Update to 0.9.17:

Releasing 0.9.17. -CG

Fixing return value of MHD_get_timeout if timeouts are not in use.
        (#1914). -rboulton

Trying to fix accidental addition of a "Connection: close" footer
under certain (rare) circumstances. -CG

Small updates to the tutorial.
Releasing 0.9.16. -CG

shutdown(RDWR) fails on OS X after shutdown(RD), so only use
shutdown(WR) if we already closed the socket for reading (otherwise
OS X might not do shutdown (WR) at all). -CG

Force adding of 'Connection: close' to the header if we (for whatever
reason) are shutting down the socket for reading (see also
#1760). -CG

Treat EAGAIN the same way as EINTR (helps on W32). -LRN

Made sockets blocking again for non-Linux platforms as non-blocking
sockets cause problems (#1824) on Cygwin but offer better performance
on Linux (see change on August 11 2011). -CG/pross

Fixed problems with testcases on W32. -LRN

Fixed MHD_CONNECTION_OPTION_TIMEOUT for HTTPS (#1811). -CG
