A number of standard posix types are used in exported headers, which
is not allowed if __STRICT_KERNEL_NAMES is defined. Change them all
to use the safe __kernel variant so that we can make __STRICT_KERNEL_NAMES
the default.

This is what I found, please review.


Indeed a lot of these look like real bugs, e.g. the use of off_t (which may be 32 bits in userspace while __kernel_off_t is 64 bits.)

So these are, indeed, critical bug fixes and should go into 2.6.29.

Some of these changes may require changes in userspace code if userspace has hacked around the problems. Those changes, though, really should happen, too.
