log: Don't define logging function 4 times

In log.c we use a macro to define logging functions for each of 4 priority
levels.  The only difference between these is the priority we pass to
vsyslog() and similar functions.  Because it's done as a macro, however,
the entire functions code is included in the binary 4 times.

Rearrange this to take the priority level as a parameter to a regular
function, then just use macros to define trivial wrappers which pass the
priority level.

This saves about 600 bytes of text in the executable (x86, non-AVX2).
