Add client trace lines and fix random client first-operation bug

Browse Source 
Add logging infrastructure to client.c mirroring the server's node_log
pattern, with trace lines for: init, async put/get/delete, begin
transfers, replay requests, all received message types (store ack, fetch
chunk response, redirect, reply, get blob response), disconnects, and
unexpected messages.

Add result/operation trace lines to random_client.c and fix a bug where
the random client never started its first operation (the condition
`result.type != TOASTYFS_RESULT_VOID` was always false on the first
tick since no operation was pending).
