Upstream bug fixes:
- fix C++ tests with recent kernels which introduced stricter reconfigure
behavior
- fix a use-after-free bug in python bindings
- fix passing the event clock property to line requests in python bindings
- fix a memory leak in tools
- make sure the string buffers in line-info and chip-info are big enough to not
truncate the strings they hold below the size accepted by the kernel

Now that all in-tree users (avrdude and openocd) are capable to use
libgpiod v2 API, we can finally update libgpiod to the newer version.
While at, introduce the C++ wrapper as new package.
The Python package now uses OpenWrt's Python build infrastructure.

This reverts commit 983835afe6.
I merged the library update to v2.0 to fast, it breaks openocd build
due to API change.

This updates this library to the latest major version.
Since the Python binding build changed in this version,
let's switch to the Py3Package infrastructure.
Also the older v1 kernel interface is not used anymore,
so we can drop this part of the kernel configuration.

This library needs the kernel config option 'CONFIG_GPIO_CDEV_V1=y' to
be set. If this is not set, the tool 'gpioinfo' produces the error message
'error creating line iterator'. Add the missing kernel config option to
build CDEV with API Version 1 fixes this.

This removes Python-related build variants, and adds
PYTHON3_PKG_BUILD:=0 and minor build adjustments (where appropriate),
for non-Python packages. There should be no changes to build output.
This also updates some include paths for python3-package.mk and/or
python3-host.mk to be relative to the package Makefile.

Now that we only use kernel versions that support libgpiod,
we can remove the dependency on the kernel version.
This enables libgpiod to be used with linux 4.19.

Required kernel interface was introduced in kernel v4.8,
so add the kernel version as dependency for this library.

libgpiod is a C library with corresponding tools for interacting
with the linux GPIO character device (gpiod stands for GPIO device).
Since linux 4.8 the GPIO sysfs interface is deprecated. User space should use
the character device instead. This library encapsulates the ioctl calls and
data structures behind a straightforward API.
