Improve overflow checks in tv_udiff and tv_mdiff 
Validate that tv_usec inputs to tv_udiff and tv_mdiff are in range.

Do internal calculations in tv_udiff and tv_mdiff in 64-bit,
which makes the function less prone to integer overflow,
particularly on platforms where long and time_t are 32-bit,
but tv_sec is 64-bit, like some BSD configurations.

Check every addition and subtraction that could overflow.

b3b4ffce2e prop250: Add memory and disk state in new files 
This commit introduces two new files with their header.

"shared_random.c" contains basic functions to initialize the state and allow
commit decoding for the disk state to be able to parse them from disk.

"shared_random_state.c" contains everything that has to do with the state
for both our memory and disk. Lots of helper functions as well as a
mechanism to query the state in a synchronized way.

5fbd195918 Coverage hack for test_switch_id.sh 
This hack provides a way to make sure we can see coverage from
test-switch-id.  If you set OVERRIDE_GCDA_PERMISSIONS_HACK, we
temporarily make the .gcda files mode 0666 before we run the
test scripts, and then we set them to 0644 again afterwards.

That's necessary because the test_switch_id.sh script does a
setuid() to 'nobody' part way through, and drops the ability to
change its mind back.

94762e37b9 Use the Autoconf macro AC_USE_SYSTEM_EXTENSIONS 
The Autoconf macro AC_USE_SYSTEM_EXTENSIONS defines preprocessor macros
which turn on extensions to C and POSIX. The macro also makes it easier
for developers to use the extensions without needing (or forgetting) to
define them manually.

The macro can be safely used because it was introduced in Autoconf 2.60
and Tor requires Autoconf 2.63 and above.

c5e2f7b944 Bug 19406: Fix the unit tests to work with OpenSSL 1.1.x 
Just as it says on the tin.  Don't need to fully disable any tests and
reduce coverage either.  Yay me.

6ddef1f7e0 Bug 19406: OpenSSL removed SSL_R_RECORD_TOO_LARGE in 1.1.0. 
This is a logging onlu change, we were suppressing the severity down to
INFO when it occured (treating it as "Mostly harmless").  Now it is no
more.

b563a3a09d Bug 19406: OpenSSL made RSA and DH opaque in 1.1.0. 
There's accessors to get at things, but it ends up being rather
cumbersome.  The only place where behavior should change is that the
code will fail instead of attempting to generate a new DH key if our
internal sanity check fails.

Like the previous commit, this probably breaks snapshots prior to pre5.

86f0b80681 Bug 19406: OpenSSL changed the Thread API in 1.1.0 again. 
Instead of `ERR_remove_thread_state()` having a modified prototype, it
now has the old prototype and a deprecation annotation.  Since it's
pointless to add extra complexity just to remain compatible with an old
OpenSSL development snapshot, update the code to work with 1.1.0pre5
and later.

4c90cdc0e7 Coverity dislikes (double) (int/int). 
When you divide an int by an int and get a fraction and _then_ cast
to double, coverity assumes that you meant to cast to a double
first.

In my fix for -Wfloat-conversion in 493499a339, I
did something like this that coverity didn't like.

Instead, I'm taking another approach here.

Fixes CID 1232089, I hope.

53a3b39da1 Add -Wmissing-variable-declarations, with attendant fixes 
This is a big-ish patch, but it's very straightforward.  Under this
clang warning, we're not actually allowed to have a global variable
without a previous extern declaration for it.  The cases where we
violated this rule fall into three roughly equal groups:
  * Stuff that should have been static.
  * Stuff that was global but where the extern was local to some
    other C file.
  * Stuff that was only global when built for the unit tests, that
    needed a conditional extern in the headers.

The first two were IMO genuine problems; the last is a wart of how
we build tests.

8f2d2933f9 Use -Wdouble-promotion in GCC >= 4.6 
This warning triggers on silently promoting a float to a double.  In
our code, it's just a sign that somebody used a float by mistake,
since we always prefer double.

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.
