Requires FreeBSD's -lfetch...
Implementations to other URL APIs encouraged.
Probably should be moved to -llutil.

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)

NEXTID would not be set to one higher than the highest number
used, but to one higher than the last entry in the ldif file.
