Re-enable IO_NOCACHE, and use is in vnd.

Ensure that io to a file backing a vnd is IO_SYNC, so IO to a
vnd device is both synchronous and not cached in the buffer cache.

This allows the "mount" regress to work repeatably, and avoids
a situation where when the buffer cache cleaner runs to clear
dirty buffers while people are waiting, it actually increases the
dirty buffers when the writes to the underlying vnd are also
delayed.

In ext2fs_write(), clear the buffer on uiomove() failure unless it
was cleared on alloc just like we do in ffs_write().

Pass correct size to uvm_vnp_setsize() for large files.

Add kqueue support for ext2fs based on ffs. OK deraadt@

Move mnt_maxsymlink from struct mount to struct ufsmount.

The concept of differentiating between "short" and "long" symlinks is
specific to ufs/, so it shouldn't creep into the generic fs layer.
Inspired by a similar commit to NetBSD.

While there replace all references to mnt_maxsymlinklen in ufs/ext2fs
with EXT2_MAXSYMLINKLEN, which is the constant max short symlink len for
ext2fs. This allows to get rid of some (mnt_maxsymlinklen == 0) checks
there, which is always false for ext2fs.

Convert to uiomove. From Martin Natano.

Kill the "doclusterread" and "doclusterwrite" defines.

They are defined to 0 since the import of ext2fs 19 years ago.

Remove some includes include-what-you-use claims don't
have any direct symbols used. Tested for indirect use by compiling
amd64/i386/sparc64 kernels.

First step towards making uiomove() take a size_t size argument:
- rename uiomove() to uiomovei() and update all its users.
- introduce uiomove(), which is similar to uiomovei() but with a size_t.

ufs_setattr() was assuming that the flag bits that indicate
atime/mtime/ctime need to be updated weren't already set. When
they are, the code will end up treating the VNOVAL value from the
VFS layer as a time_t. Port the fix from FreeBSD: the critical bit
is to process the existing flag values before possibly setting them
again in ufs_setattr(). This diff pulls in a larger change from
FreeBSD to replace the macro ITIMES() with a function ufs_itimes()
and to remove the atime and mtime arguments from ffs_update(): only
ufs_setattr() used them so it makes more sense to just do the those
bits directly there.

final removal of daddr64_t. daddr_t has been 64 bit for a long enough
test period; i think 3 years ago the last bugs fell out.
ok otto beck others

If the current offset is strictly less than the process filesize
rlimit, then a write that would take it over the limit should be
clamped, making it a partial write.
