similar to: [PATCH 0/4] vsock: cancel connect packets when failing to connect

Currently, if a connect call fails on a signal or timeout (e.g., guest is still in the process of starting up), we'll just return to caller and leave the connect packet queued and they are sent even though the connection is considered a failure, which can confuse applications with unwanted false connect attempt. The patchset enables vsock (both host and guest) to cancel queued packets when a

Most of the patches are reviewed by Dexuan, Stefan, and Jorgen. The following patches need reviews: - [11/15] vsock: add multi-transports support - [12/15] vsock/vmci: register vmci_transport only when VMCI guest/host are active - [15/15] vhost/vsock: refuse CID assigned to the guest->host transport RFC: https://patchwork.ozlabs.org/cover/1168442/ v1:
