[PATCH v2 0/6] spi: Add file i/o to spidev_test

[Joshua Clayton <stillcompiling@gmail.com>]

Add to spidev_test, the ability to read from and write to a file.
Clean up code along the way.
As I finished, I found that a request has been made to move
spidev_test from Documentation to tools, so I did that as well.

Thanks to Mark Brown and Anton Bodarenko for feedback on v1

v2 Changes:
- Move spidev_test to tools in the first commit instead of the last.
- Drop the patch that formats tools/Makefile
- Drop the patch that changes rx to a local variable in transfer()
- Check the result of malloc everywhere it is called.
- Change all the patch subjects to spi: spidev_test
- Removed a check of the spi transfer buffer size, in favor of
    letting the kernel give an error in the ioctl if too big.
