from Paul Turgyan of University of Michigan.

Should resolve ITS#2664.

Currently discovered via a "feature", but should use a control.
Start of a control made, but needs to be better integrated (with
auto use in ldapmodify(1)).

Fix invalid structural object class chains in test schema

references, extended results, and extended partial results.  LDIF
extended to support these new features and reported version 2.
-L now limits output to LDIFv1 for compatibility reasons.  No
-L is now LDIFv2.  Old alternative form is no longer supported.

Use LDAP_TMPDIR (in ldap_config.h) instead of hardcoded /tmp
Use LDAP_FILE_URI_PREFIX (in ldap_config.h) instead of hardcoded
	file://tmp/

ldapsearch:
    use draft guidelines for determining when to use
    -t only writes binary attributes to files
    -tt writes all attributes to files
    output now lists URL instead of path to such files
    -T dir can be used to specify directory to create temp files in
    -V urlprefix can be used to change the URL prefix
    LDIF is now commented (can be disabled using -LL)
    LDIF now contains version attribute (can be disabled with -LLL)
LDIF:
    put interface changed to allow caller to specify how to encode
    put interface uses draft guidelines for determine when to base64 encode
    wrapping kludged to match old off by one bug
Tests:
    removed trailing space from some attributes (to avoid base64 encoding)
    enabled -LLL in defines.sh (should sed output to remove
        wrapping/comments/redundant separators)
Misc:
    updated codes outputting LDIF to use new put interface
TODO:
    handling of version attribute on input
    handling of URLs on input (ie: fetch URL)

a non-user-mod attribute (such as timeStamps).
Move generation of add_modify_attrs to frontend.
update of add_modify_attrs on modrdn needs work (currently
not updated to maintain consistency with replicas).

	adds POSIX RegEx (and removes BSD re_comp/re_exec) support.
* POSIX RegEx is not currently included in the distribution, however
	we will probably add Henry Spencer's REGEX library soon.
* ACL Group functionality is also included in this merge!
