Add a check to prevent a computation from underflowing and causing
...
a panic due to an attaempt to allocate a buffer for a terabyte or
so of data when an attempt is made to create sparse data (e.g.
a holey file) more than 1 block past the end of the file.
Note: some other areas of this code need to be looked at,
since they might cause problems when the file size exceeds 2GB,
due to storing results in ints when the computations are being
done with quad sized variables.

Major fixes for procfs..
...
Implement a "variable" directory structure. Files that do not make
sense for the given process do not "appear" and cannot be opened.
For example, "system" processes do not have "file", "regs" or "fpregs",
because they do not have a user area.
"attempt" to fill in the user area of a given process when it is being
accessed via /proc/pid/mem (the user struct is just after
VM_MAXUSER_ADDRESS in the process address space.)
Dont do IO to the U area while it's swapped, hold it in place if possible.
Lock off access to the "ctl" file if it's done a setuid like the other
pseudo-files in there.

Major fixes for ptrace()...
...
PT_ATTACH/PT_DETACH implemented now and fully operational.
PT_{GET|SET}{REGS|FPREFS} implemented now, using code shared with procfs
PT_{READ|WRITE}_{I|D} now uses code shared with procfs
ptrace opcodes now fully permission checked, including ownerships.
doing an operation to the u-area on a swapped process should no longer
panic.
running gdb as root works for me now, where it didn't before.
general cleanup..
Note, that this has some tightening of permissions/access checks etc.
Some of these may be going too far.. In particular, the "owner" of the
traced process is enforced. The process that created or attached to
the traced process is now the only one that can "do" things to it.

Change ar's internal error routine to call err() instead of errx()

so that when ar has a problem (like trying to update a read-only
