New Revision: 203774
URL: http://svn.freebsd.org/changeset/base/203774

Log:
  Use more standard way for setting nonblocking flag for a filedescriptor.
  This makes libusb porting a bit easier.
  
  There shouldn't by any negative change in behaviour after this commit.
  
  Remove redundant headers.
