* mnt_new_fs() returns object with refcount=1
* mnt_free_fs() does not care about reference counter
* new functions mnt_ref_fs() and mnt_unref_fs()
* mnt_table_add_fs() and mnt_table_rem_fs() uses reference counter
* libmmnt_context uses reference counter for internal FS (as it could be
shared outside the context)
* backwardly incompatible change:
- FS could be deallocated after mnt_table_remove_fs()

sfdisk: make unhiding as complete as possible
It is unlikely anyone will ever need this, but I like idea commands being
complete. The partition id's that can be unhide after this change are;
Hidden HPFS/NTFS
Hidden W95 FAT32
Hidden W95 FAT32 (LBA)
Hidden W95 FAT16 (LBA)

unshare: add --mount-proc for pid namespaces
Based on patch from Mike Frysinger <vapier@gentoo.org>.
Mike Frysinger wrote:
When it comes to pid namespaces, it's also useful for /proc to reflect
the current namespace. Again, this is easy to pull off, but annoying
to force everyone to do it themselves. So let's add a --mount-proc to
do the magic for us. The downside is that this also implies creating
a mount namespace as mounting the new pid namespace /proc over top the
system one will quickly break all other processes on the system.

unshare: add --fork options for pid namespaces
The ability of unshare to launch a new pid namespace is a bit limited.
The first process in the namespace is expected to be the "init" for it.
When it's not, you get bad behavior.
For example, trying to launch a shell in a new pid namespace fails very
quickly:
$ sudo unshare -p dash
# uname -r
3.8.3
# uname -m
dash: 2: Cannot fork
# ls -ld /
dash: 3: Cannot fork
# echo $$
1324
For this to work smoothly, we need an init process to actively watch over
things. But forcing people to re-use an existing init or write their own
mini init is a bit overkill. So let's add a --fork option to unshare to
do this common bit of book keeping. Now we can do:
$ sudo unshare -p --fork dash
# uname -r
3.8.3
# uname -m
x86_64
# ls -ld /
drwxr-xr-x 22 root root 4096 May 4 14:01 /
# echo $$
