Steve Reinhardt 99bf6ed084 Syscall DPRINTF and warning cleanup.
base/trace.hh:
    Need std:: on DPRINTFR reference to string class.
base/traceflags.py:
    Remove SyscallWarnings trace flag... we should always print warnings
    so nothing undesirable goes unnoticed.  Replaced with (currently unused)
    Syscall flag.
sim/syscall_emul.cc:
    Change SyscallWarning DPRINTFs into warn() calls.
    Uncomment SyscallVerbose DPRINTFs.
sim/syscall_emul.hh:
    Change SyscallWarning DPRINTFs into warn() calls.
    Call fatal() instead of ad-hoc termination.
