new privileges (#12939).

c9f30c4512 systemd unit file: only allow tor to write to /var/lib/tor and /var/log/tor (#12751). 
The rest of the filesystem is accessible for reading only. Still, quoting
systemd.exec(5):

  Note that restricting access with these options does not extend to submounts
  of a directory that are created later on.

b40ac6808f Add the ed25519 ref10 code verbatim from supercop-20140622 
We might use libsodium or ed25519-donna later on, but for now, let's
see whether this is fast enough.  We should use it in all cases when
performance doesn't matter.

Add published line to @type bridge-network-status documents. 
This modifies the format of the bridge networkstatus documents produced
by the BridgeAuth. The new format adds a `published` line to the header
of the file, before the `flag-thresholds` line. This is done once per
networkstatus file that is written. The timestamp in the `published`
line is the standard ISO 8601 format (with a space as the separator)
used throughout the rest of tor.

051dd9c409 Remove the assigned-but-unused chosen_named_idx local variable 
It had been used in consensus method 1.  But now that 13 is the
minimum (see #10163), we don't need it around.

7c1143e11f Terser ways to sandbox-allow related filenames 
Using the *_array() functions here confused coverity, and was actually
a bit longer than we needed.  Now we just use macros for the repeated
bits, so that we can mention a file and a suffix-appended version in
one line.

d31bcc4b23 Tidy status handling in rendservice.c 
We had some code to fix up the 'status' return value to -1 on error
if it wasn't set, but it was unreachable because our code was
correct.  Tweak this by initializing status to -1, and then only
setting it to 0 on success.  Also add a goto which was missing: its
absence was harmless.

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; I like checking things where the logic for their not being
NULL is nontrivial.  Let's compromise, and make it obvious that this
field can't be NULL.

2a0a5fe612 Explicitly cast when dividing ints then implicitly casting to double. 
Coverity thinks that when we do "double x = int1/int2;", we probably
meant "double x = ((double)int1) / int2;".  In these cases, we
didn't.

7c61d10c6c Fix return value of tor_fd_seekend. 
Previously, we had documented it to return -1 or 0, when in fact
lseek returns -1 or the new position in the file.

This is harmless, since we were only checking for negative values
when we used tor_fd_seekend.
