Remove changes files that have already been merged in release-0.2.5

(This means that changes/* is now "everything that changed since
0.2.5.10".)

changes/13295

-  o Minor bugfixes:
-    - Disable sandbox name resolver cache when running tor-resolve:
-      tor-resolve doesn't use the sandbox code, and turning it on was
-      breaking attempts to do tor-resolve on a non-default server on
-      Linux. Fixes bug 13295; bugfix on 0.2.5.3-alpha.

changes/bufferevent_compilation

-  o Minor bugfixes:
-    - Fix compilation when building with bufferevents enabled. (This
-      configuration is still not expected to work, however.)
-      Fixes bugs 12438, 12474, 11578; bugfixes on 0.2.5.1-alpha and
-      0.2.5.3-alpha. Patches from Anthony G. Basile and Sathyanarayanan
-      Gunasekaran.

changes/bug1038-3

-  o Minor bugfixes:
-    - Warn and drop the circuit if we receive an inbound 'relay early'
-      cell. Those used to be normal to receive on hidden service circuits
-      due to bug 1038, but the buggy Tor versions are long gone from
-      the network so we can afford to resume watching for them. Resolves
-      the rest of bug 1038; bugfix on 0.2.1.19.

changes/bug11200-caching

-  o Major bugfixes:
-    - When Tor starts with DisabledNetwork set, it would correctly
-      conclude that it shouldn't try making circuits, but it would
-      mistakenly cache this conclusion and continue believing it even
-      when DisableNetwork is set to 0. Fixes the bug introduced by the
-      fix for bug 11200; bugfix on 0.2.5.4-alpha.
-

changes/bug12160

- o Bugfixes
-   - Correctly update the local mark on the controlling channel when changing
-     the address of an or_connection_t after the handshake.  Fixes bug #12160;
-     bugfix on 0.2.4.4-alpha.

changes/bug12602

-  o Minor bugfixes (portability):
-    - Compile correctly with builds and forks of OpenSSL (such as
-      LibreSSL) that disable compression. Fixes bug 12602; bugfix on
-      0.2.1.1-alpha. Patch from "dhill".
-

changes/bug12700

-  o Minor bugfixes:
-    - When logging information about an EXTEND2 or EXTENDED2 cell, log
-      their names correctly. Fixes part of bug 12700; bugfix on
-      0.2.4.8-alpha.
-
-  o Minor bugfixes:
-    - When logging information about a relay cell whose command we
-      don't recognize, log its command as an integer. Fixes part of
-      bug 12700; bugfix on 0.2.1.10-alpha.
-

changes/bug12718

-  o Minor bugfixes:
-    - Correct a confusing error message when trying to extend a circuit
-      via the control protocol but we don't know a descriptor or
-      microdescriptor for one of the specified relays. Fixes bug 12718;
-      bugfix on 0.2.3.1-alpha.

changes/bug12730-systemd-verify-config

-  o Distribution:
-    - Verify configuration file via ExecStartPre in the systemd unit file.
-      Patch from intrigeri; resolves ticket 12730.

changes/bug12731-systemd-no-run-as-daemon

-  o Distribution:
-    - Explicitly disable RunAsDaemon in the systemd unit file.
-      Our current systemd unit uses "Type = simple", so systemd does
-      not expect tor to fork. If the user has "RunAsDaemon 1" in their
-      torrc, then things won't work as expected. This is e.g. the case
-      on Debian (and derivatives), since there we pass
-      "--defaults-torrc /usr/share/tor/tor-service-defaults-torrc"
-      (that contains "RunAsDaemon 1") by default.
-      Patch by intrigeri; resolves ticket 12731.

changes/bug12830

-  o Documentation:
-    - Adjust the URLs in the README to refer to the new locations of
-      several documents on the website. Patch from Matt Pagan. Fixes
-      bug 12830.

changes/bug12848

-  o Major bugfixes (relay):
-    - Avoid queuing or sending destroy cells for circuit ID zero when
-      we fail to send a CREATE cell. Fixes bug 12848; bugfix on
-      0.0.8pre1. Found and fixed by "cypherpunks".

changes/bug12864

-  o Minor bugfixes:
-    - Restore the functionality of CookieAuthFileGroupReadable. Fixes bug
-      12864; bugfix on 0.2.5.1-alpha.
-
-  o Minor features:
-    - Add an ExtORPortCookieAuthFileGroupReadable option to make the
-      cookie file for the ExtORPort g+r by default.

changes/bug12878

-  o Documentation:
-    - Document 'reject6' and 'accept6' ExitPolicy entries. Resolves 
-      ticket 12878.

changes/bug12908

-  o Minor features:
-    - Warn about attempts to run hidden services and relays in the
-      same process: that's probably not a good idea. Closes ticket
-      12908.

changes/bug12948

-  o Major bugfixes:
-    - Resume expanding abbreviations for command-line options. The fix
-      for bug 4647 accidentally removed our hack from bug 586 that rewrote
-      HashedControlPassword to __HashedControlSessionPassword when it
-      appears on the commandline (which allowed the user to set her
-      own HashedControlPassword in the torrc file while the controller
-      generates a fresh session password for each run). Fixes bug 12948;
-      bugfix on 0.2.5.1-alpha.

changes/bug12996

-  o Minor bugfixes:
-    - Downgrade "Unexpected onionskin length after decryption" warning
-      to a protocol-warn, since there's nothing relay operators can do
-      about a client that sends them a malformed create cell. Resolves
-      bug 12996; bugfix on 0.0.6rc1.

changes/bug12997

-  o Minor features:
-    - Log more specific warnings when we get an ESTABLISH_RENDEZVOUS cell
-      on a cannibalized or non-OR circuit. Resolves ticket 12997.

changes/bug13071

-  o Minor bugfixes (relay):
-    - Escape all strings from the directory connection before logging them.
-      Fixes bug 13071; bugfix on 0.1.1.15. Patch from "teor".

changes/bug13081

-  o Compilation fixes:
-    - Make the nmake make files work again. Fixes bug 13081. Bugfix on 0.2.5.1-alpha. Patch
-      from "NewEraCracker".
