c985592874 prop140 clients now only try to get diffs from recent consensuses
Rationale: If it's a year old, the relay won't have a diff to it.

This is as specified in prop140

6beb7028d8 Do not BUG on missing sha3-as-signed field
This can happen if you've been running an earlier alpha on your
relay.  Instead, just ignore the entry.

These are mostly just identifier renames, except for one place in
routerparse.c where we switch to using a correct hash.

afa39cef6c Extract the consensus-only part of directory_get_from_dirserver
Right now it just sets an if-modified-since header, but it's about
to get even bigger.

This patch avoids changing indentation; the next patch will be
whitespace fixes.

3af9704e45 bug#22143/prop#140: in consdiffmgr, store and use digest-as-signed
We need to index diffs by the digest-as-signed of their source
consensus, so that we can find them even from consensuses whose
signatures are encoded differently.

c8baa9b783 bug#22143/prop#140: Use <n>,$d commands in diffs to remove signatures
In this patch I add support for "delete through end of file" in our
ed diff handler, and generate our diffs so that they remove
everything after in the consensus after the signatures begin.

90b840af60 control: Fix NULL pointer access in HS desc event
This was introduced 90562fc23a adding a code
path where we pass a NULL pointer for the HSDir fingerprint to the control
event subsystem. The HS desc failed function wasn't handling properly that
pointer for a NULL value.

Two unit tests are also added in this commit to make sure we handle properly
the case of a NULL hsdir fingerprint and a NULL content as well.

Fixes #22138

5494087ed7 Delete useless checks in confparse.c
config_parse_interval() and config_parse_msec_interval() were checking
whether the variable "ok" (a pointer to an int) was null, rather than
derefencing it.  Both functions are static, and all existing callers
pass a valid pointer to those static functions.  The callers do check
the variables (also confusingly named "ok") whose addresses they pass
as the "ok" arguments, so even if the pointer check were corrected to
be a dereference, it would be redundant.

Fixes #22103.

db86b9194d Break connection_dir_client_reached_eof() into smaller functions
This was a >630-line function, which doesn't make anybody happy.  It
was also mostly composed of a bunch of if-statements that handled
different directory responses differently depending on the original
purpose of the directory connection.  The logical refactoring here
is to move the body of each switch statement into a separate handler
function, and to invoke those functions from a separate switch
statement.

This commit leaves whitespace mostly untouched, for ease of review.
I'll reindent in the next commit.

90562fc23a hs: Trigger control event when client can't pick HSDir
Inform the control port with an HS_DESC failed event when the client is unable
to pick an HSDir. It's followed by an empty HS_DESC_CONTENT event. In order to
achieve that, some control port code had to be modified to accept a NULL HSDir
identity digest.

This commit also adds a trigger of a failed event when we are unable to
base64-decode the descriptor cookie.

Fixes #22042
