[libvirt] [PATCH 0/2] Add support of SASL authentication for QEMU migration

This is a first contribution, I have tried to follow the most as possible rules marked in HACKING. I hope this commit will be conform with the specifications. make check OK make syntax-check OK make -C tests valgrind OK Currently with peer to peer migration provided by virDomainMigrateToURI, QEMU migration code uses virConnectOpen() which means that all authentication callbacks are disabled. Since no auth callback is present, SASL doesn't find any mechanisms and thus auth fails with the error: "authentication failed: Failed to start SASL negotiation: -4 (SASL(-4): no mechanism available: No worthy mechs found)" The PATCH 1/2 adds a new example to illustrate how to use peer to peer migration. This patch is not necessary to fix the problem and can be removed. It is provided to help reviewers by avoiding the necessary to create code that use this feature. Also as it demonstrates the performance of libvirt I have thought it could be interesting to keep it for new users. The PATCH 2/2 fixes the problem by configuring QEMU migration code to use virConnectOpenAuth instead of virConnectOpen. Indeed this function will call if necessary a callback responsible to fetching credentials.
