Adding a default timeout may not be representative of every
usecase for gb_loopback. Also, tests may continue to run
on the driver in case of a timeout.
To avoid adding a default timeout, handle SIGINT so that when the user
presses ctrl-c the test are stoped. The user can still specify a timeout
value with the -O option.

Patch "c3b0a32 Loopback_test: use poll instead of inotify"
added a optional argument for the user to specify a timeout value,
but did not use this parameter in the actual poll function. The
default of 30 seconds is always used.
Fix this by actually using the the poll_timeout parameter so the user
can run long tests.

Inotify does not handle sysfs events, so use poll instead.
The loopback kernel driver will send a notification when the test is
complete. So, open a poll file descriptor for every enabled device,
and after starting the test, wait for an event from each device.
After all events are received, read the total number of iterations
and make sure the test is complete.
Also, add missing stdint header which was included in inotify.

Its unrealistic to expect 50 loopback devices,
and the mask parameter can hold up to "int" anyways
so decrease to max number of devices to sane value.

Its useful to get a CSV output on stdout for test frameworks to read
and parse the results. However, a csv file is not always needed.
Add the -z option to create/append a csv file only when the user
asks for it.

This lets us test for any number of entries, no need to do an
ARRAY_SIZE-type comparison. This fixes a build warning of comparing
signed/unsigned values.)

We read an int, don't treat it as a unsigned value, especially when
comparing it to a signed value.

Move the loopback test to the greybus main repo, as we will be adding
more tests over time and it doesn't need to be burried in the gbsim
repo.
This moves the latest version from gbsim to this repo and fixes up the
Makefile to be a bit more "smart" when building the code.
