It's nice we are able to compile with `tcc`. Let's not break that.
CompCert is also neat, but its interpreter mode doesn't work on tox, so
we only use the compiler.
Tokstyle no longer allows:
* Includes inside an `extern "C"`
* Comments on function definition and declaration to be different.
* Doxygen comments commenting on other doxygen comments.
* `crypto_memcmp` was replaced by more specific functions. We never want
to compare arbitrary amounts of data this way. We use these functions
to compare key material.
* apidsl has been bothering people, so now we un-bother them. You're
welcome.
* Added the memlock/unlock functions from the New Group Chats branch.
* Remove some system dependencies in crypto_core_mem.c.
* Renamed UPPERCASE_NAMES to Snake_Camel_Case names.
* Fix Appveyor CI build
The problem was that when running commands in powershell, any stderr
output is treated as an "exception", stopping the build even if the exit
code of the command was good.
* Add workarounds to get Cirrus CI to pass
Removing the cache isn't great, but the build is still only 5-7 minues,
so it's not terrible either.
Disabling the tcp_relay test also sucks. It passes locally, so we're
likely getting caught in a firewall or something like it somewhere.
