f2a344e397 Downgrade IP version warnings to avoid filling logs
Downgrade logs and backtraces about IP versions to
info-level. Only log backtraces once each time tor runs.

tor-0.2.8.1-alpha.

Reported by "sysrqb" and "Christian", patch by "teor".

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.

42e131e9ac Fix a segfault during startup
If unix socket was configured as listener (such as a ControlSocket or a
SocksPort unix socket), and tor was started as root but not configured
to switch to another user, tor would segfault while trying to string
compare a NULL value.  Fixes bug 18261; bugfix on 0.2.8.1-alpha. Patch

3b8216f215 Use fascist firewall and ClientUseIPv4 for bridge clients
Bridge clients ignore ClientUseIPv6, acting as if it is always 1.
This preserves existing behaviour.

Make ClientPreferIPv6OR/DirPort auto by default:
 * Bridge clients prefer IPv6 by default.
 * Other clients prefer IPv4 by default.
This preserves existing behaviour.

2d33d192fc Add ClientUseIPv4 and ClientPreferIPv6DirPort torrc options
ClientUseIPv4 0 tells tor to avoid IPv4 client connections.
ClientPreferIPv6DirPort 1 tells tor to prefer IPv6 directory connections.

Refactor policy for IPv4/IPv6 preferences.

Fix a bug where node->ipv6_preferred could become stale if
ClientPreferIPv6ORPort was changed after the consensus was loaded.

Update documentation, existing code, add unit tests.

fd399ec850 Remove Windows specific data type usage
The Tor code base already contains usage of setsockopt(2) with an int as
their option value without problems.

2d2312d989 Conform to the type signature of setsockopt(2)
According to the POSIX standard the option value is a pointer to void
and the option length a socklen_t. The Windows implementation makes the
option value be a pointer to character and the option length an int.

Casting the option value to a pointer to void conforms to the POSIX
standard while the implicit cast to a pointer to character conforms to
the Windows implementation.

The casts of the option length to the socklen_t data type conforms to
the POSIX standard. The socklen_t data type is actually an alias of an
int so it also conforms to the Windows implementation.

port is in host order (addr is tor_addr_t, endianness is abstracted).

915c7438a7 Add "ADD_ONION"/"DEL_ONION" and "GETINFO onions/*" to the controller.
These commands allow for the creation and management of ephemeral
Onion ("Hidden") services that are either bound to the lifetime of
the originating control connection, or optionally the lifetime of
the tor instance.

Implements #6411.
