[stgt] [PATCH 09/14] tgt: BSD support - bind() is picky about names

[Boaz Harrosh]

The BSD's bind does not like the Linux IPC names with zero
as first char and zeros padding at end. #ifdef a different
implementation for BSD.

Note: On BSD, after exit a file is left in current directory
      with the pipe's name. The "up" script was modified to
      delete this file before and after the tgtd load.
      (File name is: TGT_IPC_ABSTRACT_NAMESPACE)
