config: Fix duplicate error message for nonlocal SocksPorts.
If `validate_only` is true, then just validate the configuration without warning
about it.  This way, we only emit warnings when the listener is actually opened.
(Otherwise, every time we parse the config we will might re-warn and we would
need to keep state; whereas the listeners are only opened once.)

 * FIXES #4019.

b867295ffd config: Parse ports at the start of options_validate()
There was a bug that got exposed with the removal of ORListenAddress. Within
server_mode(), we now only check ORPort_set which is set in parse_ports().

However, options_validate() is using server_mode() at the start to check if we
need to look at the uname but then the ORPort_set is unset at that point
because the port parsing was done just after. This commit fixes that.

b0e92634d8 Netflow record collapsing defense.
This defense will cause Cisco, Juniper, Fortinet, and other routers operating
in the default configuration to collapse netflow records that would normally
be split due to the 15 second flow idle timeout.

Collapsing these records should greatly reduce the utility of default netflow
data for correlation attacks, since all client-side records should become 30
minute chunks of total bytes sent/received, rather than creating multiple
separate records for every webpage load/ssh command interaction/XMPP chat/whatever
else happens to be inactive for more than 15 seconds.

The defense adds consensus parameters to govern the range of timeout values
for sending padding packets, as well as for keeping connections open.

The defense only sends padding when connections are otherwise inactive, and it
does not pad connections used solely for directory traffic at all. By default
it also doesn't pad inter-relay connections.

Statistics on the total padding in the last 24 hours are exported to the
extra-info descriptors.

c2d1d949de Use tor_compress_supports_method() before printing library versions.
This patch ensures that Tor checks if a given compression method is
supported before printing the version string when calling `tor
--library-versions`.

Additionally, we use the `tor_compress_supports_method()` to check if a
given version is supported for Tor's start-up version string, but here
we print "N/A" if a given compression method is unavailable.

f80a43d16f Stop ignoring hidden service key anonymity when first starting tor
Instead, refuse to start tor if any hidden service key has been used in
a different hidden service anonymity mode.

Fixes bug 20638; bugfix on 17178 in 0.2.9.3-alpha; reported by ahf.

The original single onion service poisoning code checked poisoning state
in options_validate, and poisoned in options_act. This was problematic,
because the global array of hidden services had not been populated in
options_validate (and there were ordrering issues with hidden service
directory creation).

This patch fixes this issue in rend_service_check_dir_and_add, which:
* creates the directory, or checks permissions on an existing directory, then
* checks the poisoning state of the directory, then
* poisons the directory.

When validating, only the permissions checks and the poisoning state checks
are perfomed (the directory is not modified).

8da24c99bd Split bridge functions into a new module.
This patch is just:
   * Code movement
   * Adding headers here and there as needed
   * Adding a bridges_free_all() with a call to it.

It breaks compilation, since the bridge code needed to make exactly
2 calls into entrynodes.c internals.  I'll fix those in the next
commit.

The client addr is essentially meaningless in this context (yes, it is
possible to explicitly `bind()` AF_LOCAL client side sockets to a path,
but no one does it, and there are better ways to grant that sort of
feature if people want it like using `SO_PASSCRED`).

41f96078c2 Refactor UseEntryNodes so the original configured value is preserved
Parse the value to UseEntryNodes_option, then set UseEntryNodes before
validating options.

This way, Authorities, Tor2web, and Single Onion Services don't write
spurious "UseEntryNodes 0" lines to their configs. Document the fact that
these tor configurations ignore UseEntryNodes in the manual page.

Also reorder options validation so we modify UseEntryNodes first, then
check its value against EntryNodes.

And silence a warning about disabled UseEntryNodes for hidden services
when we're actually in non-anonymous single onion service mode.

b560f852f2 Implement Prop #260: Single Onion Services
Add experimental OnionServiceSingleHopMode and
OnionServiceNonAnonymousMode options. When both are set to 1, every
hidden service on a tor instance becomes a non-anonymous Single Onion
Service. Single Onions make one-hop (direct) connections to their
introduction and renzedvous points. One-hop circuits make Single Onion
servers easily locatable, but clients remain location-anonymous.
This is compatible with the existing hidden service implementation, and
works on the current tor network without any changes to older relays or
clients.

Implements proposal #260, completes ticket #17178. Patch by teor & asn.

squash! fixup! fixup! fixup! fixup! fixup! fixup! fixup! fixup! fixup! fixup! fixup! fixup! fixup! Implement Prop #260: Single Onion Services

Redesign single onion service poisoning.

When in OnionServiceSingleHopMode, each hidden service key is poisoned
(marked as non-anonymous) on creation by creating a poison file in the
hidden service directory.

Existing keys are considered non-anonymous if this file exists, and
anonymous if it does not.

Tor refuses to launch in OnionServiceSingleHopMode if any existing keys
are anonymous. Similarly, it refuses to launch in anonymous client mode
if any existing keys are non-anonymous.

Rewrite the unit tests to match and be more comprehensive.
Adds a bonus unit test for rend_service_load_all_keys().

Count unix sockets when counting client listeners
Users can't run an anonymous client and non-anonymous single
onion service at the same time. We need to know whether we have
any client ports or sockets open to do this check.

When determining whether a client port (SOCKS, Trans, NATD, DNS)
is set, count unix sockets when counting client listeners. This
has no user-visible behaviour change, because these options are
set once and never read in the current tor codebase.

Don't count sockets when setting ControlPort_set, that's what
ControlSocket is for. (This will be reviewed in #19665.)

Don't count sockets when counting server listeners, because the code
that uses these options expects to count externally-visible ports.
(And it would change the behaviour of Tor.)
