0c6eabf088 Audit all of the "is the network turned off" checks.
DisableNetwork is a subset of net_is_disabled(), which is (now) a
subset of should_delay_dir_fetches().

Some of these changes are redundant with others higher or lower in
the call stack.  The ones that I think are behavior-relevant are
listed in the changes file.  I've also added comments in a few
places where the behavior is subtle.

Fixes bug 12062; bugfix on various versions.

0dc55fb247 Don't delay descriptor fetches when missing info needed for circuits
When we have fewer than 15 descriptors to fetch, we will delay the
fetch for a little while.  That's fine, if we can go ahead and build
circuits... but if not, it's a poor choice indeed.

Fixes bug 23985; bugfix on 0.1.1.11-alpha.

In 0.3.0.3-alpha, when we made primary guard descriptors necessary
for circuit building, this situation got worse.

14b0bba06e Use node counts in networks with all zero-bandwidths
When calculating the fraction of nodes that have descriptors, and all
all nodes in the network have zero bandwidths, count the number of nodes
instead.

3c03e237ab Remove an erroneous 0.5 in compute_weighted_bandwidths()
Back in 0.2.4.3-alpha (e106812a77), when we switched from using
double to using uint64 for selecting by bandwidth, I got the math
wrong: I should have used llround(x), or (uint64_t)(x+0.5), but
instead I wrote llround(x+0.5).  That means we would always round
up, rather than rounding to the closest integer

35746a9ee7 Comment-only change: annotate exit() calls.
Sometimes when we call exit(), it's because the process is
completely hopeless: openssl has a broken AES-CTR implementation, or
the clock is in the 1960s, or something like that.

But sometimes, we should return cleanly from tor_main() instead, so
that embedders can keep embedding us and start another Tor process.

I've gone through all the exit() and _exit() calls to annotate them
with "exit ok" or "XXXX bad exit" -- the next step will be to fix
the bad exit()s.

First step towards 23848.

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.

0417dae580 When IPv6 addresses have not been downloaded, use hard-coded address info
The microdesc consensus does not contain any IPv6 addresses.
When a client has a microdesc consensus but no microdescriptor, make it
use the hard-coded IPv6 address for the node (if available).

(Hard-coded addresses can come from authorities, fallback directories,
or configured bridges.)

If there is no hard-coded address, log a BUG message, and fail the
connection attempt. (All existing code checks for a hard-coded address
before choosing a node address.)
