  Added files:
    tools/regression/sockets/pr_atomic Makefile pr_atomic.c 
  Log:
  Drop all received data mbufs from a socket's queue if the MT_SONAME
  mbuf is dropped, to preserve the invariant in the PR_ADDR case.
  
  Add a regression test to detect this condition, but do not hook it
  up to the build for now.
