c0024edd26 Remove two vestigial MaxDownloadTries checks from directory.c
These are no longer meaningful, since there's no longer an upper
limit to how many times (in the exponential-backoff world) one can
retry a download.  download_status_is_ready() didn't check these any
more, and neither do we.

5b55e15707 Remove all the old max_delay logic.
We had tests for it, but it was always INT_MAX.

bf74194f57 fixup! Remove the old ("deterministic") download schedule.
Un-indent a block.

I'm doing this as a separate fixup commit to make review simpler.

e0049ef022 Remove the old ("deterministic") download schedule.
We haven't meant to use it since we introduced the random
exponential schedule.

Closes ticket 23814.

19a4abf2a9 Make sure bridges are definitely running before delaying directory fetches
Retry directory downloads when we get our first bridge descriptor
during bootstrap or while reconnecting to the network. Keep retrying
every time we get a bridge descriptor, until we have a reachable bridge.

Stop delaying bridge descriptor fetches when we have cached bridge
descriptors. Instead, only delay bridge descriptor fetches when we
have at least one reachable bridge.

Fixes bug 24367; bugfix on 0.2.0.3-alpha.

Stop checking cached bridge descriptors for usable bridges
Stop checking for bridge descriptors when we actually want to know if
any bridges are usable. This avoids potential bootstrapping issues.
Fixes bug 24367; bugfix on 0.2.0.3-alpha.

Stop stalling when bridges are changed at runtime. Stop stalling when
old bridge descriptors are cached, but they are not in use.

380a95116a relay: Avoid extra LOG_NOTICE for every new descriptor batch
Commit 56c5e282a7 suppressed that same log
statement in directory_info_has_arrived() for microdescriptors so do the same
for the descriptors. As the commit says, we already have the bootstrap
progress for this.

c4a56ed5c2 Silence a warning about failed descriptor uploads.
Due to #23662 this can happen under natural causes and does not disturb
the functionality of the service. This is a simple 0.3.2 fix for now,
and we plan to fix this properly in 0.3.3.

eb429232ef Make dir servers include a "Date:" http header more often
Directory servers now include a "Date:" http header for response
codes other than 200. Clients starting with a skewed clock and a
recent consensus were getting "304 Not modified" responses from
directory authorities, so without a Date header the client would
never hear about a wrong clock.

Stop relays calling directory_fetches_from_authorities on dir downloads
This change refactors find_dl_schedule() to only call dependent functions
as needed. In particular, directory_fetches_from_authorities() only needs
to be called on clients.

Stopping spurious directory_fetches_from_authorities() calls on every
download on public relays has the following impacts:
* fewer address resolution attempts, particularly those mentioned in 21789
* fewer descriptor rebuilds
* fewer log messages, particularly those limited in 20610

Fixes 23470 in 0.2.8.1-alpha.
The original bug was introduced in commit 35bbf2e as part of prop210.

93a8ed3b83 Make clients wait to refresh bridges when they have a recent descriptor
But when clients are just starting, make them try each bridge a few times
before giving up on it.

These changes make the bridge download schedules more explicit: before
17750, they relied on undocumented behaviour and specific schedule
entries. (And between 17750 and this fix, they were broken.)

Fixes 23347, not in any released version of tor.

97249c4f5e Make bridge clients download bridge descriptors immediately
The download schedule tells Tor to wait 15 minutes before downloading
bridge descriptors. But 17750 made Tor ignore that and start immediately.
Since we fixed 17750, Tor waits 15 minutes for bridge client bootstrap,
like the schedule says.

This fixes the download schedule to start immediately, and to try each
bridge 3 times in the first 30 seconds. This should make bridge bootstraps
more reliable.

Fixes 23347.
