Add #include <linux/cred.h> dependencies to all .c files rely on sched.h
doing that for them.

Note that even if the count where we need to add extra headers seems high,
it's still a net win, because <linux/sched.h> is included in over
2,200 files ...

Implement mandatory export_operations, so it is possible to export befs via
nfs.

Removing all trailing whitespaces in befs.

I was skeptic about tainting the history with this, but whitespace changes
can be ignored by using 'git blame -w' and 'git log -w'.

No idea why some comments have signatures. These predate git. Removing them
since they add noise and no information.
