* 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.
This allows us and users to reproducibly build verified versions of the
library with checksums. It will power the toktok-stack continuous build
with checked-in checksums at specific git revisions.
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).
"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".
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
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
This is to allow new group chats to coexist with old group chats. We do
not rename everything in group.[ch] to conference, yet, because it's not
currently necessary, and a general internal API overhaul is due at some
point anyway.
- Moved apidsl headers next to their generated versions. In the future,
perhaps all (or most) headers will be apidsl-generated, so the sources
should stay together.
- Try to find apidsl/apigen binary and astyle binary and use it for the
format test. Don't run the format test if these can't be found.
- Fixed incorrect parameter names (documented name didn't match code
name).
- Removed `@return` from functions that return `void`.
- Make sure every parameter is documented. This required moving the
planes and strides documentation to the function docs.
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.
- All global variables should be static unless they have an explicit
extern declaration in a header file.
- `to_compare` was not used in encryptsave and toxav tests.
- `break` in switch cases is not required directly after `return`,
`goto`, or a noreturn function like `abort`.
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.
It now enforces a bit more formatting. In particular, padding inside
parentheses is removed. I would like it to remove padding after unary
operators, but there seems to be no option for that.
I hadn't done this for the "fun" code, yet. Also, we should include
system headers after our own headers.
"In general, a module should be implemented by one or more .cpp files.
Each of these .cpp files should include the header that defines their
interface first. This ensures that all of the dependences of the module
header have been properly added to the module header itself, and are not
implicit. System headers should be included after user headers for a
translation unit."

- Mingw32 didn't read MSDN, so behaves badly despite lean and mean.
- Avoid alignment issues on windows with packed bitfields in the RTP header.
This change makes the program ill-formed in C99, but I don't know the correct
fix at the moment, and I don't want to keep the Windows build broken for too
long.
1. This mutation is never observed outside the function.
2. If it were (it's not), it would be undefined behaviour, since the
packet data goes out of scope a few instructions after the callback
returns.
- Any non-externally-visible declarations should be `static`.
- Casting away the `const` qualifier from pointers-to-const is
dangerous. All but one instance of this are now correct. The one
instance where we can't keep `const` is one where toxav code actually
writes to a chunk of memory marked as `const`. This code also assumes
4 byte alignment of data packets. I don't know whether that is a valid
assumption, but it's likely unportable, and *not* obviously correct.
- Replaced empty parameter lists with `(void)` to avoid passing
parameters to it. Empty parameter lists are old style declarations for
unknown number and type of arguments.
- Commented out (as `#if DHT_HARDENING` block) the hardening code that
was never executed.
- Minor style fix: don't use `default` in enum-switches unless the number
of enumerators in the default case is very large. In this case, it was
2, so we want to list them both explicitly to be warned about missing
one if we add one in the future.
- Removed the only two function declarations from nTox.h and put them
into nTox.c. They are not used outside and nTox is not a library.
- Don't cast between object and function pointers.
- Use standard compliant `__VA_ARGS__` in macros.
- Add explicit `__extension__` on unnamed union in struct (it's a GNU
extension).
- Remove ; after function definitions.
- Replace `const T foo = 3;` for integral types `T` with `enum { foo = 3 };`.
Folding integral constants like that as compile time constants is a GNU
extension. Arrays allocated with `foo` as dimension are VLAs on strictly
compliant C99 compilers.
- Replace empty initialiser list `{}` with zero-initialiser-list `{0}`.
The former is a GNU extension meaning the latter.
- Cast `T*` (where `T != void`) to `void *` in format arguments. While any
object pointer can be implicitly converted to and from `void *`, this
conversion does not happen in variadic function calls.
- Replace arithmetic on `void *` with arithmetic on `char *`. The former
is non-compliant.
- Replace non-`int`-derived types (like `uint16_t`, which is
`short`-derived) in bit fields with `int`-derived types. Using any type
other than `int` or `unsigned int` (or any of their aliases) in bit
fields is a GNU extension.
This removes the global logger (which by the way was deleted when the first tox
was killed, so other toxes would then stop logging). Various bits of the code
now carry a logger or pass it around. It's a bit less transparent now, but now
there is no need to have a global logger, and clients can decide what to log and
where.
Also, fix the hstox build that was taking half an hour. It now takes 5 minutes.
Also, perform distcheck on travis to ensure that make dist works. It's not
actually failing the build at the moment due to broken tests.
