CCAPI client rpc fixes

CCAPI client rpc fixes

On Windows XP, cci_os_ipc_thread_init() causes additional threads to be
spawned immediately, which results in a vicious cycle until Windows
resources are exhausted.  Instead, defer thread_init() until it is really
needed.

Also, use the MSDN-recommended defaults for RPC calls instead of random
constants.
