Peter Maydell af7969605e linux-user: Provide new force_sig_fault() function 
In many places in the linux-user code we need to queue a signal for
the guest using the QEMU_SI_FAULT si_type.  This requires that the
caller sets up and passes us a target_siginfo, including setting the
appropriate part of the _sifields union for the si_type. In a number
of places the code forgets to set the _sifields union field.

Provide a new force_sig_fault() function, which does the same thing
as the Linux kernel function of that name -- it takes the signal
number, the si_code value and the address to use in
_sifields._sigfault, and assembles the target_siginfo itself.  This
makes the callsites simpler and means it's harder to forget to pass
in an address value.

We follow force_sig() and the kernel's force_sig_fault() in not
requiring the caller to pass in the CPU pointer but always acting
on the CPU of the current thread.
