From: Bin Meng <bin.meng@windriver.com>

At present the codes uses sigaction() to install signal handler with
a flag SA_RESETHAND. Such usage can be covered by the signal() API
that is a simplified interface to the general sigaction() facility.

Update to use signal() to install the signal handler, as it is
available on Windows which we are going to support.
