Detect the number of available cores and limit the thread allocation accordingly. On decoder side limit the number of threads to the max number of token partition. Core detetction works on Windows and Posix platforms, which define _SC_NPROCESSORS_ONLN or _SC_NPROC_ONLN. Change-Id: I76cbe37c18d3b8035e508b7a1795577674efc078

Object files are built at the place where configure is launched.

of that shown above. If the option --disable-foo is listed, then

the default value for foo is enabled.
