        src/sys/sys: param.h proc.h systm.h

Log Message:
add dtrace syscall glue:
- adds 2 members to sysent: these are the entry and exit probe ids
  they are non-zero only when dtrace is loaded
- add an emul specific probe for dtrace: this is NULL unless the emulation
  supports dtrace and is loaded
- adjust the syscall stub call trace_enter/exit if needed for systrace
- add more info to trace_enter and exit needed by systrace
