389d2b6e21 Fix a refcount race with the vmspace structure. In order to prevent 
resource starvation we clean-up as much of the vmspace structure as we
can when the last process using it exits.  The rest of the structure
is cleaned up when it is reaped.  But since exit1() decrements the ref
count it is possible for a double-free to occur if someone else, such as
the process swapout code, references and then dereferences the structure.
Additionally, the final cleanup of the structure should not occur until
the last process referencing it is reaped.

This commit solves the problem by introducing a secondary reference count,
calling 'vm_exitingcnt'.  The normal reference count is decremented on exit
and vm_exitingcnt is incremented.  vm_exitingcnt is decremented when the
process is reaped.  When both vm_exitingcnt and vm_refcnt are 0, the
structure is freed for real.

a3b5a4369c Employ the unused bytes after the disklabel in the second sector. This makes 
it possible to make UFS1_ONLY and UFS2_ONLY versions which fit inside the
traditional 16 sectors.

UFS1_AND_UFS2 still needs another 150 bytes to work, and that is probably
not within our reach, ever.

a child process is used instead, they will (necessarily) use a separate
