Prefix names of system call implementation functions with `sys_'.

Add KTR_EMUL to indicate a switch between syscall emulations.
...
Currently this record is emitted only on exec. Maybe it should
be emitted on ktrace() attach too.

Not perfect, but there's no perfect solution to the "multiple interesting

Use sigcode fields in package structure. This seems to be the cleanest
...
way to deal with seperate trampoline code for emulation of other OSs,
it avoids having to clutter up kern_exec.c any further.
