Nick Mathewson efadebf7c3 Make the chance for priority inversion thread-specific
Instead of choosing a lower-priority job with a 1/37 chance, have
the chance be 1/37 for half the threads, and 1/2147483647 for the
other half.  This way if there are very slow jobs of low priority,
they shouldn't be able to grab all the threads when there is better
work to do.

Nick Mathewson 10e0bff4ca Add support for multi-priority workqueues
Each piece of queued work now has an associated priority value; each
priority goes on a separate queue.

With probability (N-1)/N, the workers will take work from the highest
priority nonempty queue.  Otherwise, they'll look for work in a
queue of lower priority.  This behavior is meant to prevent
starvation for lower-priority tasks.

Nick Mathewson e111cfcd54 Restore openssl and libscrypt includes in test_crypto_slow.c
This reverts part of commit 706c44a6ce.

It was a mistake to remove these includes: they were needed on
systems where we have openssl 1.1.0 *and* libscrypt, and where we
were validating the one against the other.

Fixes bug 22892; bugfix on 0.3.1.1-alpha.

Nick Mathewson dfc0614840 Only disable -Wfloat-conversion on mingw when it exists.
The 22081 fix disabled -Wfloat-conversion, but -Wfloat-conversion
didn't exist in every relevant mingw; it was added in GCC 4.9.x some
time, if the documentation can be trusted.

Bug not in any released version of tor.

Nick Mathewson 5361032219 Fix -Wfloat-conversion C warnings on mingw in clamp_double_to_int64.
We just have to suppress these warnings: Mingw's math.h uses gcc's
__builtin_choose_expr() facility to declare isnan, isfinite, and
signbit.  But as implemented in at least some versions of gcc,
__builtin_choose_expr() can generate type warnings even from
branches that are not taken.

Nick Mathewson 88666d0482 Adjust unit tests to account for fix to bug 22753.
Our mock network put all the guards on the same IPv4 address, which
doesn't fly when we start applying EnforceDistinctSubnets.  So in
this commit, I disable EnforceDistinctSubnets when running the old
guard_restriction_t test.

This commit also adds a regression test for #22753.

Nick Mathewson 665baf5ed5 Consider the exit family when applying guard restrictions.
When the new path selection logic went into place, I accidentally
dropped the code that considered the _family_ of the exit node when
deciding if the guard was usable, and we didn't catch that during
code review.

This patch makes the guard_restriction_t code consider the exit
family as well, and adds some (hopefully redundant) checks for the
case where we lack a node_t for a guard but we have a bridge_info_t
for it.

Alexander Færøy c239b2fc9c Fix crash in LZMA module when the Sandbox is enabled.
This patch fixes a crash in our LZMA module where liblzma will allocate

Nick Mathewson f367453cb5 Mark descriptors as undownloadable when dirserv_add_() rejects them
As of ac2f6b608a in 0.2.1.19-alpha,
Sebastian fixed bug 888 by marking descriptors as "impossible" by
digest if they got rejected during the
router_load_routers_from_string() phase. This fix stopped clients
and relays from downloading the same thing over and over.

But we never made the same change for descriptors rejected during
dirserv_add_{descriptor,extrainfo}.  Instead, we tried to notice in
advance that we'd reject them with dirserv_would_reject().

This notice-in-advance check stopped working once we added
key-pinning and didn't make a corresponding key-pinning change to
dirserv_would_reject() [since a routerstatus_t doesn't include an
ed25519 key].

So as a fix, let's make the dirserv_add_*() functions mark digests
as undownloadable when they are rejected.

Fixes bug 22349; I am calling this a fix on 0.2.1.19-alpha, though
you could also argue for it being a fix on 0.2.7.2-alpha.
