Modified Files:
	src/sys/miscfs/procfs: procfs_cmdline.c
Log Message:
Some changes to `cmdline' to make it work properly:
- Don't error out on P_SYSTEM or SZOMB processes; instead, do what ps(1)
would do, i.e. the p_comm in parenthesis.
- Use uvm_io() (or procfs_rwmem() if !UVM) to read the target process's
psstrings and argument vector.  Using copyin() is problematic, because
it operates on the current processes!  That is, the old code would
always get the `cmdline' of the process reading the file, not that of
the target process.
