Dispatch a number of READ10 requests simultaneously, and await all
responses.
The iscsi-support test helper functions are currently all synchronous,
so this test mostly uses the bare libiscsi API. As new async tests are
added, we can make a more informed decision on which boilerplate code
can be split out.

Add ULL to all the large integer literals. Without this they can be
treated as being signed by the compiler (at least on 32 bit machines)
leading to underflow problems and strange output when calculating the
elapsed time.
7c6a3e4a0b wound up always forcing the
usage of gettimeofday (even when the more accurate CLOCK_MONOTONIC was
available) because the define to indicate its availability is in
config.h which wasn't included.
Fix this by including config.h, correct the misnamed variable in the
CLOCK_MONOTONIC branch and rename VERSION to PERF_VERSION to avoid the
naming conflict.
Move the scsi_free_scsi_task() call from receive_copy_results() to the
callers of this function to avoid that accessing the unmarshalled data
triggers a use-after-free.
