This series of patches fixes a possible memory exhaustion problem
observed in ovsdb-server in an intentional stress test. The first
three patches fix the problem:
json: New function json_serialized_length().
ovsdb-data: New functions for predicting serialized length of data.
jsonrpc-server: Disconnect connections that queue too much data.
The remaining two patches add a test. They are split into separate
patches because it seems reasonable to backport the first three
patches to older branches, but I am not sure about the test:
ovsdb-client: Make "monitor" command able to monitor all tables.
jsonrpc-server: Add test for disconnecting connections with too long
queues.
