This thread seems to have gone a bit cold since March, and in the
meantime I have implemented my own patch (because I didn't notice this
thread) which is very similar too, but slightly more comprehensive than
Deweloper's one.

I will send my patch as a separate patch e-mail, the main differences
from Deweloper's patch are:

- It has a config option so you can keep the current behaviour of
logging everything at LOG_ERR and save <200 bytes.

- It keeps 'syslog_level' as a static variable rather than passing an
extra parameter. It's not as neat but generates smaller code.

- I've been through all of the bb_info_msg() calls that were removed
between Busybox 1.24.2 and 1.25.0 and restored all of the ones in
applets that log to syslog.

I hope that this will be acceptable for inclusion, as this is an issue
that has obviously affected multiple users.
