This patch is the implementation patch for the server of usercrash.
Usercrash works in C/S model: usercrash_s works as usercrash server,
which is to handle events from client in endless loop. Once server
receives dump request from client, it will create usercrash_0x file
under /var/log/usercrashes/ and send file fd to client.
