The current --sysroot parsing attempts to keep from leaking memory by
treating the empty string specially (sine this is the initial value),
but it ends up leaking memory when the arg is an empty string. So if
someone uses --sysroot "", the old value is leaked, as is the new one.

back.

It's useful to be able to trace just the system calls the simulated
program is calling, so add a new --trace-syscall option for ports to
leverage if they choose.

Pull the model data (register addresses/sizes) out of the different model
files and into the machs.h header. The models themselves don't care about
where they're mapped, only the mach code does. This allows us to keep the
model headers from being included in the mach code which can cause issues
with model-specific names colliding. Such as when a newer device model is
created, but with incompatible register names/layouts.
