We're already using it implicitly but GCC may change the default
standard to gnu99 at some point, so use gnu89 explicitly whenever
building C files.

The test-suite python scripts is added to bin_SCRIPTS in Makefile.am.
This means it's not distributed by default. Add it to dist_bin_SCRIPTS
and make it part of the distribution tarball.

Python bindings are missing the functionality provided by the core C
library's gpiod_line_update(). Extend the Line class with the update()
method that allows to re-read the line information from the kernel.

Kernel release candidate version strings seem to not be working
correctly with python's version.parse() function. Split the string
retrieved with os.uname().release using '-' as delimiter and pass
only the first part - 'major.minor.release' - to version.parse().

Mainline commit 2c60e6b5c924 ("gpiolib: never report open-drain/source
lines as 'input' to user-space") in the linux kernel has now been
backported to v5.2 stable branch and released in linux v5.2.11. We can
now enable back the assertions that were previously failed in test
suites (core, C++ and python). The required kernel versions must be
updated as well.

Currently the only tests we have for python bindings are in a simple
script that makes a lot of assumptions about the environment and
doesn't even work anymore with recent kernels.
Remove it and replace it with a proper test-suite implemented using
libgpiod and the standard python unittest package.
