Some clients do not close connections properly or do not keep
it alive, so each time the connection times out a corresponding
log entry is written into a log. These messages may spam the log
really hard.
This may be an issue if log is placed on internal flash - it may
prematurely wear a flash chip. This also prevents hdd from spinning
down if the log is located on hdd and the dlna capable tv is online.

Set the log level to "error" by default.

MAN:
Set this to change the verbosity of the information that is logged
each  section can use a different level: off, fatal, error, warn,
info, or debug
Example
log_level=general,artwork,database,inotify,scanner,metadata,http,ssdp,tivo=warn

Some users might create a minidlna root with symlinks
to shared locations. While this could potentially create
a vulnerability, the option should be available to allow
users to do this should they choose to.
