Updated tor to 0.2.9.10.

Changes in version 0.2.9.10 - 2017-03-01
  Tor 0.2.9.10 backports a security fix for users who build Tor with
  the --enable-expensive-hardening option. It also includes fixes for
  some major issues affecting directory authorities, LibreSSL
  compatibility, and IPv6 correctness.

  The Tor 0.2.9.x release series is now marked as a long-term-support
  series.  We intend to backport security fixes to 0.2.9.x until at
  least January of 2020.

  o Major bugfixes (directory authority, 0.3.0.3-alpha):
    - During voting, when marking a relay as a probable sybil, do not
      clear its BadExit flag: sybils can still be bad in other ways
      too. (We still clear the other flags.) Fixes bug 21108; bugfix
      on 0.2.0.13-alpha.

  o Major bugfixes (IPv6 Exits, backport from 0.3.0.3-alpha):
    - Stop rejecting all IPv6 traffic on Exits whose exit policy rejects
      any IPv6 addresses. Instead, only reject a port over IPv6 if the
      exit policy rejects that port on more than an IPv6 /16 of
      addresses. This bug was made worse by 17027 in 0.2.8.1-alpha,
      which rejected a relay's own IPv6 address by default. Fixes bug
      21357; bugfix on commit 004f3f4e53 in 0.2.4.7-alpha.

  o Major bugfixes (parsing, also in 0.3.0.4-rc):
    - Fix an integer underflow bug when comparing malformed Tor
      versions. This bug could crash Tor when built with
      --enable-expensive-hardening, or on Tor 0.2.9.1-alpha through Tor
      0.2.9.8, which were built with -ftrapv by default. In other cases
      it was harmless. Part of TROVE-2017-001. Fixes bug 21278; bugfix
      on 0.0.8pre1. Found by OSS-Fuzz.

  o Minor features (directory authorities, also in 0.3.0.4-rc):
    - Directory authorities now reject descriptors that claim to be
      malformed versions of Tor. Helps prevent exploitation of
      bug 21278.
    - Reject version numbers with components that exceed INT32_MAX.
      Otherwise 32-bit and 64-bit platforms would behave inconsistently.
      Fixes bug 21450; bugfix on 0.0.8pre1.

  o Minor features (geoip):
    - Update geoip and geoip6 to the February 8 2017 Maxmind GeoLite2
      Country database.

  o Minor features (portability, compilation, backport from 0.3.0.3-alpha):
    - Autoconf now checks to determine if OpenSSL structures are opaque,
      instead of explicitly checking for OpenSSL version numbers. Part
      of ticket 21359.
    - Support building with recent LibreSSL code that uses opaque
      structures. Closes ticket 21359.

  o Minor bugfixes (code correctness, also in 0.3.0.4-rc):
    - Repair a couple of (unreachable or harmless) cases of the risky
      comparison-by-subtraction pattern that caused bug 21278.

  o Minor bugfixes (tor-resolve, backport from 0.3.0.3-alpha):
    - The tor-resolve command line tool now rejects hostnames over 255
      characters in length. Previously, it would silently truncate them,
      which could lead to bugs. Fixes bug 21280; bugfix on 0.0.9pre5.
