46b89eb723 core/msg_bus: fix shift on 8-bit platforms
The previous shift would wrap if the compiler defaults to 16 bit words.
Use explicit `unsigned long` integer constants to mitigate that.

c29f133a63 core/msg_bus: clarify API of msg_bus_post()
Receiving threads must not modify the contents of the message as this
is racy by definition.

Also make `msg_bus_post()` accept `const void*` instead of `char *`.
