Jaco Kroon 6dbeace0c7 res_odbc: cache_type option for res_odbc.

This enables setting cache_type classes to a round-robin queueing system
rather than the historic stack mechanism.

This should result in lower risk of connection drops due to shorter idle
times (the first connection to go onto the stack could in theory never
be used again, ever, but sit there consuming resources, there could be
multiple of these).

And with a queue rather than a stack, dead connections are guaranteed to
be detected and purged eventually.

This should end up better balancing connection_cnt with actual load
over time, assuming the database doesn't keep connections open
excessively long from it's side.
