plugin: Removed obsolete TODO note.
Merged branch 'master' of git://git.tokkee.org/sysdb.
frontend: Fixed a memory leak in the connection context handler.

Previously, the ownership was not taken away from the thread-specific data
aftter removing the connection from the current context, thus leaking each
connection object.
Frontend: Improve debug log when destroying a connection.

The file-descriptor associated with the connection might not be open any more
and, thus, be -1. Instead of using that in the message, use the connection's
object name which includes the file-descriptor as used when accepting the
connection.
frontend: Force-close the connection in sdb_connection_close().

Previously, it would still be kept open if someone else referenced the object.
llist_test: Removed "sdb" from test names.
llist utils: Added sdb_llist_remove_by_name().

This function removes the first entry with the specified name.
llist_test: Removed "llist" from all test names.

No need to use overly long names.
