This inverts the truthiness of the return value. Previously, 0 meant
`true` and -1 meant `false`. Now, `true` (1) means `true` and `false` (0)
means `false`.

* 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.

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.

The Family stuff in toxcore is a big mess. I'm sure I saw a bunch of bugs
on the way, but I'm not verifying that code now, so the bugs stay.

Even if that means rejecting packets from ourselves if our IP is not a
"LAN" IP.
|
|
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.

This changes only code, no string literals or comments.

These may be useful when debugging toxcore locally, but are not useful in
unit tests.

To make it an abstract type everywhere except in network.c.

- rework ip_ntoa() to avoid use of static variables
- rework sort_client_list() to avoid use of static variables
- move static 'lastdump' into Messenger struct
- rework ID2String() to avoid use of static variables; rename to id_to_string()
- fetch_broadcast_info(): attempt to mitigate risks from concurrent execution
- current_time_monotonic(): attempt to mitigate risks from concurrent execution
- comment on non-thread-safety of unix_time_update

"All rights reserved" was incorrect. The project was licensed under GPL3,
which means a lot of rights are licensed to everybody in the world, i.e.
not reserved to the "Tox Project".

Compiling as C++ changes nothing semantically, but ensures that we don't
break C++ compatibility while also retaining C compatibility.
C++ compatibility is useful for tooling and additional diagnostics and
analyses.
|
|
It is still C code, so still compatible with C compilers as well. This
change lets us see more clearly where implicit conversions occur by
making them explicit.

In the future, all TODOs added either need a bug number (TODO(#NN)) or a
person's github user name. By default, I made irungentoo the owner of
all toxcore TODOs, mannol the owner of toxav TODOs, and myself the owner
of API TODOs.

This header is a requirement for the public API, therefore is assumed to
exist. It is a C99 standard library header, and _Bool is not intended to
be used directly, except in legacy code that defines bool (and
true/false) itself. We don't use or depend on such code. None of our
client code uses or depends on such code. There is no reason to not use
bool.

1. Current module (if C file).
2. Headers from current library.
3. Headers from other library (e.g. toxcore includes in toxav).
4. System headers.

They are now all uint16_t instead of sometimes being uint32_t.
Replaced some other uint32_t with unsigned ints.

Added some code to get real adapter broadcast addresses on windows.

Socket used to find the broadcast ip was not closed when there was
more than 16 broadcast interfaces.

Fixed a couple of issues related to that.
