[libgpiod v2][PATCH 3/3] core: rename uAPI related variables and functions to uapi.

[Kent Gibson <warthog618@gmail.com>]

Rename variables using the "buf" suffix to a "uapi_" prefix to identify
them as being uAPI types.
Similarly, rename the corresponding uAPI conversion functions from
"kernel" to "uapi".
