The output format consists of a prefix carrying the syslog
prefix including priority and facility, the 64 bit message
sequence number and the monotonic timestamp in microseconds,
and a flag field. All fields are separated by a ','.

Future extensions might add more comma separated values before
the terminating ';'. Unknown fields and values should be
gracefully ignored.
sequence number and the monotonic timestamp in microseconds.
The values are separated by a ','. Future extensions might
add more comma separated values before the terminating ';'.
Unknown values should be gracefully ignored.

The human readable text string starts directly after the ';'
and is terminated by a '\n'. Untrusted values derived from
hardware or other facilities are printed, therefore
all non-printable characters and '\' itself in the log message
are escaped by "\x00" C-style hex encoding.
all non-printable characters in the log message are escaped
by "\x00" C-style hex encoding.

A line starting with ' ', is a continuation line, adding
key/value pairs to the log message, which provide the machine
readable context of the message, for reliable processing in
userspace.

Example:

The DEVICE= key uniquely identifies devices the following way:
b12:8 - block dev_t
c127:3 - char dev_t
n8 - netdev ifindex
+sound:card0 - subsystem:devname

The flags field carries '-' by default. A 'c' indicates a
fragment of a line. All following fragments are flagged with
'+'. Note, that these hints about continuation lines are not
neccessarily correct, and the stream could be interleaved with
unrelated messages, but merging the lines in the output
usually produces better human readable results. A similar
logic is used internally when messages are printed to the
console, /proc/kmsg or the syslog() syscall.
