This became a problem because #foundation-office:matrix.org has a
malformed create event with its `predecessor` set to a string instead of
a map.
The solution to this is, unfortunately, to do more shotgun parsing to
extract only the desired fields rather than trying to parse the entire
content every time. To prevent this kind of problem from happening
again, `RoomCreateEventContent` must only be used for creating new PDUs,
existing PDUs must be shotgun-parsed.
This gets rid of 3 instances of re-parsing the room version.
There's one place where we need the event ID of the room create event to
verify federation responses, so now we just look up the event ID at that
point instead.
And some supporting changes:
* crane: It removed its dependency on nixpkgs and made overrideToolchain
take a function for splicing reasons, but we're doing splicing
ourselves so we can just ignore the function argument. These changes
are in `flake.nix`.
* [NixOS/nixpkgs#347228][0]: linkerFor* were removed because the linker
no longer needs to be different in some edge cases. Based on the
diff of the PR that introduced this change, ccFor* are the proper
replacements. These changes are in `cross-compilation-env.nix` in the
compiler-and-linker-choosing section.
* [NixOS/nixpkgs#350299][1]: buildPlatform isn't at the top level
anymore, we have to go through stdenv now. These changes are in
`nix/shell.nix`.
* rocksdb: nixpkgs has 9.6.1 now so we need to upgrade our rust
library to use the matching version. These changes are in
`Cargo.toml`, `Cargo.lock`, `nix/pkgs/default/default.nix`, and
`cross-compilation-env.nix` in the linker flags section.

This will break backwards compatibility of configurations, but
ensures that a previously-configured setting won't get dropped
arbitrarily. Pretty much worth it, I think.
