IP_MULTICAST_TTL Time to live for multicast datagrams. This option
takes an unsigned character as an argument. Its
value is the TTL that IP uses on outgoing multi-
cast datagrams. The default is 1.
IP_MULTICAST_LOOP Loopback for multicast datagrams. Normally multi-
cast datagrams are delivered to members on the
sending host (or sending zone). Setting the
unsigned character argument to 0 causes the oppo-
site behavior, meaning that when multiple zones
are present, the datagrams are delivered to all
zones except the sending zone.

…Simulacrum Simplify NodeHeader by avoiding slices in BTreeMaps with shared roots Simplify a complicated piece of code that creates slices of keys in node leaves.
…t-out, r=oli-obk Implement `?const` opt-out for trait bounds For now, such bounds are treated exactly the same as unprefixed ones in all contexts. [RFC 2632](rust-lang/rfcs#2632) does not specify whether such bounds are forbidden outside of `const` contexts, so they are allowed at the moment. Prior to this PR, the constness of a trait bound/impl was stored in `TraitRef`. Now, the constness of an `impl` is stored in `ast::ItemKind::Impl` and the constness of a bound in `ast::TraitBoundModifer`. Additionally, constness of trait bounds is now stored in an additional field of `ty::Predicate::Trait`, and the combination of the constness of the item along with any `TraitBoundModifier` determines the constness of the bound in accordance with the RFC. Encoding the constness of impls at the `ty` level is left for a later PR. After a discussion in \#wg-grammar on Discord, it was decided that the grammar should not encode the mutual exclusivity of trait bound modifiers. The grammar for trait bound modifiers remains `[?const] [?]`. To encode this, I add a dummy variant to `ast::TraitBoundModifier` that is used when the syntax `?const ?` appears. This variant causes an error in AST validation and disappears during HIR lowering. cc rust-lang#67794 r? @oli-obk
