Remove fgets() compatbility function and related tests.
This patch removes the `tor_fgets()` wrapper around `fgets(3)` since it
is no longer needed. The function was created due to inconsistency
between the returned values of `fgets(3)` on different versions of Unix
when using `fgets(3)` on non-blocking file descriptors, but with the
recent changes in bug #21654 we switch from unbuffered to direct I/O on
non-blocking file descriptors in our utility module.

We continue to use `fgets(3)` directly in the geoip and dirserv module
since this usage is considered safe.

This patch also removes the test-case that was created to detect
differences in the implementation of `fgets(3)` as well as the changes
file since these changes was not included in any releases yet.

See: https://bugs.torproject.org/21654

Use tor_fgets() instead of fgets().
This patch changes our use of fgets() to tor_fgets() for more consistent
error handling across different versions of the C library.

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.

4f8086fb20 Enable -Wnull-dereference (GCC >=6.1), and fix the easy cases
This warning, IIUC, means that the compiler doesn't like it when it
sees a NULL check _after_ we've already dereferenced the
variable. In such cases, it considers itself free to eliminate the
NULL check.

There are a couple of tricky cases:

One was the case related to the fact that tor_addr_to_in6() can
return NULL if it gets a non-AF_INET6 address.  The fix was to
create a variant which asserts on the address type, and never
returns NULL.

00ffccd9a6 Another clang analyzer complaint wrt HT_GENERATE
We're calling mallocfn() and reallocfn() in the HT_GENERATE macro
with the result of a product.  But that makes any sane analyzer
worry about overflow.

This patch keeps HT_GENERATE having its old semantics, since we
aren't the only project using ht.h.  Instead, define a HT_GENERATE2
that takes a reallocarrayfn.

0e97c8e23e Siphash-2-4 is now our hash in nearly all cases.
I've made an exception for cases where I'm sure that users can't
influence the inputs.  This is likely to cause a slowdown somewhere,
but it's safer to siphash everything and *then* look for cases to
optimize.

This patch doesn't actually get us any _benefit_ from siphash yet,
since we don't really randomize the key at any point.

b7d8a1e141 Report complete directory request statistics on bridges.
When we wrote the directory request statistics code in August 2009, we
thought that these statistics were only relevant for bridges, and that
bridges should not report them.  That's why we added a switch to discard
relevant observations made by bridges.  This code was first released in
0.2.2.1-alpha.

In May 2012 we learned that we didn't fully disable directory request
statistics on bridges.  Bridges did report directory request statistics,
but these statistics contained empty dirreq-v3-ips and dirreq-v3-reqs
lines.  But the remaining dirreq-* lines have always been non-empty.  (We
didn't notice for almost three years, because directory-request statistics
were disabled by default until 0.2.3.1-alpha, and all statistics have been
removed from bridge descriptors before publishing them on the metrics
website.)

Proposal 201, created in May 2012, suggests to add a new line called
bridge-v3-reqs that is similar to dirreq-v3-reqs, but that is published
only by bridges.  This proposal is still open as of December 2013.

Since October 2012 we're using dirreq-v3-resp (not -reqs) lines in
combination with bridge-ips lines to estimate bridge user numbers; see
task 8462.  This estimation method has superseded the older approach that
was only based on bridge-ips lines in November 2013.  Using dirreq-v3-resp
and bridge-ips lines is a workaround.  The cleaner approach would be to
use dirreq-v3-reqs instead.

This commit makes bridges report the same directory request statistics as
relays, including dirreq-v3-ips and dirreq-v3-reqs lines.  It makes
proposal 201 obsolete.

cb54e44587 Fix a number of issues with the #5040 code.
- Don't leak if a transport proxy sends us a TRANSPORT command more
  than once.

- Don't use smartlist_string_isin() in geoip_get_transport_history().
  (pointed out by Nick)

- Use the 'join' argument of smartlist_join_strings() instead of
  trying to write the separator on our own.
  (pointed out by Nick)

- Document 'ext_or_transport' a bit better.
  (pointed out by Nick)

- Be a bit more consistent with the types of the values of 'transport_counts'.

a3e0a87d95 Completely refactor how FILENAME_PRIVATE works
We previously used FILENAME_PRIVATE identifiers mostly for
identifiers exposed only to the unit tests... but also for
identifiers exposed to the benchmarker, and sometimes for
identifiers exposed to a similar module, and occasionally for no
really good reason at all.

Now, we use FILENAME_PRIVATE identifiers for identifiers shared by
Tor and the unit tests.  They should be defined static when we
aren't building the unit test, and globally visible otherwise. (The
STATIC macro will keep us honest here.)

For identifiers used only by the unit tests and never by Tor at all,
on the other hand, we wrap them in #ifdef TOR_UNIT_TESTS.

This is not the motivating use case for the split test/non-test
build system; it's just a test example to see how it works, and to
take a chance to clean up the code a little.
