gnulib-common: prefer _GL_UNUSED over _UNUSED_PARAMETER_
There are more contexts where __attribute__((__unused__)) is
useful than just parameter lists. Also, naming the macro
_GL_UNUSED fits with the recent addition of _GL_ARG_NONNULL.
Preserve the name _UNUSED_PARAMETER_ for backwards-compatible
use in external projects.
* m4/gnulib-common.m4 (gl_COMMON): Create a more-appropriately
named alias for __attribute__((__unused__)).
