MEDIUM: lua: Add stick table support for Lua.

This ads support for accessing stick tables from Lua. The supported
operations are reading general table info, lookup by string/IP key, and
dumping the table.

Similar to "show table", a data filter is available during dump, and as
an improvement over "show table" it's possible to use up to 4 filter
expressions instead of just one (with implicit AND clause binding the
expressions). Dumping with/without filters can take a long time for
large tables, and should be used sparingly.
