Build with musl

I tried to compile with musl, but got errors:

I don't target musl. I've never even used it, actually.

Those types come from stdint.h. If you put #include <stdint.h> (almost) at the top of utils.h, does it work then? There may be more places it's necessary.

Did you try to continue with that? I don't primarily target musl, but if it's a matter of adding some includes, I can at least do that.

I recently got some more feedback from people building with musl, and it's not something I want to support now. FlashMQ targets GNU/Linux, so glibc is fine.
