Xin LI 82aebf697c Add two new fcntls to enable/disable read-ahead: ...

- F_READAHEAD: specify the amount for sequential access.  The amount is
   specified in bytes and is rounded up to nearest block size.
 - F_RDAHEAD: Darwin compatible version that use 128KB as the sequential
   access size.

A third argument of zero disables the read-ahead behavior.

Please note that the read-ahead amount is also constrainted by sysctl
variable, vfs.read_max, which may need to be raised in order to better
utilize this feature.

Thanks Igor Sysoev for proposing the feature and submitting the original
version, and kib@ for his valuable comments.
