d0fe199269 prop224: Implement decoding of superencrypted HS descriptor. 
[Consider starting review from desc_decrypt_all() ]

b2e37b87a7 prop224: Implement encoding of superencrypted HS descriptor. 
Also, relaxed the checks of encrypted_data_length_is_valid() since now
only one encrypted section has padding requirements and we don't
actually care to check that all the padding is there.

Consider starting code review from function encode_superencrypted_data().

870b5e2227 hs: Use AES-256 for v3 descriptor 
That key size is taken from proposal 224 thus specified in the protocol.

19cf074f4d hs: Remove private keys from hs_desc_plaintext_data_t. 
Since both the client and service will use that data structure to store the
descriptor decoded data, only the public keys are common to both.

Fixes #20572.

Also fix another couple of leaks.

025610612d prop224: Directory cache support 
This implements the proposal 224 directory descriptor cache store and lookup
functionalities. Furthermore, it merges the OOM call for the HSDir cache with
current protocol v2 and the new upcoming v3.

Add hs_cache.{c|h} with store/lookup API.

Closes #18572
