Track the length of the client pending output buffers (still to transfer) in a new field in the client structure.

It is now posible to flush all the previous saving points in redis.conf by using a save directive with a single empty string argument, like it happens for CONFIG SET save.

Fixed some typos in redis.conf.

Don't change the replication state if SLAVE OF is called with arguments specifying the same master we are already connected with. This fixes issues #290.

On crash print information about the current client (if any), command vector, and object associated to first argument assuming it is a key.

Regression test for the main problem causing issue #141. Minor changes/fixes/additions to the test suite itself needed to write the test.

Protections against protocol desyncs, leading to infinite query buffer growing, due to nul-terms in specific bytes of the request or indefinitely long multi bulk or bulk count strings without newlines. This bug is related to Issue #141 as well.

Fixed replication when multiple slaves are attaching at the same time. The output buffer was not copied correctly between slaves. This fixes issue #141.

Fixed a config docs typo.

AOF fileds in the global server state, and define names, renamed with more consistent names. More work to do.

server.appendonly -> server.aof_state, and many comments added in the server global state structure in the process.

Redis test: when assertion fails print not just the expression but also expanded values in the error message.

Fix issue #247 and add a test case
