- Try harder to normalize the exit status of the Tor process to the
standard-provided range. Fixes bug 16975; bugfix on every version
of Tor ever.
- Check correctly for windows socket errors in the workqueue
backend. Fixes bug 16741; bugfix on 0.2.6.3-alpha.
- Fix the behavior of crypto_rand_time_range() when told to consider times
before 1970. (These times were possible when running in a
simulated network environment where time()'s output starts at
zero.) Fixes bug 16980; bugfix on 0.2.7.1-alpha.

TestingDirAuthVoteHSDir[IsStrict], which suggested that a HSDir
required "ORPort connectivity". While this is true, it is in no
way unique to the HSDir flag. Of all the flags, only HSDirs need a
DirPort configured in order for the authorities to assign that
particular flag. Patch by "teor". Fixed as part of 14882; bugfix on 0.2.6.3-alpha.
o Minor bugfixes (relay):
- Ensure that worker threads actually exit when a fatal error or
shutdown is indicated. This fix doesn't currently affect the behaviour
of Tor, because Tor workers never indicates fatal error or shutdown except
in the unit tests. Fixes bug 16868; bugfix on 0.2.6.3-alpha.
o Minor bugfixes (correctness):
- When calling channel_free_list(), avoid calling smartlist_remove()
while inside a FOREACH loop. This partially reverts commit
17356fe7fd96af where the correct SMARTLIST_DEL_CURRENT was
incorrectly removed. Fixes bug 16924; bugfix on 0.2.4.4-alpha.
