7456677a50 Make outter (plaintext) layer of HS desc conform to prop224.
This basically means changing the 'encrypted' field to 'superencrypted'.

c468df3961 Don't warn about absent guard state when none expected.
Self-testing circuits don't use guards, and nobody uses guards when
UseEntryGuards is disabled.

Fixes bug 21007; bug not in any released Tor.

Update the fallback directory mirror list in December 2016
Replace the 81 remaining fallbacks of the 100 originally introduced
in Tor 0.2.8.3-alpha in March 2016, with a list of 177 fallbacks
(123 new, 54 existing, 27 removed) generated in December 2016.

Resolves ticket 20170.

d978216dea Fix parsing bug with unecognized token at EOS
In get_token(), we could read one byte past the end of the
region. This is only a big problem in the case where the region
itself is (a) potentially hostile, and (b) not explicitly
nul-terminated.

This patch fixes the underlying bug, and also makes sure that the
one remaining case of not-NUL-terminated potentially hostile data
gets NUL-terminated.

Fix for bug 21018, TROVE-2016-12-002, and CVE-2016-1254

ae89d9745d Revert ticket 20982 changes.
They broke stem, and breaking application compatibility is usually a
bad idea.

This reverts commit 6e10130e18,
commit 78a13df158, and
commit 62f52a888a.

We might re-apply this later, if all the downstream tools can handle
it, and it turns out to be useful for some reason.

f3d056ab16 clarify debug-level log while initializing entropy
I got confused when I saw my Tor saying it was opening a file
that doesn't exist. It turns out it isn't opening it, it's just
calling open() on it and then moving on when it's not there.

2a00110e5b Revert "Stop checking whether environ is declared."
This reverts commit 954eeda619.

Apparently, OpenBSD is what expects you to declare environ
yourself.  So 19142 is a wontfix.

deb8bcadce 271: Algorithm tweak to allow multiple entry guards.
Previously, we had NumEntryGuards kind of hardwired to 1.  Now we
have the code (but not the configuarability) to choose randomly from
among the first N primary guards that would work, where N defaults
to 1.

Part of 20831 support for making NumEntryGuards work again.

e044b4f8ce Support restrictive ENTRYNODES configurations correctly.
Since we already had a separate function for getting the universe of
possible guards, all we had to do was tweak it to handle very the
GS_TYPE_RESTRICTED case.

fc7751a989 Rewrite state transition logic in entry_guards_note_success()
asn found while testing that this function can be reached with
GUARD_STATE_COMPLETE circuits; I believe this happens when
cannibalization occurs.

The added complexity of handling one more state made it reasonable
to turn the main logic here into a switch statement.

2e2f3a4d99 Add a separate, non-fractional, limit to the sampled guard set size.
Letting the maximum sample size grow proportionally to the number of
guards defeats its purpose to a certain extent.  Noted by asn during
code review.
