contents of late files override earlier ones.
     * Update the FILES section of doc/man/man5/ldap.conf.5 to match.
     */
    #define LDAP_CONF_FILELIST { LDAP_CONF_FILE }
after the line
    #define LDAP_CONF_FILE LDAP_SYSCONFDIR LDAP_DIRSEP "ldap.conf"

Another way: An ldap.conf directive "tryinclude <filename>" so the
package's ldap.conf can include the host-specific ldap.conf.  Also
allows a user's ldap.conf to include some package's ldap.conf, if
needed.  And it allows include-loops, so there should be a "max include
depth" limit.

Opinions?
