Bruce Evans 029b0fc88f Fix tracing of syscalls. The previous fix required the undocumented
option DDB_NO_LCALLS to stop ddb getting control and broke all ddb
tracing.  Now there is no option and no way for ddb to trace at
address _Xsyscall or to _Xsyscall, but tracing everywhere else
works.  The previous fix did unnecessary things for Linux syscalls.

Don't bother checking that syscall frames are for user mode.

Make debugger traps inside the kernel (except at addresses _Xsyscall
and _Xsyscall+1) fatal if ddb is not configured.  They "can't happen".

Add prototypes.

Remove stupid comments, e.g., /*ARGSUSED*/ for args that are used.
