472b62bfe4 Uglify scheduler init logic to avoid crash on startup. 
Otherwise, when we authority try to do a self-test because of
init-keys, if that self-test can't be launched for whatever reason and
so we close the channel immediately, we crash.

Yes, this a silly way for initialization to work.

4903ab1caa Avoid frequent strcmp() calls for AccountingRule 
Generally, we don't like to parse the same thing over and over; it's
best IMO to do it once at the start of the code.

4d0ad34a92 Avoid division by zero in circuitstats pareto 
In circuit_build_times_calculate_timeout() in circuitstats.c, avoid dividing
by zero in the pareto calculations.

If either the alpha or p parameters are 0, we would divide by zero, yielding
an infinite result; which would be clamped to INT32_MAX anyway. So rather
than dividing by zero, we just skip the offending calculation(s), and
use INT32_MAX for the result.

Division by zero traps under clang -fsanitize=undefined-trap -fsanitize-undefined-trap-on-error.

ff8fe38a2f Stop spurious clang shallow analysis null pointer errors 
Avoid 4 null pointer errors under clang shallow analysis (the default when
building under Xcode) by using tor_assert() to prove that the pointers
aren't null. Resolves issue 13284 via minor code refactoring.

801f4d4384 Fix a double-free in failing case of handle_control_authenticate. 
Bugfix on ed8f020e205267e6270494634346ab68d830e1d8; bug not in any
released version of Tor.  Found by Coverity; this is CID 1239290.

[Yes, I used this commit message before, in 58e813d0fc.
Turns out, that fix wasn't right, since I didn't look up a
screen. :P ]

e84e1c9745 More generic passphrase hashing code, including scrypt support 
Uses libscrypt when found; otherwise, we don't have scrypt and we
only support openpgp rfc2440 s2k hashing, or pbkdf2.

Includes documentation and unit tests; coverage around 95%. Remaining
uncovered code is sanity-checks that shouldn't be reachable fwict.
