bug#20362: 25.0.50; Byte compiler doesn't know parameter list of `unintern'

[Philipp Stephani]

Consider a file with the following content:

    (unintern 'foo)

Loading this file works as expected, but compiling it generates the
warning

    unintern called with 1 argument, but requires 2

But `unintern' doesn't require 2 arguments.

That's the `advertized-calling-convention' at work here.  IOW calling
the function with only one argument still works but is deprecated.

Indeed. I only looked at the implementation, not the documentation. Sorry
for the noise.
