Provide a log driver that broadcasts RFC 3164 messages to syslog servers. rsyslog is one implementation of such a server.

The messages are sent to the local broadcast address 255.255.255.255 on port 514.

The environment variable log_hostname can be used to provide the HOSTNAME field for the messages. The optional TIMESTAMP field of RFC 3164 is not provided.

Log format ---------- -- 2.25.0

If CONFIG_LOG=n, we still expect output for log_err(), log_warning(), log_notice(), log_info() and in case of DEBUG=1 also for log_debug().

Provide unit tests verifying this.

The tests depend on:

CONFIG_CONSOLE_RECORD=y CONFIG_LOG=n CONFIG_UT_LOG=y

It may be necessary to increase the value of CONFIG_SYS_MALLOC_F_LEN to accommodate CONFIG_CONSOLE_RECORD=y.
