It's supposed to be used by parasite and restorer blob. It
has API equal to the core one -- with setfd, set_loglevel and
(the main thing) print_on_level fn. It currently supports only
strings, decimal and hex numbers (int and long).

Will need it to fetch log level for restorer code.

To teach restorer code the log levels we
need a separate file for their definition.

We can set a directory for log and image files.
crtools sets it as a current directory and then creates all files in it.
It works before we don't decide to change a mount name space.
I suggest to open a log dir and create files for help openat.

Useful if one need a prefix over module messages.
I use it in tty c/r, thus having something like
| TTY: master 0x31 index 2 fd 6 pid 5079 (create 1)
| TTY: `- slave 0x5c index 2 fd 255 pid 5080 (create 0 send 0)
| TTY: standalone slave 0x2e index 1 fd 3 pid 5079 (create 1)
in log. Which helps filtering messages.

If the option --log-pid is set, each process will have an own log file.
Otherwise PID is added to each log message.
A message can't be bigger than one page minus some bytes for pid.

The messages are filtered by their type
LOG_MSG - plain messages, they escape any (!) log level
filtration and go to stdout
LOG_ERROR - error messages
LOG_WARN - warning messages
LOG_INFO - informative messages
LOG_DEBUG - debug messages
By default the LOG_WARN log level is used, thus LOG_INFO
and LOG_DEBUG messages will not appear in output stream.
pr_panic helper was replaced with pr_err, pr_warning
shorthanded to pr_warn and old printk if rather pr_msg
now.
Because we share messages between "show" and "dump" actions,
before the "show" action proceed we need to tune up
log level and set it to LOG_INFO.
Also note that printing of VMA and siginfo now
became LOG_INFO messages, it was not that correct
to print them regardless the log level.

Instead of keeping all unrelated to
C/R procedure helpers in util.c move
logging related helpers to log.c.
