If /proc/#/fd points to a path which has component removed, fuser
will complain like "Cannot stat file /proc/29322/fd/16: Not a
directory". Looks like it can be disabled just like commit 898dc70a1f
did.

--host is used for the system where the compiled code will run.
--target is not the correct system to look that up.

pstree compiles with SE Linux
pstree failed to compile with SE Linux enabled because one of the
scontext was missed and without it enabled the bug doesn't appear.
pstree is now re-worked so scontext is defined as a dummy meaning
most of the code except the reall SE Linux specific stuff is compilied
meaning this sort of thing shouldn't happen too much again.

pstree finds orphans
Commit 26f9b6c1553d021c0bf9dd85f0647dc6e210948d while fixing the missing
root pid problem introduced another problem where PIDs are out of order.
A process that has a lower PID than its PPID would appear twice with
the tree breaking in strange ways.
We now scan the entire process tree first then perform two checks
if PID==1 is missing add it
if a process has no parent, then make it a child of PID==1, either the
real one or the faked one made in step 1
As this is done after all procsses are found, we don't get the previous
breakage.

fuser -m regression
While fuser -m /boot worked, fuser -m /dev/blah would show everything.
This was because the filesystem for /dev was added as a target, not the
filesystem /dev/blah.
This simple fix suggested by SF user hanpt works well.

3 fixes for Cygwin
The attached patch fixes three issues of fuser on Cygwin.:
- Cygwin does not support /proc/net/unix. The call to fill_unix_cache
always generates an error message that /proc/net/unix couldn't be
found, so the patch disables the call for Cygwin. An alternative
fix would be to avoid the error message entirely.
- `ls /dev' on Cygwin only lists manually added entries to /dev, not the
default files suported by Cygwin internally. Also,
/proc/$PID/mountinfo doesn't exist up to Cygwin 1.7.11. This
breaks fuser when using the _LISTS_H option.
- If you don't include lists.h, the code in check_dir doesn't work well.
st.st_ino is never set to 0, so the timeout(stat, ...) is never
called. Also, thedev never gets a valid value in this case, but it's
used subsequently for comparisons.

2 Fixes for Debian Bug#623425
Both patches are by Jonathan Nieder <jrnieder@gmail.com>
Ever since psmisc 22.4 (2007-04-08), "killall <path>" compares
the target of the /proc/<pid>/exe link to <path> when comparison
of inode numbers fails. But the code to do this has two problems:
- readlink does not NUL-terminate, but we use strcmp to
compare strings. Probably this hasn't been a problem so far
because (1) the on-stack buffer happened to have zeroes in the
right places or (2) some implementations of readlink might
happen to NUL-terminate their result when convenient anyway.
- it relies on PATH_MAX to determine the size of the buffer,
so the code fails to build from source on platforms (like the
Hurd) that have no global PATH_MAX.
Fix both by using a buffer of size strlen("<path>") + 1 and comparing
the link target to <path> with memcmp after checking that it fit in
the buffer.
For consistency with the surrounding code, the pid is considered not
to match if malloc or readlink fails.
---------------
The Hurd has most of the expected /proc/<pid> hierarchy but no
/proc/self. Without this change, running "sleep 10 & killall sleep"
on that platform produces the confusing message:
/proc is empty (not mounted ?)
