Algorithm was failing in case when overflow mode was enabled
but allocation of new message failed. It could happen if message
size exceeded buffer size. Losing track of buffered messages
can lead to logging processing freeze.

Added log_internal.h for internal APIs. Move functions out of
log_core.h. Log_core.h shall have only macros and functions related
to logging message creation. Log_core.h is included by log.h thus
number of dependencies in that headers must be limited to minimum
to allow including without risk of circular dependencies.
