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

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 ?)
