Also, added some #defines to make symbols visible that are in BSD but not
in UNIX. Solaris needs these, since it's fairly strict with its symbol
visibility in system headers.
* Moved PAIR to toxav, where it's used (but really this should die).
* Replace most MIN calls with typed `min_*` calls. Didn't replace the
ones where the desired semantics are unclear. Moved the MIN macro to
the one place where it's still used.
* Avoid assignments in `while` loops. Instead, factored out the loop body
into a separate `bool`-returning function.
* Use named types for callbacks (`_cb` types).
* Avoid assignments in `if` conditions.
* Removed `MAKE_REALLOC` and expanded its two calls. We can't have
templates in C, and this fake templating is ugly and hard to analyse
and debug (it expands on a single line).
* Moved epoll system include to the .c file, out of the .h file.
* Avoid assignments in expressions (`a = b = c;`).
* Avoid multiple declarators per struct member declaration.
* Fix naming inconsistencies.
* Replace `net_to_host` macro with function.
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
```
Also, renamed simple_conference_test to conference_simple_test so it's
sorted together with the other conference tests.
Next step is to use run_auto_test.h for the conference test.
These display some idea, but the tests are not implemented correctly. We
will need to implement the idea correctly later, but for now we can't use
these.
This triggers a code path in Persistent Group Chats that causes a memory
leak. I'm adding this test now, so that we don't merge PGC without fixing
the memory leak first.
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.
This caused us to build everything 2-4 times, now we only build it 1-2
times (depending on selection of static/shared builds). The disadvantage
is that now it's more up to the reviewer to ensure modularity (we still
catch it in the bazel build, though).
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.
Instead of hard-erroring when we don't find dependencies, we just don't
build the things requested and print a warning. This is less annoying to
users because we enable a bunch of things by default. This way, we can at
least build something with the default "cmake" invocation.
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.
