Ruslan Ermilov 434dbbb396 Fix the following bugs: 
- In ifc_name2unit(), disallow leading zeroes in a unit.

  Exploit: ifconfig lo01 create

- In ifc_name2unit(), properly handle overflows.  Otherwise,
  either of two local panic()'s can occur, either because
  no interface with such a name could be found after it was
  successfully created, or because the code will bogusly
  assume that it's a wildcard (unit < 0 due to overflow).

  Exploit: ifconfig lo<overflowed_integer> create

- Previous revision made the following sequence trigger
  a KASSERT() failure in queue(3):

  Exploit: ifconfig lo0 destroy; ifconfig lo0 destroy

  This is because IFC_IFLIST_REMOVE() is always called
  before ifc->ifc_destroy() has been run, not accounting
  for the fact that the latter can fail and leave the
  interface operating (like is the case for "lo0").
  So we ended up calling LIST_REMOVE() twice.  We cannot
  defer IFC_IFLIST_REMOVE() until after a call to
  ifc->ifc_destroy() because the ifnet may have been
  removed and its memory has been freed, so recover from
  this by re-inserting the ifnet in the cloned interfaces
  list if ifc->ifc_destroy() indicates a failure.
