Previously the constructor for all of these would run at program
startup, consuming time before the application can enter main().
This is also particularly dangerous, given the logging system wouldn't
have been initialized properly yet, yet the program would use the logs
to signify an error.
To rectify this, we can replace the literals with constexpr functions
that perform the conversion at compile-time, completely eliminating the
runtime cost of initializing these arrays.
* ipc: Allow all trivially copyable objects to be passed directly into WriteBuffer
With the support of C++20, we can use concepts to deduce if a type is an STL container or not.
* More agressive concept for stl containers
* Add -fconcepts
* Move to common namespace
* Add Common::IsBaseOf
Makes the interface future-proofed for supporting other platforms in the event we ever support platforms with differing pointer sizes. This way, we have a type in place that is always guaranteed to be able to represent a pointer exactly.
Not using the return value of these functions are undeniably the source
of a bug. This way we allow compilers to loudly make any future misuses
evident.

This commit adds a network abstraction designed to implement bsd:s but
at the same time work as a generic abstraction to implement any
networking code we have to use from core.
This is implemented on top of BSD sockets on Unix systems and winsock on
Windows. The code is designed around winsocks having compatibility
definitions to support both BSD and Windows sockets.
