17089302fd Stop trying to resolve our hostname so often
For example, we were doing a resolve every time we think about doing a
directory fetch. Now we reuse the cached answer in some cases.

Fixes bugs 1992 (bugfix on 0.2.0.20-rc) and 2410 (bugfix on
0.1.2.2-alpha).

99457ee776 Fix two more coverity-spotted leaks in master.
One is a probably-impossible leak if we fail to sign a consensus;
another occurs when we can't look up the user we're trying to chown
our sockets to.

f3835bcb37 Avoid null-pointer deref in pathbias_is_new_circ_attempt
Coverity is worried about this (CID 980653).  It hasn't happened in
testing, but we might as well make sure it can't happen.

719940df2b Fix a nigh-impossible overflow in cpuworker.c
When we compute the estimated microseconds we need to handle our
pending onionskins, we could (in principle) overflow a uint32_t if
we ever had 4 million pending onionskins before we had any data
about how onionskins take.  Nevertheless, let's compute it properly.

Fixes bug 8210; bugfix on 0.2.4.10. Found by coverity; this is CID
980651.

9b2bb901d7 Fix a null-deref-on-fail in unit tests
If geoip_format_bridge_stats() returned NULL when it should have
returned a string, we would have tried to deref NULL, and died.  Not
a big deal in the unit tests, but still worth fixing.

43d2f99d54 Suppress a coverity false positive in connection_edge_package_raw_inbuf
Coverity is worried that we're checking entry_conn in some cases,
but not in the case where we set entry_conn->pending_optimistic_data.

This commit should calm it down (CID 718623).

f12fafac5a Make hidden service authorization work again.
The refactoring in commit 471ab34032 wasn't complete enough: we
were checking the auth_len variable, but never actually setting it,
so it would never seem that authentication had been provided.

This commit also removes a bunch of unused variables from
rend_service_introduce, whose unusedness we hadn't noticed because
we were wiping them at the end of the function.

Fix for bug 8207; bugfix on 0.2.4.1-alpha.

ffd6e557cb Speed up the curve25519 unit test by doing fewer iterations
This test was accounting for about 2/3 of our unit tests' runtime,
even on systems with a fast curve25519.  No test should take so long.

92ea0b86de Refactor resolve_my_address() so logs are more accurate / helpful
It returns the method by which we decided our public IP address
(explicitly configured, resolved from explicit hostname, guessed from
interfaces, learned by gethostname).

Now we can provide more helpful log messages when a relay guesses its IP
address incorrectly (e.g. due to unexpected lines in /etc/hosts). Resolves
ticket 2267.

While we're at it, stop sending a stray "(null)" in some cases for the
server status "EXTERNAL_ADDRESS" controller event. Resolves bug 8200.

so let's have it in to make the code more readable.

8cdd8b8353 Fix numerous problems with Tor's weak RNG.
We need a weak RNG in a couple of places where the strong RNG is
both needless and too slow.  We had been using the weak RNG from our
platform's libc implementation, but that was problematic (because
many platforms have exceptionally horrible weak RNGs -- like, ones
that only return values between 0 and SHORT_MAX) and because we were
using it in a way that was wrong for LCG-based weak RNGs.  (We were
counting on the low bits of the LCG output to be as random as the
high ones, which isn't true.)

This patch adds a separate type for a weak RNG, adds an LCG
implementation for it, and uses that exclusively where we had been
using the platform weak RNG.
