6675196afb Make tun interfaces perform auto-creation. This means that if a 
program opens /dev/tun# and tun# has not been SIOCIFCREATE'd already,
it will be SIOCIFCREATE'd automatically.  FreeBSD's tun interfaces
behave in a somewhat similar fashion.

42f6b6f836 Patches from Frank Kardel: 
- length was one off in names and secrets.
- add win 98 kludge but we keep it disabled for now.
- setup the authorization bit early so that we don't end up doing ppp
  negotiations without authorization.

59d3d6c274 Don't throw away the name and the secret lengths. This eliminates all the 
strlen() calls, and there was a whole bunch of them.

ca989d9a38 Use strcmp() instead of memcmp() because if we get passed a 0 length name 
and secret, we'll authenticate successfully! While there, rename passwd to
secret so that code looks nicer.

31144d9976 Convert ioctl code to use EPASSTHROUGH instead of -1 or ENOTTY for 
indicating an unhandled "command".  ERESTART is -1, which can lead to
confusion.  ERESTART has been moved to -3 and EPASSTHROUGH has been
placed at -4.  No ioctl code should now return -1 anywhere.  The
ioctl() system call is now properly restartable.

a180cee23b Pool deals fairly well with physical memory shortage, but it doesn't 
deal with shortages of the VM maps where the backing pages are mapped
(usually kmem_map).  Try to deal with this:

* Group all information about the backend allocator for a pool in a
  separate structure.  The pool references this structure, rather than
  the individual fields.
* Change the pool_init() API accordingly, and adjust all callers.
* Link all pools using the same backend allocator on a list.
* The backend allocator is responsible for waiting for physical memory
  to become available, but will still fail if it cannot callocate KVA
  space for the pages.  If this happens, carefully drain all pools using
  the same backend allocator, so that some KVA space can be freed.
* Change pool_reclaim() to indicate if it actually succeeded in freeing
  some pages, and use that information to make draining easier and more
  efficient.
* Get rid of PR_URGENT.  There was only one use of it, and it could be
  dealt with by the caller.
