This is the bulk of changes for the core C library.

The documentation has been extended to document the lifetime management
of objects explictly.

The concept of attributes has been removed - instead the translation from
configuration options to kernel request happens at the time of the line
request call and can only fail at this stage - the config mutators no
longer return any value.

If the caller has passed a config that is too complicated, the request
function will set errno to E2BIG which stands for: "Argument list too
long". If the caller has passed an invalid value to any of the line config
mutators, the error will be returned at the time of making the request.

The direction and edge options have been split from the former
request_type.

The objects are no longer reference counted and no longer can be the
responsibility for their lifetime shared.

There are many other minor tweaks everywhere.

Hi Kent,

this is another iteration of the new API. This time there are no big
changes, mostly just documentation and naming-convention tweaks.

I will push it out to a semi-official next/libgpiod-v2.0 branch and any
follow-up changes will be squashed into the v2.0 API there.

I haven't looked through all the code, but gpiod.h looks good to me, and
I'm sure any issues in the implementation will come out in the wash, so
go for it.

Cheers,
Kent.
