Minor changes ported from MSOpentechRedis. Note that this does not rev up the version to 2.8.9 but will take closer. Here is a list:
     fix for issue #39 pipe mode doesn't recognise stdin input:
     fox for issue 84. now recognizing "stdout" as as stdout.
     Added support for SIO_LOOPBACK_FAST_PATH (http:/msdn.microsoft.com/en-us/library/windows/desktop/jj841212%28v=vs.85%29.aspx) . This speeds up localhost performance on Win8/Server2012+ significantly. In order to take advantage of this clients will have to enable socket fast loopback before connect().
fdapi not properly mapping fstat in config.c, so we ended up invoking CRT version without the rfd->fd translation resulting in the CRT calling exit()
Merge branch '2.8.9_msopen' into 2.8.4_msopen
