add veb-port kstats to count which of the many reasons a packet was dropped
this adds them to the per cpu mem on each port that the refcnt
"hazards" are on.
Drop MODTCL_CONFIG and MODTK_CONFIG.
Replace with equivalents in the only ports affected:
math/graphviz and math/R.
Tcl/Tk-dependent ports normally need the location,
not the full path to the config files.

Mechanical rename of prefix_adjout to adjout_prefix.
All the things for the Adj-RIB-Out handling should use adjout_ as prefix.
So both the struct and the various functions are renamed. This makes it
clearer what belongs to the adjout code.
OK tb@
Introduce an adjout_attr object that decouples some of the common data
from the prefix_adjout. This helps to reduce the memory footprint by
around 20% in large IXP setups.
The size of struct prefix_adjout is critical since we allocate very many
of those. e.g. 250k prefixes * 750 peer = 187mio objects. Every byte saved
makes a big difference.

Add a get-clipboard option which when enabled (the default is off) uses
the same mechanism as palette requests to request clipboard from the
terminal and forward to the requesting pane. Remove the now-redundant
forward-to-pane ability from "refresh-client -l". GitHub issue 4275.
rpki-client: convert mft.c to opaque ASN1_STRING
Mostly more of the same. In addition the comparison functions can use
ASN1_STRING_cmp() instead of doing most of it by hand. The additional
type check this introduces is fine since the ASN.1 template ensures
that. Annotate a spot where we fail to ensure that the unused bits
octet is zero, thus libcrypto's misdesign introduces a few bits of
malleability for every hash that ends in zero bits. This will be easier
to fix later.

use per cpu refs in the input path instead of one refcnt per port.
passing packets into tpmr relies on taking a ref from an smr critical
section so the tprm_port struct can be used while interacting with
the larger network stack because you can't sleep while in an smr
critical section and the network stack has sleeping points.
this is fine, but it's atomic ops against the same refcnt in the
one tpmr_port struct that can be running in parallel on all the
softnet threads. this means the cacheline under this refcnt gets
pulled around a lot, which in turn affects performance.
to compensate for this loss in performance, this diff adds per cpu
refcnts that act as a proxy to the tpmr_port refcnt. this effectively
hashes the softnet threads into individual refcnts on separate cache
lines.
unfortunately, softnet threads can move between cpus because the
network stack has sleeping points. this prevents us from using the

previously aggr (and trunk) would swap the if_input handler on their
port interfaces to intercept packets and make them appear to be
received by aggr, but this relied on the net lock to coordinate and
ensure the references to everything were safe. making aggr safe to
call without the netlock meant using refcnts to ensure the aggr_port
struct would stay alive while it's being used, but this means a
couple of atomic operations were added to every packet going through
aggr.

let the ether_port ref api have the caller carry local state for the port
this means ether_input will have a value on the stack that the port
drivers can use to keep track of a reference with, rather than
having to rely on implicit state (eg, which cpu they're running on)
which can change (eg, maybe there's rwlocks in the network stack).
Remove redundant program name logging in vmd(8).
The log.c init function already configures __progname as a default
log message prefix. No need to include it explicitly anymore.
