While () and (void) are synonymous in C++, we use () everywhere else so
fix the only exception. This DOES NOT change the ABI as the generated
symbol is the same (at least as verified on gcc and clang).

We have two helpers that do the same thing: given a key and a map, they
return the associated value or throw an exception if the map doesn't
contain it. The difference is just in the type of the exception. Remove
one and reuse the other. While at it: modify the names a bit for better
readability - especially the mapping function which is not limited to
just mapping enum types.

Extend line_config to expose a new method - set_output_values() - which
wraps the new C function for setting multiple output values at once.

Implement the copy operator for line_settings. We have a copy() method
for line settings in C API while in C++ it's useful to copy line_settings
returned in an std::map from line_config.get_line_settings().

We explicitly resolve all global C symbols from libgpiod to the top-level
namespace. Fix it wherever its missing (mostly for C enum types).

The code is not consistent with regard to following the last element in
enums and struct definitions with a comma. Unless the last element is
guaranteed not to change (e.g. '{ }', or NULL), follow it with a comma
treewide to avoid churn in git when adding new values.

While we use it for edge event timestamps exclusively at the moment,
the actual enum names shouldn't limit its application and simply just
refer to existing clock types known by the GPIO uAPI. The relevant
functions are still called set/get_event_clock() as it's in line with
their functionality.

Use enum types explicitly across the entire C API. Modern compilers can
catch some bugs with enums and it also helps IDEs and general readability.

[Viresh: make rust bindings work with negative enum values]

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.
