Change Description

Updates the startIntTask method call in LinuxGpioDriver to include a stack size argument for the new thread. This matches the behavior of the read thread call in LinuxUartDriver.

The stack size argument was inserted into the middle of the list of arguments to match LinuxUartDriver. However, existing code that uses both priority and CPU affinity arguments will be broken if directly updated. In practice I am unsure if this is too big of an issue as cpu affinity arguments will likely be invalid stack sizes.

Rationale

The application author is responsible for setting the stack size of the task, not the framework

Testing/Review Recommendations

Currently untested. Building LinuxGpioDriver still builds standalone and building this code in an internal project was successful

Looks good to me!

Looks like the GPIO stubs file wasn't updated. @kubiak-jpl want to fix that? If not I'll get to it Monday.
