We should avoid recursion, as it makes reasoning about stack growth
harder. This tool shows (currently) 4 (non-tail) recursive functions, at
least 2 of which are easy to fix.
Don't know why codes with macro dosen't work.
As it's only a few expensive, just code it without macro for now.
\#if (MIN_LOGGER_LEVEL == LOG_TRACE) || (MIN_LOGGER_LEVEL == LOG_DEBUG)
fprintf(stderr, "[%s] %s:%d(%s) %s\n", strlevel, file, line, func, message);

Reduced by, e.g.:
* `file_transfer_test`: 33% of the `clock_gettime` calls.
* `tox_many_test`: 53% of the `clock_gettime` calls.
Other tests will see similar improvements. Real world applications will
be closer to 40-50% improvement, since tox_many_test has 100 nodes, while
file_transfer_test has 2 nodes.
This allows Tox to contain additional data on top of Messenger, making
Messenger not necessarily the most top-level object. E.g. groups are
built on Messenger and currently awkwardly void-pointered into it to
pretend there is no cyclic dependency.
It turns out, `unix_time` is also monotonic, and is used as such, so I've
renamed the new functions to `mono_time_*`.

```
00:01 <@irungentoo> the idea used to be that the unix_time() function
could go backward in time but I think I might have started using it like
if it could not after I changed it so that it would never go back in time
```
Rules:
1. Constants are uppercase names: THE_CONSTANT.
2. SUE[1] types start with an uppercase letter and have at least one
lowercase letter in it: The_Type, THE_Type.
3. Function types end in "_cb": tox_friend_connection_cb.
4. Variable and function names are all lowercase: the_function.
This makes it easier for humans reading the code to determine what an
identifier means. I'm not convinced by the enum type name change, but I
don't know a better rule. Currently, a lot of enum types are spelled like
constants, which is confusing.

This is needed for libvpx to work on android.
This also means that we can upload our test binaries to an android device
and actually run them, now that libcheck is no longer a blocker.
The first round some tests will fail and others will segfault. The second
round, still some will fail, but the third round it might pass. At some
point, tests will pass.
The reason for this is that tests assume a lot about which ports they are
given, and also toxcore's default port range has too few ports to run all
tests in parallel. These issues will be fixed in future PRs.
Also, add an auto-test for bootstrap and for LAN discovery.
Bootstrap is never tested otherwise, and LAN discovery is a prerequisite
for everything else. Having these two tests lets us rule out or identify
LAN discovery as a possible cause for test failures.
Also reduce number of people in conference to 5, because on Circle CI the
test times out trying to connect more than 6 or 7 people. The persistent
conferences PR will improve this so we can set it much higher then.
Since trusty has more up-to-date packages, we can remove some of the
custom install code. Also, we're not using hstox at the moment, so there
is no need to slow down the builds for now.
