3f41318472 Add crypto_rand_int_range() and use it
Incidently, this fixes a bug where the maximum value was never used when
only using crypto_rand_int(). For instance this example below in
rendservice.c never gets to INTRO_POINT_LIFETIME_MAX_SECONDS.

  int intro_point_lifetime_seconds =
    INTRO_POINT_LIFETIME_MIN_SECONDS +
    crypto_rand_int(INTRO_POINT_LIFETIME_MAX_SECONDS -
                    INTRO_POINT_LIFETIME_MIN_SECONDS);

0f31080d63 Stop checking for torrc state files generated by very old Tor versions
These haven't worked in so long that if you had a state file of this
kind, the guards in it would be so old that you wouldn't use them
anyway.

b101f4e98c Control: getinfo entry-guards report down-since
If the guard unreachable_since variable was set, the status "up" was
reported which is wrong. This adds the "down" status followed by the
unreachable_since time value.

Fixes #14184

4cb59ceb8e Only retry connecting to configured bridges
After connectivity problems, only try connecting to bridges which
are currently configured; don't mark bridges which we previously
used but are no longer configured.  Fixes 14216.  Reported by
and fix provided by arma.

33df3e37ff Allow two ISO times to appear in EntryGuardDownSince.
When I made time parsing more strict, I broke the
EntryGuardDownSince line, which relied on two concatenated ISO times
being parsed as a single time.

Fixes bug 14136. Bugfix on 7984fc1531. Bug not in any released
version of Tor.

fb68f50761 Lower the delay before saving guard status to disk
"Maybe this time should be reduced, since we are considering
guard-related changes as quite important? It would be a pity to
settle on a guard node, then close the Tor client fast and lose that
information."

Closes 12485.

ff42222845 Improve DIRINFO flags' usage comments
Document usage of the NO_DIRINFO and ALL_DIRINFO flags clearly in functions
which take them as arguments. Replace 0 with NO_DIRINFO in a function call
for clarity.

(By default, it overrides the number of directory guards too.)

79c875ecdc Would-be fix for bug 7733: learn bridge ID from descriptor
If somebody has configured a client to use a bridge without setting
an identity digest (not recommended), learn the identity digest from
whatever bridge descriptor we have downloaded or have in our cache.

6ab10a5466 Make num_bridges_usable work properly.
My first implementation was broken, since it returned "whether there
is one bridge" rather than "how many bridges."

Also, the implementation for the n_options_out feature in
choose_random_entry_impl was completely broken due to a missing *.

This is meant to be a better bug 9229 fix -- or at least, one more

router_retry_directory_downloads() only on the first bridge descriptor.
