bsd-user: Add system independent stack, data and text limiting

Eliminate the x86 specific stack stuff in favor of more generic control
over the process size:
    target_maxtsiz  max text size
    target_dfldsiz  initial data size limit
    target_maxdsiz  max data size
    target_dflssiz  initial stack size limit
    target_maxssiz  max stack size
    target_sgrowsiz amount to grow stack
These can be set on a per-arch basis, and the stack size can be set
on the command line. Adjust the stack size parameters at startup.
