Fix several deficiencies, as compared to ptrace(2):
...
* Did not check for P_SUGID on ATTACH.
* Did not check for tracing of init on ATTACH.
* Did not turn off single-step mode on RUN or DETACH.
* Might have screwed up reparenting in some cases.
* Allowed anyone to detach the process.

Change the second and third args to struct vfsops' (*vfs_mount)() to
...
'const char *', and 'void *', respectively. The second arg is taken directly
from user arguments, and is const there, so must be const in the prototypes
and functions. The third arg is also taken directly from user arguments.
It doesn't have to be changed, but since it's cleaner to keep the type
the same as the user arg's type, and I'm already making the 'const char *'
change...
