Reject Tor versions that contain non-numeric prefixes
strto* and _atoi64 accept +, -, and various whitespace before numeric
characters. And permitted whitespace is different between POSIX and Windows.

Fixes bug 21507 and part of 21508; bugfix on 0.0.8pre1.

67cec7578c Check for micro < 0, rather than checking "minor" twice.
Bug found with clang scan-build.  Fixes bug on f63e06d3dc.
Bug not present in any released Tor.

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.)

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

d73c671d6d policy_is_reject_star():
ome policies are default-reject, some default-accept.  But
policy_is_reject_star() assumed they were all default_reject.  Fix
that!

Also, document that policy_is_reject_star() treats a NULL policy as
empty. This allows us to simplify the checks in
parse_reachable_addresses() by quite a bit.

Fxes bug 20306; bugfix on 0.2.8.2-alpha.

aae034d13e Write a bunch of module documentation.
This commit adds or improves the module-level documenation for:

  buffers.c circuitstats.c command.c connection_edge.c control.c
  cpuworker.c crypto_curve25519.c crypto_curve25519.h
  crypto_ed25519.c crypto_format.c dircollate.c dirserv.c dns.c
  dns_structs.h fp_pair.c geoip.c hibernate.c keypin.c ntmain.c
  onion.c onion_fast.c onion_ntor.c onion_tap.c periodic.c
  protover.c protover.h reasons.c rephist.c replaycache.c
  routerlist.c routerparse.c routerset.c statefile.c status.c
  tor_main.c workqueue.c

In particular, I've tried to explain (for each documented module)
what each module does, what's in it, what the big idea is, why it
belongs in Tor, and who calls it.  In a few cases, I've added TODO
notes about refactoring opportunities.

I've also renamed an argument, and fixed a few DOCDOC comments.

e525f5697f Use protocols to see when EXTEND2 support exists.
(Technically, we could just remove extend2 cell checking entirely,
since all Tor versions on our network are required to have it, but
let's keep this around as an example of How To Do It.)

90a6fe318c Vote on 'proto' lines and include them after 'v' lines.
(Despite the increased size of the consensus, this should have
approximately zero effect on the compressed consensus size, since
the "proto" line should be completely implied by the "v" line.)

08d2d7c404 prop272: Believe that all routers are Valid and Running.
(We check consensus method when deciding whether to assume a node is
valid.  No need to check the consensus method for Running, since
we will never see a method before 13.)

0c26a6db7e prop250: Parse votes and consensus
One of the last piece that parses the votes and consensus in order to update
our state and make decision for the SR values.

We need to inform the SR subsystem when we set the current consensus because
this can be called when loaded from file or downloaded from other authorities
or computed.

The voting schedule is used for the SR timings since we are bound to the
voting system.
