    Peter Goodspeed-Niklaus authored
    * start sketching out a collation generation subsystem
    
    * invent a basic strategy for double initialization
    
    * clean up warnings
    
    * impl util requests from runtime assuming a context instead of a FromJob sender
    
    * implement collation generation algorithm from guide
    
    * update AllMessages in tests
    
    * fix trivial review comments
    
    * remove another redundant declaration from merge
    
    * filter availability cores by para_id
    
    * handle new activations each in their own async task
    
    * update guide according to the actual current implementation
    
    * add initialization to guide
    
    * add general-purpose subsystem_test_harness helper
    
    * write first handle_new_activations test
    
    * add test that handle_new_activations filters local_validation_data requests
    
    * add (failing) test of collation distribution message sending
    
    * rustfmt
    
    * broken: work on fixing sender test
    
    Unfortunately, for reasons that are not yet clear, despite the public key
    and checked data being identical, the signer is not producing an identical
    signature. This commit produces this output (among more):
    
    signing with  Public(c4733ab0bbe3ba4c096685d1737a7f498cdbdd167a767d04a21dc7df12b8c858 (5GWHUNm5...))

    signed payload:  [4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 10, 0, 0, 0, c7, e5, c0, 64, 7a, db, fe, 44, 81, e5, 51, 11, 79, 9f, a5, 63, 93, 94, 3c, c4, 36, c6, 30, 36, c2, c5, 44, a2, 1b, db, b7, 82, 3, 17, a, 2e, 75, 97, b7, b7, e3, d8, 4c, 5, 39, 1d, 13, 9a, 62, b1, 57, e7, 87, 86, d8, c0, 82, f2, 9d, cf, 4c, 11, 13, 14]
    checked payload: [4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 10, 0, 0, 0, c7, e5, c0, 64, 7a, db, fe, 44, 81, e5, 51, 11, 79, 9f, a5, 63, 93, 94, 3c, c4, 36, c6, 30, 36, c2, c5, 44, a2, 1b, db, b7, 82, 3, 17, a, 2e, 75, 97, b7, b7, e3, d8, 4c, 5, 39, 1d, 13, 9a, 62, b1, 57, e7, 87, 86, d8, c0, 82, f2, 9d, cf, 4c, 11, 13, 14]
    
    * fix broken test
    
    * collation function returns commitments hash
    
    It doesn't look like we use the actual commitments data anywhere, and
    it's not obvious if there are any fields of `CandidateCommitments`
    not available to the collator, so this commit just assigns them the
    entire responsibility of generating the hash.
    
    * add missing overseer impls
    
    * calculating erasure coding is polkadot's responsibility, not cumulus
    
    * concurrentize per-relay_parent requests
