John Baldwin b1012d8036 Account for AIO socket operations in thread/process resource usage. ...

File and disk-backed I/O requests store counts of read/written disk
blocks in each AIO job so that they can be charged to the thread that
completes an AIO request via aio_return() or aio_waitcomplete().  This
change extends AIO jobs to store counts of received/sent messages and
updates socket backends to set these counts accordingly.  Note that
the socket backends are careful to only charge a single messages for
each AIO request even though a single request on a blocking socket might
invoke sosend or soreceive multiple times.  This is to mimic the
resource accounting of synchronous read/write.

Adjust the UNIX socketpair AIO test to verify that the message resource
usage counts update accordingly for aio_read and aio_write.
