Replace overlay_ranges with visible_ranges which can hold more than
three ranges (will be needed for floating panes); move the visible
ranges checks outside of tty_draw_line and rewrite it to fix issues with
partially-obscured wide characters. With Michael Grant.
Update mcast-proxy to HEAD
- Router Alert added to MLD and IGMP queries
- IGMP checksum fix and added bounds checks
- MLDv1 queries aligned with RFC 2710 (reference added)
- MLD upstream filtering aligned with IGMP; fixes for MLD unregistration
and IPv6 address tracking
- Safety/cleanup: socket validity checks, default IGMP switch case,
restricted file-local visibility, moved local prototypes

bn_const: add RFC 7919 primes
There is no intention to expose these via public API or to use them in TLS.
For now these will only be used for short-circuiting pointless expensive
computations in DH_check().
ok beck
Scapy special for DH_check()
The latest release of Scapy calls DH_check() on all the well-known
Diffie-Hellman parameters for RFCs 2409, 3526, and 7919. It does this
via pyca/cryptography at startup. Every single time. This is obviously
very expensive, due to our 64 MR rounds (which are complete overkill
now that we have BPSW). Instead of pondering the ideal number of rounds
for BPSW with FFDH, simply skip the check if the parameter matches a
well-known prime. These are known to be safe primes, so we can skip
those super-expensive and pointless checks without any risk.
This is only done for the public dh->p parameter. It could be further
optimized, but with the follow-up commit adding the RFC 7919 primes this
reduces the startup time to what it was before Scapy 2.7.0: < 1s.
Reverting from 64 MR rounds to BN_check_primes rounds, we would still
have ~8s startup time without this optimization, which isn't great for
an interactive tool.

bn regress: add test that double checks the RFC 2409 and 3526 primes
Also has code to check the RFC 7919 primes and run DH_check() once that
knows about these.
