Without head, States storage can't support append-write

When the supervisor needs to process a large amount of opaque data (for example, a nydusd instance has a large number of sub mounts, and the opaque is usually larger than 32kb), a recvmsg / sendmsg system call cannot process all data. The commit fixes the problem with multiple recvmsg/sendmsg calls and updates the test cases. Signed-off-by: Yan Song <[email protected]>

Should we check if fd is positive?

Should be ok, but maybe we don't have to limit it.

Why trigger and receiver have to run in parallel in separted goroutines?
