Forward-port 0.2.8.11 notes (master)

ChangeLog

 Changes in version 0.3.0.1-alpha - 2016-??-??
+Changes in version 0.2.8.11 - 2016-12-08
+  Tor 0.2.8.11 backports fixes for additional portability issues that
+  could prevent Tor from building correctly on OSX Sierra, or with
+  OpenSSL 1.1. Affected users should upgrade; others can safely stay
+  with 0.2.8.10.
+
+  o Minor bugfixes (portability):
+    - Avoid compilation errors when building on OSX Sierra. Sierra began
+      to support the getentropy() and clock_gettime() APIs, but created
+      a few problems in doing so. Tor 0.2.9 has a more thorough set of
+      workarounds; in 0.2.8, we are just using the /dev/urandom and mach
+      monotonic time interfaces. Fixes bug 20865. Bugfix
+      on 0.2.8.1-alpha.
+
+  o Minor bugfixes (portability, backport from 0.2.9.5-alpha):
+    - Fix compilation with OpenSSL 1.1 and less commonly-used CPU
+      architectures. Closes ticket 20588.
+

   unusable after they left standby mode. It also backports fixes for
