0694263b75 Make round_to_next_multiple_of always round upwards.
Yes, even if it has to return a non-multiple.  This prevents us from
ever having a bug where we try to use it for allocation, and under-allocate.

8acccdbeac Add an util function to cast double to int64_t
Use it in the sample_laplace_distribution function to make sure we return
the correct converted value after math operations are done on the input
values.

Thanks to Yawning for proposing a solution.

dad5eb7e1f Tweak teor's and dgoulet's #13192 patches.
- Rewrite changes file.
 - Avoid float comparison with == and use <= instead.
 - Add teor's tor_llround(trunc(...)) back to silence clang warnings.
 - Replace tt_assert() with tt_i64_op() and friends.
 - Fix whitespace and a comment.

09cac24373 Handle edge cases in the round_*_to_next_multiple_of functions
Consistently check for overflow in round_*_to_next_multiple_of.

Check all round_*_to_next_multiple_of functions with expected values.
Check all round_*_to_next_multiple_of functions with maximal values.

Related to HS stats in #13192.

6d54bdbdcf Handle edge cases in laplace functions
Avoid division by zero.
Avoid taking the log of zero.
Silence clang type conversion warnings using round and trunc.
The existing values returned by the laplace functions do not change.

Add tests for laplace edge cases.
These changes pass the existing unit tests without modification.

915c7438a7 Add "ADD_ONION"/"DEL_ONION" and "GETINFO onions/*" to the controller.
These commands allow for the creation and management of ephemeral
Onion ("Hidden") services that are either bound to the lifetime of
the originating control connection, or optionally the lifetime of
the tor instance.

Implements #6411.

3f41318472 Add crypto_rand_int_range() and use it
Incidently, this fixes a bug where the maximum value was never used when
only using crypto_rand_int(). For instance this example below in
rendservice.c never gets to INTRO_POINT_LIFETIME_MAX_SECONDS.

  int intro_point_lifetime_seconds =
    INTRO_POINT_LIFETIME_MIN_SECONDS +
    crypto_rand_int(INTRO_POINT_LIFETIME_MAX_SECONDS -
                    INTRO_POINT_LIFETIME_MIN_SECONDS);

ba2485f7df Remove USE_OPENSSL_BASE64 and the associated code.
The alternative has been available since 2007, there's no way to
actually enable the ifdef, and it breaks on well formed but not OpenSSL
style inputs.

fa81508eb2 Use prctl() to have the kernel SIGTERM background processes on exit.
This uses a Linux-ism to attempt to always clean up background processes
if possible.  Note that it is not a catch-all, in that executables with
suid/sgid or elevated capabilities will have the prctl() attribute
stripped as part of the execve().

Resolves ticket 15471.

fda61e030e Implement "TOR_PT_EXIT_ON_STDIN_CLOSE".
Background processes spawned by Tor now will have a valid stdin.
Pluggable transports can detect this behavior with the aformentioned
enviornment variable, and exit if stdin ever gets closed.

7bed9dc73a Avoid double-parens in log_fn() messages on clang.
On clang (and elsewhere?) __PRETTY_FUNCTION__ includes parenthesized
argument lists.  This is clever, but it makes our old "%s(): " format
look funny.

- add the temporary micro revision file to the list of files to be removed on
  `make clean` just in case.
- fix indentation of the make rule to improve readability.

192ed94410 Use PTHREAD_CREATE_DETACHED macro instead of 1: fix Solaris crash
When calling pthread_attr_setdetachstate, we were using 1 as the
argument. But the pthreads documentation says that you have to say
PTHREAD_CREATE_DETACH, which on Solaris is apparently 0x40.  Calling
pthread_attr_setdetachstate with 1 crashes on Solaris with FLTBOUNDS.

(Because we're so late in the release cycle, I made the code define
PTHREAD_CREATE_DETACHED if it doesn't exist, so we aren't likely to
break any other platforms.)

This bug was introduced when we made threading mandatory in
0.2.6.1-alpha; previously, we had force-disabled threading on
Solaris.  See #9495 discussion.
