just have it return the slot number or -E... - the caller checks
the sign anyway

no point, really - we couldn't keep those across the calls of
getdents(); it would be too easy to DoS, having all slots exhausted.

We only need it while the service operation is actually in progress
since it is only used to co-ordinate the client-core's memory use. The
kernel allocates its own space.
Also clean up some comments which mislead the reader into thinking
the readdir buffers are shared memory.

This only changes the names of things, so there is no functional change.

OrangeFS was formerly known as PVFS2 and retains the name in many places.
I leave the device /dev/pvfs2-req since this affects userspace.
I leave the filesystem type pvfs2 since this affects userspace. Further
the OrangeFS sysint library reads fstab for an entry of type pvfs2
independently of kernel mounts.
I leave extended attribute keys user.pvfs2 and system.pvfs2 as the
sysint library understands these.
I leave references to userspace binaries still named pvfs2.
I leave the filenames.

The latter is never used, the former has one user and would be
better off spelled out right there.

Al Viro glanced at readdir and surmised that getdents
would misbehave the way it was written... and sure enough.

Don't check for negative rc from boolean.
Don't pointlessly initialize variables, it short-circuits
gcc's uninitialized variable warnings. And max_new_nr_segs
can never be zero, so don't check for it.
Preserve original kstrdup pointer for freeing later.
Don't check for negative value in unsigned variable.
