liblog: audit declare LIBLOG_ABI_PUBLIC

(cherry pick from commit be1d3c21b57d3e67c6a9682f3b2f0838486a3ee8)

- replace <sys/cdefs.h> with local "log_cdefs.h" which
  fortifies and expands definitions, adding LIBLOG_ABI_PUBLIC,
  LIBLOG_HIDDEN, LIBLOG_ABI_PRIVATE and LIBLOG_WEAK.
- clearly tag each interface as LIBLOG_ABI_PUBLIC, LIBLOG_HIDDEN,
  LIBLOG_ABI_PRIVATE, LIBLOG_WEAK or static depending on scope
- Add -fvisibility=hidden to ensure nothing else leaks
- some code standard adjustments
