Merge branch 'refs/heads/t/ll'

Two little cleanups related to the logging facility and two commits
which add the ll command to para_server and para_audiod.

The merge resulted in a conflict in afs.c due to the earlier merge of
the poll topic branch which replaced all calls to select() by calls
to poll(). The implementation of the ll server command introduced a
new caller of select(), afs_select(), which needs to be replaced by
afs_poll() to resolve the conflict.

* refs/heads/t/ll:
  New server command: ll to change the log level at runtime.
  New audiod command: ll to change the log level at runtime.
  daemon: Kill get_loglevel_by_name().
  server/audiod: Don't parse loglevel argument unnecessarily.
