Commit 867c27c23a5c enabled the n_directio_opens code
in open/close, which sets/clears NNONCACHE, for
IO_APPEND. This code should not be enabled unless
newnfs_directio_enable is non-zero.
This patch reverts that part of commit 867c27c23a5c.
A future patch that fixes the case where the
file that is being written IO_APPEND is mmap()'d.

Function vm_reserv_test_contig has incorrectly used its alignment

mistakenly when it was unable to provide a satisfactory set of pages.

When we load an ELF file (kernel or module) we do seek(2) a lot to
parse/load the different sections of the ELF file.
Protocol like TFTP suffers a lot from this as there is no resume or
a way to start the tranfer from a specified offset in the file.
fs_preload is added to help those protocol.
Call preload just after opening the ELF file that we need to load so
the underlying method can cache the hole file and then read/lseek operations
are faster.

When we load a kernel or module we open/close it a few times.
Since we're using the same port number each time and that we requested
the same file the ACK that we send are valid on the server side and the
server send us the file multiple times.
This makes tftp loading time very inconsistant due to the UDP "flood" that
we have to process.

The cookies argument is only used by the NFS server. NFSv2 defines the
cookie as 32 bits on the wire, but NFSv3 increased it to 64 bits. Our
VOP_READDIR, however, has always defined it as u_long, which is 32 bits
on some architectures. Change it to 64 bits on all architectures. This
doesn't matter for any in-tree file systems, but it matters for some
FUSE file systems that use 64-bit directory cookies.

In NFSv2, the directory cookie was 32-bits. NFSv3 widened it to
64-bits and SVN r22521 widened the corresponding argument in
VOP_READDIR, but FreeBSD's NFS server continued to treat the cookies as
32-bits, and 0-extended to fill the field on the wire. Nobody ever
noticed, because every in-tree file system generates cookies that fit
comfortably within 32-bits.
Also, have better type safety for txdr_hyper. Turn it into an inline
function that type-checks its arguments. Prevents warnings about
shift-count-overflow.

[Passes] Fix relative lookup table converter pass
This patch fixes the relative table converter pass for the lookup table
accesses that are resulted in an instruction sequence, where gep is not
immediately followed by a load, such as gep being hoisted outside the loop
or another instruction is inserted in between them. The fix inserts the
call to load.relative.instrinsic in the original place of load instead of gep.
