e3713f17fb node: Make node_supports_v3_rendezvous_point() also check for the key
It is not enough to look at protover for v3 rendezvous support but also we
need to make sure that the curve25519 onion key is present or in other words
that the descriptor has been fetched and does contain it.

Fixes #27797.

08e3b88f07 Split routerlist.c into 4 separate modules
There are now separate modules for:
    * the list of router descriptors
    * the list of authorities and fallbacks
    * managing authority certificates
    * selecting random nodes

7ace8d5a61 Assert that some trunnel _new() functions return non-NULL
The trunnel functions are written under the assumption that their
allocators can fail, so GCC LTO thinks they might return NULL.  In
point of fact, they're using tor_malloc() and friends, which can't
fail, but GCC won't necessarily figure that out.

Fixes part of #27772.

GCC got confused here with LTO enabled.

abaca3fc8c Revise networkstatus parsing code to use lengths
This way the networkstatus can be parsed without being
NUL-terminated, so we can implement 27244 and mmap our consensus objects.

617160895c Defer reporting directory bootstrap progress
Existing cached directory information can cause misleadingly high
bootstrap percentages.  To improve user experience, defer reporting of
directory information progress until at least one connection has
succeeded to a relay or bridge.

Closes ticket 27169.

eee62e13d9 Make control_event_bootstrap() return void
Simplify control_event_bootstrap() by making it return void again.  It
is currently a fairly complicated function, and it's made more
complicated by returning an int to signal whether it logged at NOTICE
or INFO.

The callers conditionally log messages at level NOTICE based on this
return value.  Change the callers to unconditionally log their verbose
human-readable messages at level INFO to keep NOTICE logs less
cluttered.

This partially reverts the changes of #14950.

33a0c619a8 Do not store cached_dir_t for consensus in RAM if not a dircache.
There are three reasons we use a cached_dir_t to hold a consensus:
  1. to serve that consensus to a client
  2. to apply a consensus diff to an existing consensus
  3. to send the consensus to a controller.

But case 1 is dircache-only.  Case 2 and case 3 both fall back to
networkstatus_read_cached_consensus().  So there's no reason for us
to store this as a client.  Avoiding this saves about 23% of our RAM
usage, according to our experiments last month.

This is, semantically, a partial revert of e5c608e535.

Fixes bug 27247; bugfix on 0.3.0.1-alpha.

2f6bc74914 router: Keep RSA onion public key in ASN.1 format
The OpenSSL "RSA" object is currently 408 bytes compares to the ASN.1 encoding
which is 140 for a 1024 RSA key.

We save 268 bytes per descriptor (routerinfo_t) *and* microdescriptor
(microdesc_t). Scaling this to 6000 relays, and considering client usually
only have microdescriptors, we save 1.608 MB of RAM which is considerable for
mobile client.

This commit makes it that we keep the RSA onion public key (used for TAP
handshake) in ASN.1 format instead of an OpenSSL RSA object.

Changes is done in both routerinfo_t and microdesc_t.

Closes #27246

c9de65f966 Add checks in get_net_param_from_list() for valid output domain.
This patch adds two assertions in get_net_param_from_list() to ensure
that the `res` value is correctly within the range of the output domain.

Hopefully fixes Coverity CID #1415721, #1415722, and #1415723.

63b4ea22af Move literally everything out of src/or
This commit won't build yet -- it just puts everything in a slightly
more logical place.

The reasoning here is that "src/core" will hold the stuff that every (or
nearly every) tor instance will need in order to do onion routing.
Other features (including some necessary ones) will live in
"src/feature".  The "src/app" directory will hold the stuff needed
to have Tor be an application you can actually run.

This commit DOES NOT refactor the former contents of src/or into a
logical set of acyclic libraries, or change any code at all.  That
will have to come in the future.

We will continue to move things around and split them in the future,
but I hope this lays a reasonable groundwork for doing so.
