coda: remove CODA_FS_OLD_API

Browse source 
While fixing CONFIG_ leakages to the userspace kernel headers I ran into
CODA_FS_OLD_API.

After five years, are there still people using the old API left?
Especially considering that you have to choose at compile time which API
to support in the kernel (and distributions tend to offer the new API for
some time).

Jan: "The old API can definitely go.  Around the time the new
      interface went in there were some non-Coda userspace file system
      implementations that took a while longer to convert to the new API,
      but by now they all switched to the new interface or in some cases
      to a FUSE-based solution."

To compile the coda client support as a module, choose M here: the
module will be called coda.

bool "Use 96-bit Coda file identifiers"

help
A new kernel-userspace API had to be introduced for Coda v6.0
to support larger 128-bit file identifiers as needed by the
new realms implementation.
However this new API is not backward compatible with older
clients. If you really need to run the old Coda userspace
cache manager then say Y.
For most cases you probably want to say N.
