8a4bba06d2 Rename crypto_digest_all, and digests_t.
They are no longer "all" digests, but only the "common" digests.

Part of 17795.

This is an automated patch I made with a couple of perl one-liners:

  perl -i -pe 's/crypto_digest_all/crypto_common_digests/g;' src/*/*.[ch]
  perl -i -pe 's/\bdigests_t\b/common_digests_t/g;' src/*/*.[ch]

af116081f9 Make the no-assertions-during-coverage check into a configure option

I'm doing branch coverage specifically.

We use sensible parameters taken from common sources, and no longer
have dynamic DH groups as an option, but it feels prudent to have

5f7df92571 Remove support for unsigned time_t
We've never actually tested this support, and we should probably assume
it's broken.

To the best of my knowledge, only OpenVMS has this, and even on
OpenVMS it's a compile-time option to disable it.  And I don't think
we build on openvms anyway.  (Everybody else seems to be working
around the 2038 problem by using a 64-bit time_t, which won't expire
for roughly 292 billion years.)

be841f77aa Compatibility defines should be used for LibreSSL.
LibreSSL doesn't use OpenSSL_version (it uses the older SSLeay_version
API), but it reports a major version number as 2 in
OPENSSL_VERSION_NUMBER. Instead of fudging the version check, for now,
let's just check if we're using LibreSSL by checking the version number
macro exists, and use compatibility defines unconditionally when we
detect LibreSSL.

110765f556 Use get_interface6_via_udp_socket_hack() properly in _list().
When _list() is called with AF_UNSPEC family and fails to enumerate
network interfaces using platform specific API, have it call
_hack() twice to find out IPv4 and/or IPv6 address of a machine Tor
instance is running on. This is correct way to handle this case
because _hack() can only be called with AF_INET and AF_INET6 and
does not support any other address family.

35bbf2e4a4 Prop210: Add schedules for simultaneous client consensus downloads
Prop210: Add attempt-based connection schedules

Existing tor schedules increment the schedule position on failure,
then retry the connection after the scheduled time.

To make multiple simultaneous connections, we need to increment the
schedule position when making each attempt, then retry a (potentially
simultaneous) connection after the scheduled time.

(Also change find_dl_schedule_and_len to find_dl_schedule, as it no
longer takes or returns len.)

Prop210: Add multiple simultaneous consensus downloads for clients

Make connections on TestingClientBootstrapConsensus*DownloadSchedule,
incrementing the schedule each time the client attempts to connect.

Check if the number of downloads is less than
TestingClientBootstrapConsensusMaxInProgressTries before trying any
more connections.

07cca627ea Fix backtrace compilation on FreeBSD
On FreeBSD backtrace(3) uses size_t instead of int (as glibc does). This
causes integer precision loss errors when we used int to store its
results.

The issue is fixed by using size_t to store the results of backtrace(3).

The manual page of glibc does not mention that backtrace(3) returns
negative values. Therefore, no unsigned integer wrapping occurs when its
result is stored in an unsigned data type.
