Michael Meffie 9c0db059b6 vol: convert vnode macros to inline functions 
Convert the vnode macros to inline functions to fix integer overflows
for very large vnode numbers (and generally improve the code robustness
and readability).

The macro version of vnodeIndexOffset() will evaluate to an incorrect
offset for very large vnode numbers due to 32-bit integer overflow. The
vnode index file will then be corrupted when writing to the incorrect
offset.

In code paths where the vnode number incorrectly defined as a signed
32-bit integer, this change prevents vnodeIndexOffset() from evaluating
to a negative result when a vnode number is larger than 2^31.

Thanks to Mark Vitale for reporting and providing analysis.

README 

AFS is a distributed file system that enables users to share and
access all of the files stored in a network of computers as easily as
they access the files stored on their local machines. The file system is
called distributed for this exact reason: files can reside on many
different machines, but are available to users on every machine.

OpenAFS 1.0 was originally released by IBM under the terms of the
IBM Public License 1.0 (IPL10).  For details on IPL10 see the LICENSE

the relevant copyright holders.  The LICENSE file in this directory
contains more details, thought it is not a comprehensive statement.
