The -k, --insecure option is added to skip this verification. The
system wide trusted CA certificates will be loaded at startup. The
--cacert option is added to specify the trusted CA certificate file.
In client mode, now SPDY connection to the backend server is
established per thread. The frontend connections which belong to the
same thread share the SPDY connection.
With --client-mode option, shrpx now accepts unencrypted HTTP
connections and communicates with backend server in SPDY. In short,
this is the "reversed" operation mode against normal mode. This may
be useful for testing purpose because it can sit between HTTP client
and shrpx "normal" mode.
We should only call daemon() after ListenHandler is
instantiated, where SSL_CTX_use_PrivateKey_file is called,
otherwise we have no stdin/stdout to get the password for
keyfile.
To distinguish the to-be-installed programs and non-installable
example source code, the former programs, spdycat, spdydyd and shrpx,
were moved to src directory. spdynative was removed from Makefile
because it does not appeal to any users much.
