We're currently unintentionally exporting a bunch of symbols that should
remain local to sub-modules. Use __all__ where appropriate so that we
don't re-export standard library functions such as select() etc. in the
gpiod module.

The docs don't mention it but currently passing None as the timeout to
one of the event wait methods works like passing 0 to select() - the wait
method returns immediately. Change it to a more standard behavior - None
makes the method block indefinitely until an event becomes available for
reading.
This is a slight change in the behavior but let's hope nobody complains
as libgpiod v2 is still pretty recent and its adoption is (hopegully)
not wide-spread yet.

This commit is the result of a squash of all the commits created during
the development of libgpiod v2. This is done to preserve bisectability
of the git tree. It contains significant re-writes of the core C library
as well as C++ and python bindings. The tools have been adjusted to work
with the new API but have not undergone significant changes yet.
This commit contains the bulk of the work on libgpiod v2 but the
development continues with more changes planned.
