AF_NATM support was removed before 5.5
Appletalk support was removed a while ago.  So was natm and hylink (if ever).
Let's mention MPLS instead.

Fix some more nasty stringyness in here by using asprintf instead of cruft.
gets rid of the second last use of the awful DECIMAL_SIZE.
Remove unused fields from the pipes.
Set cold to 1 before executing the DVACT_POWERDOWN handlers when halting or
rebooting a machine, like it is done in the hibernate case.

At least some USB host controller drivers rely on this to busy way instead
of sleeping.  Avoid a panic on macppc with an uhci(4) cardbus plugged in.

Eliminate some duplicated "mfctl cr29, rN" instructions.

SBus glue for qlw(4) for sparc.  Untested.
Make use of SSL_IS_DTLS, SSL_USE_EXPLICIT_IV, SSL_USE_SIGALGS and
SSL_USE_TLS1_2_CIPHERS.

Largely based on OpenSSL head.
remove some #if 0 code. we don't need any more reminders that we're using
a not quite appropriate data structure. ok jsing
More KNF.
oops, auto-read config only *after* we have a way to print out errors.
Also zap bad lines completely.

Don't add potentially nasty stderr uses to dead CRYPTO_dbg_mem functions.
But do use the abort(), which we are hoping all future vendors will move
towards the more modern "do not flush streams"; hint hint, if you didn't
do that already, there are grave risks because much software brings risk
without that behaviour. We didn't cause the change.. POSIX did...

Add option -S to have dump(8) only estimate backup size and number of tapes
required (from NetBSD).
