[libc-commits] [libc] [libc] Add some types to netinet/in.h (PR #196932)

[Pavel Labath via libc-commits]

https://github.com/labath created https://github.com/llvm/llvm-project/pull/196932

Not including more types because I need to fix in_addr definition first.

This exposes stdint macros and types through the header, but POSIX permits that behavior (and explicitly requires that we define uint8_t and uint32_t).

No test as this is just adding a typedef, and I don't *think* we have tests for that, but I can add a "check that type is defined" test if that is desirable.
