Jens Axboe ff9da691c0 pipe: change /proc/sys/fs/pipe-max-pages to byte sized interface ...

This changes the interface to be based on bytes instead. The API
matches that of F_SETPIPE_SZ in that it rounds up the passed in
size so that the resulting page array is a power-of-2 in size.

The proc file is renamed to /proc/sys/fs/pipe-max-size to
reflect this change.
