Changed paths: M src/lib-http/http-client-peer.c

Log Message: ----------- lib-http: client: Fix panic occurring at connection failure.

In http_client_peer_connection_failed_pool(), all linked queues are notified about the connection failure through http_client_queue_connection_failure(). That function can internally link and unlink peers to the queue, including the calling one. This means that the peer->queues array can be modified while it is iterated in the array_foreach() loop. The problem is fixed by making a local copy of the peer->queues array.

Changed paths: M src/lib-http/http-client-queue.c M src/lib-http/test-http-client-errors.c

Log Message: ----------- lib-http: client: Fix handling of servers with several alternative IP addresses.

This also addresses an assert failure occurring with parallel clients:

Panic: file http-client-queue.c: line 518 (http_client_queue_connection_failure): assertion failed: (queue->cur_peer == peer)
