c3a4201faa Add "internal" to some bootstrap statuses when no exits are available.
If the consensus does not contain Exits, Tor will only build internal
circuits. In this case, relevant statuses will contain the word "internal"
as indicated in the Tor control-spec.txt. When bootstrap completes,
Tor will be ready to handle an application requesting an internal
circuit to hidden services at ".onion" addresses.

If a future consensus contains Exits, exit circuits may become available.

Tor already notifies the user at "notice" level if they have no exits in
the consensus, and can therefor only build internal paths.

Consequential change from #13718.

e84e1c9745 More generic passphrase hashing code, including scrypt support
Uses libscrypt when found; otherwise, we don't have scrypt and we
only support openpgp rfc2440 s2k hashing, or pbkdf2.

Includes documentation and unit tests; coverage around 95%. Remaining
uncovered code is sanity-checks that shouldn't be reachable fwict.

1b40ea036f Stop silently skipping invalid args to setevents
Return an error when the second or later arguments of the
"setevents" controller command are invalid events. Previously we
would return success while silently skipping invalid events.

c9cac69ac6 Remove a dead check for errmsg in handle_control_authenticate
Coverity doesn't like doing NULL checks on things that can't be

NULL is nontrivial.  Let's compromise, and make it obvious that this
field can't be NULL.

9b4ac986cb Use tor_getpw{nam,uid} wrappers to fix bug 11946
When running with User set, we frequently try to look up our
information in the user database (e.g., /etc/passwd).  The seccomp2
sandbox setup doesn't let us open /etc/passwd, and probably
shouldn't.

To fix this, we have a pair of wrappers for getpwnam and getpwuid.
When a real call to getpwnam or getpwuid fails, they fall back to a
cached value, if the uid/gid matches.

(Granting access to /etc/passwd isn't possible with the way we
handle opening files through the sandbox.  It's not desirable either.)

f96400d9df bug10449: a dying owning controller makes Tor exit immediately
If you want a slow shutdown, send SIGNAL SHUTDOWN.

(Why not just have the default be SIGNAL QUIT?  Because this case
should only happen when an owning controller has crashed, and a
crashed controller won't be able to give the user any "tor is
shutting down" feedback, and so the user gets confused for a while.
See bug 10449 for more info)

e46de82c97 squash! Pass const uint64_t pointers, document array length.
Don't cast uint64_t * to const uint64_t * explicitly.  The cast is always
safe, so C does it for us.  Doing the cast explitictly can hide bugs if
the input is secretly the wrong type.
