A shutdown or unmount of AFS on OpenBSD will invariably result in a kernel
panic. This is because the afs_unmount() routine does not (can not?) force
vnode releases if the vnode is still busy. However, it continues on
nonetheless and dies a horrible death a little later.
This update causes a return from afs_unmount() with EBUSY if all the vnodes
weren't released. This results in error messages on shutdown but the overall
process continues more reliably and reboots, for example, work.
There is likely a better solution to this but at least this is no worse than
a system crash and it doesn't require console (or power button) intervention
so it should do until I have the chance to explore further.

When determining the volume type of a volume, vsu_GetVolumeID() checks
to see if the volume name ends in '.backup' or '.readonly' by backing
up the appropriate number of characters from the end of the name. It
does not, however, check to see if it skips past the beginning of the
volume name. This can result in a segmentation fault (which it has for
me on many occasions during a vos release) depending on where memory
is allocated or how/if memory is protected.
This patch corrects this behaviour by checking the volume name string
length prior to doing the string comparison.

Pioctl input and output handling was being handled in an adhoc
manner, with little or no detection of input and output buffer
overflow. Whilst overflow is difficult to provoke on a real system,
due to the size of the buffers being allocated for output, the code
was difficult to read, and fragile to maintain.
This patch adds an XDR like abstraction for marshalling and
unmarshalling pioctl data. Whilst the real XDR can't be used and
maintain backwards compatibility, this gives a similar elegance.
Input and output pointers are replaced with instances of
struct afs_pdata, which store both a pointer to the current position
in the data stream, and a note of where the stream ends.
All access to a data stream is now performed through a set of helper
functions, which handle the reading and writing of integers, strings,
and arbitrary blocks of bytes. An 'inline' function is provided for
those cases where direct access to the stream is required.
