* 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.
* Removed `ARRAY_SIZE` and use NULL markers for end of array, instead.
The alternative is + size, but for these arrays, NULL markers made
sense, since they are arrays of non-null pointers.
* Made `INDEX_OF_PK` a self-contained macro, not dependent upon the
naming inside its call site. This is a minor change but makes the code
more local and reviews easier.
* No nested structs.
* Use only named function types ending in `_cb` for callbacks.
* Replaced two macros with functions.
* `++i` instead of `i++`.
* struct member names start with lowercase letters.
* It takes a bit of work to support `/**/` comments in preprocessor
macros, so I've decided not to support these. If a macro is complex
enough to need comments inside it, it's too complex. `//` comments are
allowed at the end of macro definitions.
* Callback typedefs must name their parameters.
* Enums must by typedef'd.
* Comments at end of `#define` must be `//` comments.
* Typedef structs must not be anonymous.
* `;` at the end of a `#define` is invalid.
* Callback typedefs must list their parameter names.
* No nested structs.
* No inline use of function pointer types. Only typedef'd callback types
are allowed.
* Enum types are spelled in Camelsnake_Case.
* The argument to `#error` must be a string literal.
It turns out, `unix_time` is also monotonic, and is used as such, so I've
renamed the new functions to `mono_time_*`.
2018-07-08:
```
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:
* compound statements (blocks, e.g. in if/else) must be non-empty.
Comments don't count.
* `=` is not allowed in subexpressions. We treat it as statement-only.
* `++i` is preferred over `i++` in statements.
* `Type_Names` are camelsnake-case.
Also:
* `#define` must be scoped. If it's used outside a scope, it must be
defined outside that scope (global `#define` does not need a matching
`#undef`).
This is now a style rule: you can only use typedef'd function types.
Previous rules now applied in `onion_*.c`:
* `struct`s must have a name (typedef of unnamed struct is not allowed).
* `++i` for increment-stmt, not `i++`, e.g. in loops.
* Only a single declarator per struct member declaration.
* Type_Names vs. variable_names.
Also:
* No inner structs.
* One declarator per member declaration.
* Function names are snake_case.
* Names ending in `_cb` are function types.
* `++i` is preferred over `i++`.
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.
Removed a pointless declaration of a function in lan_discovery_test
and cleaned up the one error message there. Did an entire restructuring
of the version_test using macros that resulted in fewer lines of code but more
thorough testing.
Formatting of version_test.c
back to old way, save comments and one change
Missing space
My greatest enemy
Add `#include <cstdio>` for `std::printf`.
Make tox.c unambiguously parseable.
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.

Use run_auto_test.h test fixture for some auto-tests.
Most of the auto-tests should use this fixture, but I've only done a few
to set an example.

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.
* Consistently use `num_packets_array` to get the packet count in the
packet buffer.
* Use `const` in more places.
* Typo fix: begginning.
* Rewrite `length < 1` for unsigned int to `length == 0`.
* Limit scope of some loop variables by using for-init-decl.
* Use early return in error paths to reduce indentation and for clarity.
* Use `net_unpack_*` instead of manual `ntohs`.
* Fix an uninitialised stack variable copy.
* Fix a potential null pointer dereference.
* Consistently use `get_crypto_connection`. It was inlined in some
places. I de-inlined it now.
* Add Loggers to some functions in preparation for adding log statements.
Mostly documentation + comments. Some cases where code was removed
in exchange for more compact/less sprawly for loops. Introduced a
function that removed like 30 lines of repeated code.
Rename args `host:port` from `address:port`.
The *address* is well known as *Tox Address* in this project. Then we
should reserve *addres* to it, and use *host* to express the hostname or
IP address in TCP domain.
The C compiler warns because the value is initialised in a loop and used
outside of it. In this case, it's always initialised, but changing the
value of `NUM_PORTS` can change that.
