* 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).
* Fix `toxav_get_tox` to return tox, not messenger.
* Fix the casts from Tox* to Messenger* in toxav_old.c.
* Pass Tox instead of Messenger to public group AV callbacks.
* Constant-style macros can't be function call expressions. These must be
function calls themselves.
* Assignments can't be used as expressions.
* Therefore: `while` loops should not be used as a `for-each`
construct. Use `for`, instead.
* No anonymous structs.
* No assignment expressions.
* Only one declarator per struct member declaration.
* Named callback types only, no inline types.
* No `;` empty statements.
* `++i` instead of `i++`.
Avoiding a cast in toxav_old.c avoids some potential (and real) bugs.
* Named callback types only.
* No anonymous enums or structs.
* `++i` instead of `i++`.
* Don't use enums to specify integer constants. Enums should be
enumerations. All values of an enum type should be listed[1].
[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.
* Don't use anonymous enums (`typedef enum { ... } Name;`).
* Don't use macros to generate structs (too magical, hard to grep).
* Assign output parameter once, and don't access it a lot in the
function body.
* Don't pass type names as parameters to macros (this is C, we don't have
templates, sorry).
* All function-like macros must be do-while(0).
* `++i` instead of `i++`.
* No assignment-expressions.
* No void-casts.
The void pointer here only adds opportunity to introduce bugs and doesn't
actually make things more layered. It's just the code lying about being
layered while it's actually spaghetti.
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.
* 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
```
This change does not include the addition of VP9. We do that in a
separate pull request.
Changes:
* fix the video bug (video frames larger than 65KBytes) by sending full
frame length in alternate header field
* improve video frame reconstruction logic with slots
* configure video encoder and decoder to be multihtreaded
* set error resilience flags on video codec
* change encoder and decoder softdeadline
This also adds RTPCapabilities and a header field to tell the receiver
about capabilities used in encoding this frame. It is intended to contain
settings relevant to the current frame being sent.
follow TokTok#731. This commit
completely removed all things in namespace bit_rate, and deprecated
functions are to be added back in another commit. set_xxx() is treadted
as a property of namespace audio&video, same as bit_rate change event.
toxav_basic_test is fixed, either.
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
as iphydf said.
