spidev.h uses _IOC_SIZEBITS directly. musl libc does not provide this macro
unless linux/ioctl.h is included explicitly. Fixes build failures like:

from .../build/spidev_test-v3.15/spidev_test.c:20:

ret = ioctl(fd, SPI_IOC_MESSAGE(1), &tr);

Move the input_tx code into its own small function.
This cleans up some variables from main() that are used only here.
While we are at it, check malloc calls instead of assuming they succeed.

Jon Corbet requested this code moved with the last changeset,
https://lkml.org/lkml/2015/3/1/144,
but the patch was not applied because it missed the Makefile.
Moved spidev_test, spidev_fdx and their Makefile infrastructure.
