Currently when the peer collapses its rwnd, we mark packets to be retransmitted
and use the must_retran flags like we do when a PMTU collapses to retransmit the
collapsed packets. However this causes a problem with some middle boxes that
play with the rwnd to control flow. As soon as the rwnd increases we start resending
which may be not even a rtt.. and in fact the peer may have gotten the packets. Which
means we gratuitously retransmit packets we should not.
The fix here is to make sure that a rack time has passed before retransmitting the packets.
This makes sure that the rwnd collapse was real and the packets do need retransmission.

A while back Hans optimized the LRO code. This is great but one
optimization he did degrades the timestamp precision so that
all flushed LRO entries end up with the same LRO timestamp
if there is not a hardware timestamp. The intent of the LRO timestamp
is to get as close to the time that the packet arrived as possible. Without
the LRO queuing this works out fine since a binuptime is taken and then
the rx_common code is called. But when you go through the queue path
you end up *not* updating the M_LRO_TSTMP fields.
Another issue in the LRO code is several places that cause packet reordering. In
general TCP can handle reordering but it can cause extra un-needed retransmission
as well as other oddities. We will fix all of the reordering problems.
Lets fix this so that we restore the precision to the timestamp.

Currently make.py has a hack to add the cross-build headers to the
include search path when bootstrapping bmake on Linux (but not macOS).
This is a bit of an abuse of these headers, and e9ba1fd5ed was not
prepared for this, since sys/bitcount.h won't exist in that instance (it
gets copied into WORLDTMP during the legacy build). Work around this
until we can wean the bmake bootstrap off using these headers by not
including sys/bitcount.h when it doesn't exist.

During a discussion with someone working on NFS-over-TLS
for a non-FreeBSD platform, we agreed that a single server
daemon for TLS handshakes could become a bottleneck when
an NFS server first boots, if many concurrent NFS-over-TLS
connections are attempted.
This patch modifies the kernel RPC code so that it can
handle multiple rpc.tlsservd daemons. A separate commit

daemon.

For now it is read-only, but eventually the cycle that goes over
all fragments should be refactored and this MIB should also become
read/write.
This MIB will allow SNMP daemons to implement MIB-II ipReasmTimeout MIB
straightfoward. Right now net-snmp compilation is broken by 1922eb3e9c.
The base system bsnmpd is not broken just because it ignored PR_SLOWTIMO,
and thus always returned incorrectly doubled value for ipReasmTimeout.

There is a problem still left after the fixes to REAP_KILL_PROC. The
handling of the stopping signals by sig_suspend_threads() can occur
outside the stopping process context by tdsendsignal(), and it uses
mostly the same mechanism of aborting sleeps as suspension. In other
words, it badly interacts with thread_single(SINGLE_ALLPROC).
But unlike single threading from the process context, we cannot wait by
sleep for other single threading requests to pass, because we own
spinlock(s).
Fix this by moving both the thread_single(p2, SINGLE_ALLPROC), and the
signalling, to the threaded taskqueue which cannot be single-threaded
itself.

RB_ROTATE_LEFT (and it symmetric twin) modify the rb-tree, adjusting
pointers so that what started as a proper tree ends up a proper
tree. When two consecutive rotations move the same node up the tree,
some of the pointers changed in the first rotation are immediately
changed again in the second - namely, the pointer from the rising node
to its new parent, and the pointer from that parent back to the rising
node. This change removes from RB_ROTATE macros the responsibility for
managing those two pointers, and leaves it to the code that calls for
rotations to fix up those pointers afterward. That drops a comparison
and a pair of assignments from every INSERT_COLOR or REMOVE_COLOR call
that ends in a double rotation.
A side-effect of this change is that the SWAP_CHILD macro must take as
a parameter a pointer to the node that is changing children, where it
is now computed from the old child. Since this macro is called in a
couple of places besides the RB_ROTATE macros, those calls are also
affected.

FreeBSD introduced VersionAddendum for the server as a local change in
2001 in commit 933ca70f8f and later extended it to the client in
commit 9e2cbe04ff.
In 2012 upstream added support for server VersionAddendum, in commit
23528816dc10. They do not support it for the client.
The argument for supporting this in the client is not nearly as strong
as for the server, so retire this option to reduce the scope of our
local patch set. This also avoids some cases of conflicts in ssh_config
during update, as a user's configuration would typically follow the
commented-out default VersionAddendum value.
