[Tim Kientzle]

Author: kientzle

New Revision: 189424
URL: http://svn.freebsd.org/changeset/base/189424

Log:
  Merge r390,r391,r392,r397 from libarchive.googlecode.com:  Virtualize
  "close" and "finish" across both read and write interfaces.
  (Someday, "finish" should be renamed to "free" to better reflect
  what it actually does...)
