Closes ticket 27765
This commit also changes the appveyor file to a unified line ending
style, since the old one was pretty confused. Use "-b" to see the
real differences.
In hs_config.c, we do validate the permission of the hidden service directory
but we do not try to create it. So, in the event that the directory doesn't
exists, we end up in the loading key code path which checks for the
permission and possibly creates the directory. On failure, don't BUG() since
there is a perfectly valid use case for that function to fail.

.retain() would allocating a Vec of billions of integers and check them
one at a time to separate the supported versions from the unsupported.
This leads to a memory DoS.
Closes ticket 27206. Bugfix on e6625113c9.
Before 0.3.3.1-alpha, we would exit() in this case immediately. But
now that we leave tor_main() more conventionally, we need to make
sure we restore things so as not to cause a double free.
Fixes bug 27708; bugfix on 0.3.3.1-alpha.
Since we use a 32-bit approximation for millisecond conversion here,
we can't expect so much precision.
Fixes part of bug 27139; bugfix on 0.3.4.1-alpha.
Multiply-then-divide is more accurate, but it runs into trouble when
our input is above INT32_MAX/numerator. So when our value is too
large, do divide-then-multiply instead.
Fixes part of bug 27139; bugfix on 0.3.4.1-alpha.
We use an optimized but less accurate formula for converting coarse
time differences to milliseconds on 32-bit OSX platforms, so that we
can avoid 64-bit division.
The old numbers were off by 0.4%. The new numbers are off by .006%.
This should make the unit tests a bit cleaner, and our tolerances a
bit closer.
It's possible for a unit test to report success via its pipe, but to
fail as it tries to clean up and exit. Notably, this happens on a
leak sanitizer failure.
Fixes bug 27658; bugfix on 0.2.2.4-alpha when tinytest was
introduced.
