dd7c999617 Make unix sockets work with the linux seccomp2 sandbox again 
I didn't want to grant blanket permissions for chmod() and chown(),
so here's what I had to do:
   * Grant open() on all parent directories of a unix socket
   * Write code to allow chmod() and chown() on a given file only.
   * Grant chmod() and chown() on the unix socket.

0cdeac77e0 Don't chmod/chown unix sockets if their permissions are already ok 
This is a part of a fix for 18253; bugfix on 0.2.8.1-alpha.

Alternatively, we could permit chmod/chown in the sandbox, but I
really don't like giving the sandbox permission to alter
permissions.

725e0c76e3 Permit setrlimit, prlimit, prlimit64 calls. 
We call setrlimit under some circumstances, and it can call prlimit
and prlimit64 under the hood.

Fixes bug 15221.

36ad65a7d1 When using open() to make sure we created a dir, close the fd afterwards 
Found by coverity. Not in any released Tor. Fixes CID 1355640.

Also, don't check for fd correctness with assert(fd).  You need to
assert (fd >= 0).

d8b93b31a0 hs: Do not close desc fetch conn. if we can't pick an HSDir 
Launching 7 descriptor fetches makes a connection to each HSDir that is 6
and the seventh one fails to pick an HSDir because they are all being used
already so it was killing all pending connections at once.

Fixes #15937

edeba3d472 simplify rend_cache_store_status_t back to a boolean 
it used to be a tri-state, but now it's just a bi-state, so we can
take out all the machinery like the enum.

dc500c8cb4 rip out rend_id_is_in_interval()

5390296338 rip out hid_serv_acting_as_directory() 
When we made HidServDirectoryV2 always 1, we removed the situation
where a relay could choose not to be an HSDir. Now simplify the
rest of the code to reflect this decision.

(We have to remove two apparently unrelated free() calls in the unit
tests, since they used to free stuff that we created as a side effect
of calling router_get_my_routerinfo(), and now we no longer call that.)

e167910fce rip out hid_serv_responsible_for_desc_id() 
This simplifies relay behavior, because the relay offers the hsdir
functionality independent of whether the directory authorities have
decided this relay is suitable for clients to use yet.

Implements ticket 18332.

25fa21802f Move Automake options to configure.ac

future changes.

ef31c8862f Add changes file for 18448; refactor 
(I've made it so FreeBSD || FreeBSD_kernel is enough to ensure that
we think you might have ipfw, and so that the logic is all in one
place.)

db263442af enable and test transproxy on FreeBSD derivatives #18448 
The transproxy feature is only enabled when __FreeBSD__ is defined, and
only regular FreeBSD does that.  Change this to __FreeBSD_kernel__ which
is defined on derivatives as well.

This enables the relevant options/validate__transproxy test on FreeBSD
derivatives.

e2202146d1 Update default fallback directories for 0.2.8.2-alpha (Feb 2016) 
Allow fallback directories which have been stable for 7 days
to work around #18050, which causes relays to submit descriptors
with 0 DirPorts when restarted. (Particularly during Tor version
upgrades.)

Ignore low fallback directory count in alpha builds.
Set the target count to 50.
