Additional language is needed for the LDAP_OPT_API_INFO option in the
ldap_get_option(3) man page.

A sentence needs to be added stating that the ldapai_info_version field must be
initialized in the LDAPAPIInfo struct before using it to call
ldap_get_option(NULL,LDAP_OPT_API_INFO,&info).

Current
------------------------------
LDAP_OPT_API_INFO
    Fills-in a LDAPAPIInfo; outvalue must be a LDAPAPIInfo *, point-
    ing to an already allocated struct. This is a read-only option.

Suggested
------------------------------
LDAP_OPT_API_INFO
    Fills-in a LDAPAPIInfo; outvalue must be a LDAPAPIInfo *, point-
    ing to an already allocated struct. The ldapai_info_version field
    must be initialized before making the call. This is a read-only
    option.
