fcbaa9726c correct the syscall return type 
Long size syscall return values such as shmat()'s and lseek()'s are
broken, because lower 32 bits are only returned.

bdc945cb34 mcexec: wait for the signal to be received 
The mcexec may send a signal to itself in order that the mcexec
terminates abnormally.
Generally, the signal is delivered to the thread which sent the signal.
In this case, the signal terminates the mcexec immediately.

However, if the signal is delivered to another thread,
the thread which sent the signal can call exit(3)
before the signal terminates the mcexec.

069bb10a02 make mcexec ignore garbage request 
When a signal is forwarded from McKernel,
ioctl(MCEXEC_UP_WAIT_SYSCALL) may return EINTR error.
In this case, though no syscall request has been received,
the mcexec starts to process the syscall requst that is garbage.
