log.h really should only include the bare minimum of other headers, as it is really pulled into pretty much everything else and already in itself one of the most basic pieces of code we have. Let's hence drop inclusion of: 1. sd-id128.h because it's entirely unneeded in current log.h 2. errno.h, dito. 3. sys/signalfd.h which we can replace by a simple struct forward declaration 4. process-util.h which was needed for getpid_cached() which we now hide in a funciton log_emergency_level() instead, which nicely abstracts the details away. 5. sys/socket.h which was needed for struct iovec, but a simple struct forward declaration suffices for that too. Ultimately this actually makes our source tree larger (since users of the functionality above must now include it themselves, log.h won't do that for them), but I think it helps to untangle our web of includes a tiny bit. (Background: I'd like to isolate the generic bits of src/basic/ enough so that we can do a git submodule import into casync for it)
