ba7a55d934 Add two options to allow mount to avoid covering up existing mount points.
The two options are

* nocover/cover:  Prevent/allow mounting over an existing root mountpoint.
E.g., "mount -t ufs -o nocover /dev/sd1a /usr/local" will fail if /usr/local
is already a mountpoint.
* emptydir/noemptydir:  Prevent/allow mounting on a non-empty directory.
E.g., "mount -t ufs -o emptydir /dev/sd1a /usr" will fail.

Neither of these options is intended to be a default, for historical and
compatibility reasons.

daba4da81d Add a new "untrusted" option to the mount command. Its purpose
is to notify the kernel that the file system is untrusted and it
should use more extensive checks on the file-system's metadata
before using it. This option is intended to be used when mounting
file systems from untrusted media such as USB memory sticks or other
externally-provided media.

It will initially be used by the UFS/FFS file system, but should
likely be expanded to be used by other file systems that may appear
on external media like msdosfs, exfat, and ext2fs.

31260bf042 vfs_donmount: in certain cases try r/o mount if r/w mount fails
If the operation is not an update, if neither r/w nor r/o mode is
explicitly requested, if the error code hints at the possibility of the
media being read-only, and if the fallback is allowed, then we can try
to automatically downgrade to the readonly mode.

This is especially useful for auto-mounting of removable media that
sometimes can happen to be write-protected.

The fallback to r/o is not enabled by default.  It can be requested on a
per-mount basis with a new mount option, 'autoro'.  Or it can be
globally allowed by setting vfs.default_autoro.

2e564269d0 Disconnect non-MPSAFE SMBFS from the build in preparation for dropping
GIANT from VFS. In addition, disconnect also netsmb, which is a base
requirement for SMBFS.

In the while SMBFS regular users can use FUSE interface and smbnetfs
port to work with their SMBFS partitions.

Also, there are ongoing efforts by vendor to support in-kernel smbfs,
so there are good chances that it will get relinked once properly locked.

in-kernel implementations around, found in other operating systems,
don't really seem clean and solid enough to be imported at all.
If someone wants to reconsider in-kernel NTFS implementation for

up is expected.

In the possibility of a future maintenance of the code and later

c783576970 Add a -o mountprog parameter to mount which explicitly allows
an alternative program to be used for mounting a file system.
Ideally, all file systems
should be converted to pass string arguments to nmount(), so that
/sbin/mount can handle them.  However, certain file systems such as FUSE have
not done this, and want to have their own userland mount programs.

For example, to mount an NTFS file system with the FUSE NTFS driver:

mount -t ntfs -o mountprog=/usr/local/bin/ntfs-3g /dev/acd0 /mnt

or via an fstab entry:

/dev/acd0  /mnt  ntfs    ro,noauto,mountprog=/usr/local/bin/ntfs-3g       0       0

4b4f91707c Teach mount(8) about a 'late' keyword, which means the file system should
not be mounted unless the -l flag was specified.

Add an rc script, mountlate, which basically runs 'mount -a -l'.  It runs
after DAEMON but before LOGIN.

This is useful for things like loopback mounts, because mountcritremote
runs before mountd  / nfsd (since /usr might be a remote file system), so
an attempt to mount a loopback network file system in mountcritremote will
fail.

Also add a progress message to mountcritlocal, for the sake of symmetry
with similar messages in mountcritremote and mountlate.
