to avoid unportable casts of integers to pointers and back.

rewrote sockbuf_buf_init macro not to expand its argument multiple times.

lber: ifdef'ed out lber_..set_nonblock() function because it used ioctl's.
  If it remains, it needs to be written to support various methods for
  setting non-blocking.  ioctls should probably be last choice.  configure
  could detect existance of fcntl(), ioctl(), etc.
bdb2:
  added .dsp/.dsw files and did some basic cleanup (still needs work).

2. Make ldbm_Env a failure-safe entity.

v3 MODDN (MODRDN) operation on the client side.

from what the current code can handle.

Use pthread_*attr_default.
Don't use a void return value from pthread_yield.

which only part of a LDAPMessage is available on a socket.

The server-code seemed to handle this correctly already, so I didn't touch

My apologies for the hack in ber_get_next :-).

support for TLS and SASL will be build.

Please inform me of any problems.

  AVL_CMP, AVL_DUP, AVL_FREE, AVL_APPLY.
Apply casts as needed.
Change data pointer from caddr_t to void *.

Also add initial slapd .dsw/.dsp files.  Still needs work (mainly syslog).
