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

This can happen if you've been running an earlier alpha on your

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.

38a13b91a8 Fix additional leaks in #22103 tests
test_options_validate_impl() incorrectly executed subsequent phases of
config parsing and validation after an expected error.  This caused
msg to leak when those later phases (which would likely produce errors
as well) overwrote it.

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

7b64f1773d Fix memory management for #22103 tests
Code movement in the commit introducings tests for #22103 uncovered a
latent memory management bug.

Refactor the log message checking from test_options_checkmsgs() into a
helper test_options_checklog().  This avoids a memory leak (and
possible double-free) in a test failure condition.

Don't reuse variables (especially pointers to allocated memory!) for
multiple unrelated purposes.

Fixes CID 1405778.

a91f948cca Add tests for #22103
Also factor out the error message comparisions from
test_options_validate_impl() into a separate function so it can check
for error messages in different phases of config parsing.

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.

3836d9481f Add unit tests for the NO_METHOD compressor
These required some special-casing, since some of the assumption
about real compression algorithms don't actually hold for the
identity transform.  Specifically, we had assumed:

  - compression functions typically change the lengths of their
    inputs.
  - decompression functions can detect truncated inputs
  - compression functions have detectable headers

None of those is true for the identity transformation.

1bc21111d8 Treat the identity transformation as another kind of compression.
This will allow us to treat NO_METHOD as a real compression method,
and to simplify code that currently does

   if (compressing) {
      compress
   } else {
      copy
   }

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
