d0fe199269 prop224: Implement decoding of superencrypted HS descriptor.
[Consider starting review from desc_decrypt_all() ]

b2e37b87a7 prop224: Implement encoding of superencrypted HS descriptor.
Also, relaxed the checks of encrypted_data_length_is_valid() since now
only one encrypted section has padding requirements and we don't
actually care to check that all the padding is there.

Consider starting code review from function encode_superencrypted_data().

bb602f6197 prop224: Prepare for superencrypted HS descriptors.
- Refactor our HS desc crypto funcs to be able to differentiate between
  the superencrypted layer and the encrypted layer so that different
  crypto constants and padding is used in each layer.

- Introduce some string constants.

- Add some comments.

3336f26e60 hs: Avoid a strlen(NULL) if descriptor is not found in cache
Instead of returning 404 error code, this led to a NULL pointer being used and
thus a crash of tor.

Fixes #21471

02e05bd74d When examining descriptors as a dirserver, reject ones with bad versions
This is an extra fix for bug 21278: it ensures that these
descriptors and platforms will never be listed in a legit consensus.

c4f2faf301 Don't atoi off the end of a buffer chunk.
Fixes bug 20894; bugfix on 0.2.0.16-alpha.

We already applied a workaround for this as 20834, so no need to
freak out (unless you didn't apply 20384 yet).

a0ef3cf088 Prevent int underflow in dirvote.c compare_vote_rs_.
This should be "impossible" without making a SHA1 collision, but
let's not keep the assumption that SHA1 collisions are super-hard.

This prevents another case related to 21278.  There should be no
behavioral change unless -ftrapv is on.

1afc2ed956 Fix policies.c instance of the "if (r=(a-b)) return r" pattern
I think this one probably can't underflow, since the input ranges
are small.  But let's not tempt fate.

This patch also replaces the "cmp" functions here with just "eq"
functions, since nothing actually checked for anything besides 0 and
nonzero.

Related to 21278.

194e31057f Avoid integer underflow in tor_version_compare.
Fix for TROVE-2017-001 and bug 21278.

(Note: Instead of handling signed ints "correctly", we keep the old
behavior, except for the part where we would crash with -ftrapv.)
