This allows invitations to work in the case that the invitee is already
in the group, which can happen if the group becomes split. Such an
invitation is automatically accepted, leading to the peers becoming
connected in the group and sharing peer lists.
Renamed a poorly named test, fixed up a few printf statements,
substituted some unsigned integers with fixed size counterparts,
and implemmented the auto_run_test.h fixture for the lossy and
lossless packet tests.
The file_saving_test.c was not included in the cmake list
and thus was ignored by travis and "make check". I found this
out while introducing ck_assert_msg into the integration test.
Furthermore, removed some variable width integers from encryptsave_test.c,
and the SRunner utilization. Implemmented ck_assert_msg, reorganized some
loops, and removed some longs in file_transfer_test.c.
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.
