Import mbuffer-20140310 into pkgsrc, packaged by Brian Bennett.

mbuffer is a tool for buffering data streams with a large set of
unique features:

 * direct support for TCP based network targets (IPv4 and IPv6)
 * ability to send to multiple targets in parallel (distribution mode)
 * support for multiple volumes
 * I/O rate limitation
 * high/low watermark based restart criteria
 * configurable buffer size
 * on the fly MD5 hash calculation
 * highly efficient, multi-threaded implementation

It is especially useful, if you are writing backups to fast tape drives
or libraries.


(jperkin)

The mbuffer tool is used to buffer data streams and show the I/O rate
and summary to the user.  It is especially useful for writing backups to
fast tape drives or streaming them over the network.  If used correctly,
it can prevent buffer underruns and speed up the whole backup or
transfer process.
