Avoid casting back and forth between void-ptr.
In windows network code, we implement inet_pton and inet_ntop, which take
void pointers. We can do slightly better because we already know the type
when we call these functions, so we can avoid casting between void
pointer and the addr struct types.

Standardise on having a comma at the end of enums.
Most of our enums already have one. Some didn't. Tokstyle is going to
require commas at the end of enumerator lists in enum definitions.

Fix up comments a bit to start being more uniform.
Tokstyle (check-cimple) will start enforcing comment formats at some
point. It will not support arbitrary stuff in comments, and will parse
them. The result can then be semantically analysed.

Improve Windows compatibility of toxav code.

Fix style in toxav.c.
* Use Camel_Snake_Case for type names.
* Use at least 4 characters for constant names. I.e. `END` is a type
  name, but `RETURN` is a constant name. This is because `DHT` is a type
  name (yay consistency).
* Using `min_*` functions instead of MIN, we can avoid a cast.
* Use `for`-loops for for-each-frame semantics instead of `while`.
* Don't use assignments as expressions.
* `++i` instead of `i++`.
* Function pointers are dereferenced automatically, so no need to
  manually do so.
* Avoid void pointers that lie about not being spaghetti code. Toxcore
  and toxav are both spaghetti and shouldn't pretend anything else.
* Don't use empty statements (e.g. no `;;` anywhere in the code).

[1] I don't know what to do about bit masks yet, but given that enums by
C standard can only go up to 32767 portably and 2^31 in reality, they are
probably not useful for 64 bit bit masks.

Style fixes in TCP code; remove MIN and PAIR from util.h.
* 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.

Split bit_rate_set(), one for audio, one for video.
Fixes #572.

As discussed in the issue, there's a risk that toxcore may not hold the
maximum bitrates libvpx supports, if toxcore insists on using integer
type. I initially proposed to have another flag in set(), so that we can
use unsigned type instead. iphydf came up with a better solution, that is
splitting the original functions, one for audio, one for video. Now, we
could safely replace int32_t with uint32_t.

Also: clean video_bit_rate_invalid()

Though this is not a part of issue #572, as it's used in the
toxav_bit_rate_set(), i cleaned the code. As mannol said, there should be
a check. Uint32_t is large enough to hold the maximum bitrates libvpx
supports, but user may pass a value larger than uint while smaller than
uint32_t. Thanks to the reminding from nurupo, it's no longer a stub
function.

Bitrate error enums are shared for both audio and video
https://github.com/TokTok/c-toxcore/pull/578#issuecomment-360095609, just

Add a monolith_test that includes all toxcore sources.
This requires that every symbol, even if static (file-scope), is unique.
The idea is that we can easily run "whole" program static analysis on
programs that include monolith.h ("whole" is in quotes, as we don't
include dependencies like libsodium in this static analysis).

Update license headers and remove redundant file name comment.
"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".

3f24f04876 Setup autotools to read .so version info from a separate file
We want to use the same libtool style .so versions in both build systems,
ideally both systems should read the version information from the same
configuration file.

This commit introduces an so.version configuration file and sets up
the autotools to use it.

The version numbers in so.version define the ABI compatibility and should be
updated prior to each release.

implements #323

7122d2e862 Use after free reported in #278 occurs because toxav_kill()
calls msi_kill() (toxav.c:180) which frees msi_call instances (msi.c:161)
which are then used when call_remove() (toxav.c:1136) is called.
This fix prevents call_remove() from calling invalid pointer.

Fixes #278
